Changed mine on my 2013 yrs ago..$16 part..dealer didn't even know what CPS was..tried to tell me my computer was fried..went to a couple jeep forums.found the fix..Love my Jeep ppl
Thank you for putting this on RUclips. I too had a similar problem with my wife's 2013 Jeep. Had the same problem for about 1 and 1/2 years, took it to a Jeep dealer and spent a lot of money and they could not fix it. I did what you suggested and the Jeep drives like a new vehicle. I'm even getting about 3 more miles per gallon. I rarely comment on social media. I just wanted to say Thank You for taking the time and posting the solution!
Bingo! Same thing happened to my 2016 Jeep just was not running great and it finally pulled a code and check engine light came on…it was the Crank Position Sensor and called NAPA and they said they had one in stock. I bought it and changed it with like one bolt holding it on and drove it the next morning…OMG…it was like a new car…fun, quick, responsive again and me very happy!!!
Matt I was wondering if you had an issue when you snapped the throttle quick if it would choke out before revving up? Was looking at an 18 Jeep for my daughter the other day and I was doing that when I started it at the dealer. Thanks for any input.
@hd100thjd Yesss just did mine today. It would choke out then lunge forward like I had NOS 😂 try to get it for cheap and hope thats it. For me it was around 40mph 3rd gear i think. 2012 wrangler
@@matthew9826 Just brought a 2018 JK 3.6 3 weeks ago. My only issue is I feel it’s slow or doesn’t come out the gate running fast like I have to floor it to get up to 55/65 Mph. The dealership says it’s fine. So my question is would the CPS help far as speed or horsepower? Help
@@tellyjones2434 Honestly, these engines are underpowered. The torque doesn't kick in until like 3500 4000, RPM. I thought the same thing when I bought mine new. I just started shifting later rather than sooner. I'm assuming you have a manual?
I have a 2012 RUBI having the exact same issue and of course no codes to help diagnose the cause. This is a manual which would jerk me around with every hiccup. With almost 155K on the clock thought it was fuel pump related. Read on line about the crankshaft position sensor so changed it yesterday. So far so good. Thinking of also changing the camshaft sensors which might be overkill but with my current mileage might not hurt. Glad your is fixed and hopefully hasn't had any more issues.
Well kind sir, 3 years later I watched your short video and indeed it made my day. My '13 Town & Country has a new genuine Mopar CPS and it hasn't run this well in 18 months. Dealer couldn't figure it out - similar story to many commenters here. Many thanks for leveraging what you learned by showing us all what it takes.
This video made my day. Have the same 2013 Jeep, and had the same problem. Also frustrated me for a little over a year. Started so infrequently I thought it might be a transmission issue so got a flush, nope. Then a new air filter, nope. Then a dealer guy drove it, no luck. How about a new MAP sensor, nah. Finally found this vid down a rabbit hole that began when I started using the adjective “hiccup” to describe the feeling in acceleration. Got the part, installed and the Jeep feels brand new. I can’t believe how easy that was to fix and how hard it was to figure out. Hell yeah. Thank you. I was about at my wits end ;)
I've been trying to figure out this issue with my 2012 wrangler! Since you changed the crankshaft have you had the stalling issue at all? I'm at 180,000 km
Update!! Mines a 2013 with almost 42,000 miles. I put a comment on here about an hour or so ago. I went right down to O’reilly and they had ONE in stock. Here’s to hoping that’s my issue. Thanks again brother.
Thank you for the video!!! My 2015 Jeep Wrangler unlimited at highway speeds lost power and had the RPMs go to 0 for a split second and would regain power and be fine for several days before doing it again. This happened four times to me. I was telling my dad about it at Christmas yesterday, he said, “it might be your crank sensor”. Well, thanks to my phone listening in on our conversation that night, I was scrolling down my RUclips feed and found your video, 3rd video down. And thought what the hell, I’ll try it for $20. Today the jeep ran great, I picked up the sensor at O’Reilly’s, went to the gym. When I was leaving the gym, for the first time the Jeep starting running like shit and had no power. Misfiring and finally threw a code and what do you know it was the crank position sensor. I changed the sensor and cleared the code in the McDonald’s parking lot and the Jeep ran like new on the way home. Thank you again for taking the time to make the video!
Just bought my Jeep. Yeah, had high miles, so i didn't expect perfection- but I am retired E.O.D. - so not about to tolerate any BS. Anyway, I am jazzed to see this vid ! Tomorrow will switch it out ! Thanks! Wulfy OG
I’ve replaced almost every sensor and was about to replace the throttlebody because of hesitation and power loss and tomorrow I was going to pull out the TIPM and replace it. I’m gonna try your trick and I hope it saves me a lot of money and frustration. Thank you.
Thank you for this info. My 2013 started having this issue, stuttering on acceleration, and once it even lost all power while driving. Though after 15 minutes, I was able to start back up and continue on my way. No codes ever showed up. I bought the crank position sensor within minutes of watching this video, and replaced it myself. Solved the problem immediately. Tip: wait at least an hour after driving to replace the sensor. Everything down there gets real hot!
AMEN !! same symptoms... 2015 JKU Sport. Suddenly no throttle, RPMs dropped to 0 periodically, then comes back. Gradually started stalling too. Within a week I found this post. Replaced the sensor in 10 minutes. Problem gone. THANK YOU !
I miss diagnosed a vw jetta and I changed the crank sensor and it gained more power too. From my experience i always thought the crank sensor ether works or doesn't now i became a believer. And it still doesn't make sense.
Agreed, maybe it has something to do with this style sensor. All the sensors I've changed in the past just straight up failed but they were also on the outside of the engine.
@@matthew9826 the only thing I remember when I changed it the plug on the outside was soaked in oil and I cleaned it before I installed the new crank sensor. Maybe that also had to do something with it.
Had the same problem a few years back. I did take it to the dealership with same response. Took it home bought the part and replace it in 15 minutes. Problem resolved. By the way mine was shutting off while driving from a stand still and it would love to do it in intersections.
Thank you very much! I changed the spark-plugs several months ago because of this issue at 60K miles 2012 Rubicon, but the issue continued. Just replaced the sensor and I am going for a 40 miles ride and hope the problem is solved. One thing I noticed was that the rubber seal from the old part was flat compared to the new one which makes me wonder. Thanks again!
Same thing started happening to me. At first it was like my engine shutoff really fast for like a second then kicked back on. Then it started happening until it shut off on me at a red light, at a stop light and almost put me on the side of the highway. It turned the engine off and left my electrical on., didnt throw any codes as well. Started happening to me around 190 thousand miles. Currentmy have 242k on mine. It was the crankshaft position sensor. Had the same issue one time on a grand cherokee yrs ago . Glad u got ur figured out and fixes
I had one of them go on my 2015 Rubicon on same engine. Scan tool told me which one to change. My symptom was traction lock light would come on over 75Mph, which would lock up rear brakes which Jeep simply overpowered. I had to turn off traction control from switch and when I stopped, smelled the bakes burning. It would also throw the check engine light. Once crankshaft sensor replaced.. all fixed. Occasionally I got EVAP check engine light on also, that has gone away also since changing this crank shaft sensor so maybe it was all related and threw codes being on same BUS network.
Just changed one on a 2013 Jeep Grand Cherokee with about 75k miles. Worked perfectly! No CEL but it would jerk while accelerating at lower speeds. Thank you for this video!!
Same exact issue with my '14. Could not figure it out for the longest time and got so annoyed and pissed. Fixed my hesitation problem and I think it even shifts nicer as well. Thanks for the help and heads up.
Just hit 250K and my 2012 is doing the same now at least twice a week and shutting down. I just changed mine, 10 min tops, and fingers are crossed. Thanks!
OMG!!! I can't thank you enough. Mine started about 8 months ago and I was going insane. I even replaced my valve body because I "thought" I knew what it might be. $20 instead of $500.....I feel like an idiot.
@@brianlackey3834Awesome! I hope this definitely fixes your issue. It seems like even the dealerships still haven't caught on to this. There's still people taking their Jeeps to the dealer and they're saying nothing's wrong with it.
@matthew9826 I believe you. That's why I call them "Stealership's." Still can't believe I wasted $500 on a valve body swap. Good thing I did it myself or I would have wasted over 1K. Thanks again brother!
I changed my camshaft position sensor and crankshaft position sensor at the same time. I have a newer Jeep and it was not in an easily accessible location as yours but it was still cheaper than taking it in to the shop
bruh, this is my issue, guaranteed. I am just under 50k miles on a 2015 JK and this sudden loss of power "for a second" thing just started happening to me after I shipped my vehicle from Hawaii to San Diego. One quick YT search and here I am. Thanks.
Can't wait to try this on my 2012. Dealer said it was an oil gallery plug and that repair did nothing. Same symptoms: stalling on initial acceleration, stalling when in 6th gear at 60+mph, cruise control canceling when it stalls, no error codes, los of oil pressure when it happens. Thank you!
@@isthereafeeforthis Awesome!!! I'm happy to hear this fixed it for you. Unfortunately you're not the only one that went to a dealer and they told you there was nothing wrong or something else. It happened to me and a couple other people in the comments, it's kinda sad and seems to be a common issue I don't understand how they don't know this is the problem.
I have an issue on a child start. When placing my on the brake and shifting from park to reverse I will get hesitation with it occasionally stalling. Once the Jeep is up to temp, I don't have any issues.
@Mark Deluisi yeah that kind of does sound like the torque converter, but the part I was talking about only costs around 20 bucks. I'd go ahead and give that a shot. Maybe it'll fix your problem, and if not, it was only twenty bucks.
Absolutely crazy!! My girlfriends 2014 rubicon has been doing this, just going down the road and it suddenly loses power like it's starving for fuel then dies. Wait a few minutes and it starts right up like nothing happened and maybe 2-3 month later it happens again, no codes or any real sign of a problem. Very intermittent, definitely worth throw a cheap part at it and see if that will resolve the issues. Thank you for posting
@@matthew9826 So I picked up the part and went under the jeep only to find the bolt that holds it in is snapped off so obviously this part has been changed before so now I'll have to figure out how I'm going to drill it out in a tight space before I can replace the part.
@@tomfoolery8640 dang how was it even staying in with the bolt broke off? Heck that could actually be your issue right there with the sensor not being fully seated
@@matthew9826 looks like they use form a gasket or gasket sealer to hold it into place, I'm hoping when i take out the sensor there will be enough of a nub to work with as far as extracting the remaining part of the bolt. still i know this is going to be a hold your breath and hope for the best.
Thanks a lot....I have the same symptoms on my 2013 jk....I will change the cranck sensor and hopefully it works....I been dealing with this problem for a long time and also the dealership has not been able to fixed it but they sure charge for their time waisted.
Thanks brotha, that was exactly what was wrong with my Jeep. Bought the part and just like you said, five minutes and the problem solved. (Jeeping in the USVI)
Hoping this is my issue. Going to pop one in later today. Put the new one in and no immediate changes yet. Its slightly better but the issue is still there. Im hoping i just need to give it time. Ill see how it drives home from work tonight.
I’m Trying this method ! I recently got 2016 Jeep Wrangler Stick shift , started having problems Not being able to turn on . Dealerships couldn’t figure out said it was PCM , changed a new one . Now it’s a ‘ Tipsdip ‘ line that runs to the PCM . Anyhow Now it turns on fine , but on the freeway my Jeep started to pull foward on first gear and barely getting second gear . ( after I was bumper to bumper on a 99 degree hot weather ) So Now I’m trying this Method . Hopefully this can Actually fix the Jeep . Thanks
Mine went bad around 90k miles and I was pretty sure the CPS was the problem but like you, it wouldn't throw a code. I drove it for a bit longer and it slowly got worse, eventually it threw a code and then the dealer fixed it under warranty. Knowing what I know now, I'd just fixed it myself and sooner. It's lame that it takes so long for it to trigger the code.
I hope this is the fix for what I believe is the same issue. Over the las week while on the freeway my Jeep would fluctuate in speed. The ABS light would come on along with the battery light for a split second. The Speedometer would drop from current speed of 60/65 down to 40 mph and then back. Meanwhile I felt a loss of power even with my foot hammered down on the gas pedal. No Codes show on the dash. I turned around to go back home and maintained speed of 60mph with no issues. Off to Riley's for a Crankshaft Sensor.
Hopefully thats what my issue is, i have ordered the part and just waiting now. Only had just done 60,000Kms started about a 1.5years ago when in crusie control and it cancelled out of it and showed the red lighting bolt and would surge forward under its own power on throttle. No engine codes ever. Pulled over did the google mechanic thing and did the throttle peddle reset and drove on. Didnt saw the issue again untill 6months, same issue fixed it with peddle reset. Then became monthly and then once ever week and became daily thing at which point i removed the i-drive unit to peddle and same results if anything i dont have to do the peddle reset as it just clears when engine is powered off and back on again.Jeep starts fine and drive it, as soon as it has load on engine or steep incline it will throw the red lighting bolt and hesitate slightly i dont give it anymore load on engine and use the lower gear to get up hills at a slow speed. But yes is PIA so thought if better get this issue resolved before it stops all together.
@@matthew9826 I decided to put some time into my problem while waiting for my crank sensor. I discovered the issue in the end it was the pig tail loom that connects the factory harness to the throttle body "Only effects the Jeeps that have the Australian Sprintex super chargers as they supply a pigtail to extend the factory harness as its too short to reach the new location of the throttle body. Any way long story short, Pin 4 was badly oxidized and parted away when i pulled on the wire of that connector after discovering high resistance on pin 4 of the pig tail harness with my fluke voltmeter. So after repairing the harness my issues have completely gone. So now i will have a spare crank sensor when i receive it. Thanks again for your thread as you made me think when u said you had no other warning lights.
@@Icecream_Unicorns Awesome!!! glad to hear you figured it out. Also you might as well hang on to that sensor just in case you have that problem a lot of us are having, you never know it just might come in handy.
Thanks for this. I was just wondering if I needed to unload mine due to this intermittent issue. My daughter wants to take the Jeep to college in the fall and I don't want to send her in something unreliable
It never broke down on me. As for reliability, it was just more of a annoyance, but if you replace that sensor you should be good for at least a couple years or more nothing's made to last anymore unfortunately.
Same thing with my 2013 rubicon 2dr,, 70+000 along with,, leaking Oil Cooler ( bout $1000. , rear wheel sensor and bearing $810.,, loss of coolant, small crack in overflow container $22. And let’s not forget Lil heat issue.! Thank you for info,, Greatly appreciated !!!
@@matthew9826 I never did smell coolant and it never left a puddle but every week the reservoir was dry. Upon inspection, I noticed a coolant residue below reservoir that led to a tiny crack in reservoir. Replaced it and haven’t lost any coolant since.
Changed mine and it's still doing it. Camshaft, crankshaft, throttle body, plugs, wires, coil pack,maf, and I'm still having rpm surge and bogging. Maybe it's the o2 sensors or fuel pump.
You mentioned wires. I thought this was coil to plug, what wires did you change? I know my friend had a wire harness issue but he caused it by getting one of the fuel injection wires pinched when he put his throttle body back on. But he also had a check engine light to help him figure it out.
So when you started pressing your pedal to accelerate, it would bog down a little and then pick back up? That’s what mine does, but not always, which is confusing.
My 2012 Jeep just recently started shutting off at idles and idk what the issue could be. Just did this and hopefully we'll be back on the road today and that fixes it. Regardless the sensor looked old and beat up so it needed to be changed
Is that the feeling i have, where i can be driving and it feels like it falls flat on it's face for a brief second? Been trying to figure it out, thought for sure it had something to do with the drive by wire system in it..
I hope that's my issue! I have had the jerking issue when accelerating. But recently, it will lose power and throw a tc and engine light if I give her the beans...
I just bought a 2023 jeep wrangler willys edition with the 3.6 penstar with etorque. When cruising at 60 to 75 mph in 8th gear with cruise control on it feels as if the jeep has a stutter. It almost feels like it is in high wind where the jeep either lurches forward or has a loss of power, and it is very, very quick . Could this be the same issue? The dealership can't find anything wrong with it.
I have a 2021 gladiator now and I've noticed it myself but it's only happened a couple times to me the couple years I've owned it but the feeling is the same
@@wendull811 you know I really never paid attention. I recall it happening a month back. It was kind of warm but not really hot. If it happens again, I'll definitely pay attention
I have a 2012 3.6. It has about 60,000 miles on it and I've had it for 3 years. It has had a constant drag on the engine on acceleration since I got it, but it's gotten worse. Mine is all the time, not intermittently. It feels like I'm dragging an anchor when I take off from a stop until I get above 1500 rpms. The same thing happens when I'm in a higher gear (it's a six speed manual) and try to accelerate, it just lags. I'm going to try the crank sensor change anyway and see if that does it. Thanks
Sorry for the late reply just saw your comment. Does your Jeep shake like it's missing during your acceleration? I will admit the 1st year of me owning that Jeep I thought it was very underpowered but I just wasn't getting enough RPM'S up, the power band doesn't kick in until around 2500 rpm. I was used to a Turbo sports car before my Jeep lol
What you say makes sense because when it breaks 2500 rpm it comes alive and starts accelerating normally and being more responsive. I have no problems with it in any rom range over 2500.
@@kpfalconi I'm having the same problem. Just ordered the sensor. I hope it fixes it. I have quite a few modifications done in an effort to replace lost HP from extra weight, bigger tires, etc. Then it started to hesitate and lack power in the low RPM range. It absolutely rips about 2500 and up.
I replaced the crank Position sensor and did not fix my issue. Replaced the air temp sensor, MAP sensor, and that didn't fix it. Now, I want to clear the ECM of all codes including relearning all sensors. THAT's what I need to know. One technique on how to clear the ECM and have the engine relearn everything!! Any ideas that really work??
I had the same problem, checked everything, nothing, ordered a new crank position sensor but have to wait for a week so pulled it out gave it a good spray and cleaned it, hasn’t happen again. Thanks for sharing, I was loosing my mind hahaha 🤪
Interesting that Jeep service department said that it was nothing. They are trained to find SOMETHING. And surprised they didn’t tell you they would need to crank off the top and check the camshaft/recommend 1500 for the part and 2200 or so for the labor if it was malfunctioned at the bottom. My jeep kind of had similar problems but my engine light actually came on later and was diagnosed as a cylinder two misfire. Unfortunately for me it wasn’t as simple as coils and plugs. It was pricy!
Yeah I was very upset over the fact that they charged me 2 hours labor for nothing. They basically said we took it out for a test drive over an hour and it never happened, I figured they'd hook up a scan tool to it and probably see something out of the ordinary but guess I was wrong.
The part number on the one show in your hand is different than the one you show installed. Can you let me know what one is correct Thanks for the video.
I no longer have that jeep, but the part I used in the box did work you can go to basically any auto part store and they'll find a sensor for you numbers will probably be different because it's a off-brand.
I have a 2016 Jeep. Today, while I was driving, my entire dashboard started flickering. I pulled over, put it in park, and turned it off. There was a complete loss of power, and nothing was running. About 30 minutes later, the power came back on. Do you think this could solve the issue?
I’ve got a 2018 JL Unlimited Sport with 26,000 miles on the 3.6 engine . I’m getting some hesitation when I put it in drive and then she moves. Some times she jumps. Even some backfiring. When I brake and come to a stop the RPMs drop below 1000 like it’s ready to stall.
@@ChrisMiller-uf7lj not sure usually if this is the issue it fixes itself after the new part is installed. I've heard of a couple people replacing the cam position sensors and fixing the problem as well.
I had this same problem. It turned out to be a kinked fuel line. The jeep ran fine around town, but on the freeway it really struggled to get up to speed and had no passing power and my top speed was 90km per hour.
Yeah sounds like you had a different problem mine did it in town on highway basically whenever it wanted to LOL. But glad to hear you found the problem, nothing worse than having a vehicle fail on you.
I would if I still had the Jeep I just upgraded to a Gladiator Mojave. But I will say they were well worth the money they're definitely not like those Amazon or Ebay lights that blind the hell out of other people they're designed correctly and DOT approved.
I'm coming from a stick YJ and an automatic XJ, BOTH with the 4.0-Liter straight 6. The 3.6 V6 in my stick JT gladiator feels gutless and no torque under 3000 rpm compared to both 4.0-Liters in my YJ and XJ. Is that normal? From 3000 RPM to 6000 RPM the 3.6 makes great top end power. However at about 4000 RPM there feels like a dead spot or flat spot or a weak spot in the acceleration and then after a fraction of a second it begins to accelerate again on through 5000 and 6000 RPM. It doesn't always do this dead spot at 4,000 RPM and when it does do it it's barely detectable but definitely there. Any advice or opinions on what that might or might not be?
Another way to describe how it feels is it's accelerating good from 3000 to 4000 RPM, then the acceleration hits a flat spot at 4000, and then begins accelerating again from 5000 to 6000
Yeah these engines are definitely underpowered before 3000 RPM. As for your problem, I honestly don't know. I don't have that dead spot but maybe check your cam possession sensor.
Did it hesitate starting when it set over night cold mine does that then it’s fine , only when I start it turns over little longer when starting it power seems ok . Just when I start it .
I have a 2015 jk and it randomly dies while im on highway. Radio lights and electronics still on. I coast to a stop, turn it off then it cranks right back up and i can drive again. It never runs sluggish or hesitates the engine just shuts off randomly. So annoying and dangerous. Going to try this. I hope this fixes it.
Thanks for the video! Girlfriend has a 2012 wrangler sport and it was randomly stalling out while she was driving. Did this 3/4 times took it to a shop and they couldn’t figure it out. I then noticed her purge canister had a hole so I replaced it, stalling stopped for a couple weeks. Started back up again and noticed her negative battery terminal was super loose so we replaced that too. Stalling stopped for almost 2 months and has now started up again. Battery/alternator check out okay! And we are just stumped on what it could be. Do you think this could fix it from stalling while it’s driving or could it possibly be something with her fuel pressure?
Honestly that sounds like a different problem. My Jeep never stalled it just hesitated however someone made a comment just recently and they had similar problem to yours and this did fix it. It's only a $20 part and probably wouldn't hurt to try. Best of luck I hope you get it running perfect again.
I Have the exact same issue but its really bad on the highway. I can apply gas and it'll just hit miss hit miss hit miss hesitate, etc until it down shifts, then it still acts up some. Pisses me off cause It just started after warranty expired and the JK only has 24k miles. Love the Jeep but hate the MOPAR BS. I changed my Crans position sensor and it did nothing. SO PISSED.
Sorry it didn't help. It could possibly be a cam position sensor as well. Hard to tell if you're not getting any check engine lights that would definitely be the better route so you can figure it out quicker.
I'm not sure what you mean by hesitation but it sounds similar to what I am experiencing. On my jeep, it will run fine but then out of nowhere, while driving, the lights on the instrument panel will turn on as if I were just turning on the jeep, there's some loss in engine power, and everything will clear out within a second. there are no error codes either. I thought it was probably an electrical issue but the stereo isn't affected when this happens.
@@matthew9826 I think I found what was wrong. the wiring to the battery was super loose. I thought it was supposed to be that way but apparently not, so I tighten things up and hopefully it doesn't happen again. fingers crossed!
Will this fix any issue with the car not wanting to accelerate at highway speeds? Usually have to punch it to get it going once cruising at about 60mph. After the first hard acceleration seem to be fine, not sure if it’s just the fly by wire lagging or this sensor …
I've heard of people having similar issues like yours and this fixing it, but I honestly don't know. I'd at least give it a try though. Best of luck. I hope you get your ride running properly again.
I have a '13 JK and haven't had that problem, but I used to have a 5 speed Ford Focus (it was a good little car) that had that "hiccup". I wonder if this was the problem. We'll never know. Question: should I bother to change this sensor if I don't have the problem in my Jeep? Or, do you think it's only a matter of time? I'm approaching 90k miles. Great video.
If you're not having any issues right now, I wouldn't worry about it; you probably just got lucky with a good sensor. However, if you start feeling hiccups once-a-month, yeah, go ahead and change it out before it turns into a headache.
@@ang2702per Probably not, sounds like an oxygen sensor issue. But if you've tried replacing that already it probably wouldn't hurt trying this sensor as well. Who knows, maybe it's freaking the PCM out.
Mine has been doin this for about a week now,, Transmission shop has called twice , says they cant duplicate the problem,, Ive changed the CAM SHAFT sensor at least twice allready. Wondering if its somn else, But for the sake of gettin my jeep back this weekend ,, Ima change that Bish AGAIN and see what happens. but the problem it would lurge forward and Id feel a bump in the rear ,, then No Acceleration No Power nothing , Id have to pull over shut down shift to park,, then restart and its Fine,, untill the next day,,, Lawd ha Mercy Im bout to Push this thing off a CLiff!!
My wife’s 2013 isn’t doing that but it suddenly loses power steering and the gas pedal doesn’t work at all. You have to pullover and turn the jeep off and back on and it’s fine. You think changing the CPS will fix it? Or am I having a different issue? I’ve looked all over and have seen others with the same issue but no apparent fix.
With your power steering pump going off intermittently, I'd at least checked the serpentine belt and fluid. It's not electric to my knowledge and hooked up to the serpentine belt. As for the gas pedal, that's hard to tell. The drive-by wire might be compromised somewhere or the pedal sensor needs replaced. I'd start by checking the plug going into the gas pedal and throttle body seeing if they are fully plugged in. These are just things I would check. Definitely consult a mechanic if you don't feel comfortable doing that.
@@matthew9826 my first thought was the belt too but it’s fine every time I’ve checked. Brought it to a mechanic and he couldn’t find anything wrong. I guess it can’t hurt to give it a shot. Thanks for your input!
I was in cruise control doing about 80 and it lost power like it was bogging out. Turned off my cruise and it doesn't do it accelerating slowly but I does if I floor it.
how many miles are on your jeep, and have you had any check engine lights? I hear changing the cam position sensor fixed a similar issue, but you may just need new spark plugs if you have over 100000 miles on them.
i actually keep these extra sensors in my jeep, i have a crankshaft one, camshaft and extra speed sensors just in case, but i havent had any issues with mine, and she is at 104000 miles and drives stong.
this is good to know. I have a 2014 with 110k miles and have noticed not so much a hesitation, but a bit of a hiccup/jerkiness to the acceleration, but it's really minor for now and I think it's improved since i changed out the old air filter recently. gonna monitor it to see if it's related (already replaced the spark plugs and trans fluid). these jeeps do have quirks. really have to follow the maintenance to a tee in order to keep them running properly.
My Jeep started stalling when putting it in reverse after start up. The second start always took care of it. It happened the other day after driving a bit and going into reverse. I had to rev the rpms to keep it from stalling. It seemed to work it out and now good. Did you experience this?
Did it feel like it was bucking like the gears were slipping mine done it at highway speeds but mine shut down wouldn’t start back until about it set for 10 min
@@jakenoll8656 if you have a check engine light I'd get that checked out. You could probably have something completely different like your mass, airflow sensor or something else
Changed mine out on my 2012, 2 weeks later did it again. Took it to mechanic, plug had a broke wire and also one wire was broke at steering column. $600 later…..
Changed mine on my 2013 yrs ago..$16 part..dealer didn't even know what CPS was..tried to tell me my computer was fried..went to a couple jeep forums.found the fix..Love my Jeep ppl
Thank you for putting this on RUclips. I too had a similar problem with my wife's 2013 Jeep. Had the same problem for about 1 and 1/2 years, took it to a Jeep dealer and spent a lot of money and they could not fix it. I did what you suggested and the Jeep drives like a new vehicle. I'm even getting about 3 more miles per gallon. I rarely comment on social media. I just wanted to say Thank You for taking the time and posting the solution!
You're welcome. I'm happy to hear this video helped you!
SAVED me a fortune..... three dealerships failed to diagnose....... THANK YOU!!!!
No problem glad I could help.
Bingo! Same thing happened to my 2016 Jeep just was not running great and it finally pulled a code and check engine light came on…it was the Crank Position Sensor and called NAPA and they said they had one in stock. I bought it and changed it with like one bolt holding it on and drove it the next morning…OMG…it was like a new car…fun, quick, responsive again and me very happy!!!
Dude!!! You just save me so much time and energy thank you for taking the time out of your day to help the rest of us!
Glad to help.
Matt I was wondering if you had an issue when you snapped the throttle quick if it would choke out before revving up? Was looking at an 18 Jeep for my daughter the other day and I was doing that when I started it at the dealer. Thanks for any input.
@hd100thjd Yesss just did mine today. It would choke out then lunge forward like I had NOS 😂 try to get it for cheap and hope thats it.
For me it was around 40mph 3rd gear i think. 2012 wrangler
@@matthew9826 Just brought a 2018 JK 3.6 3 weeks ago. My only issue is I feel it’s slow or doesn’t come out the gate running fast like I have to floor it to get up to 55/65 Mph. The dealership says it’s fine. So my question is would the CPS help far as speed or horsepower? Help
@@tellyjones2434 Honestly, these engines are underpowered. The torque doesn't kick in until like 3500 4000, RPM. I thought the same thing when I bought mine new. I just started shifting later rather than sooner. I'm assuming you have a manual?
I have a 2012 RUBI having the exact same issue and of course no codes to help diagnose the cause. This is a manual which would jerk me around with every hiccup. With almost 155K on the clock thought it was fuel pump related. Read on line about the crankshaft position sensor so changed it yesterday. So far so good. Thinking of also changing the camshaft sensors which might be overkill but with my current mileage might not hurt. Glad your is fixed and hopefully hasn't had any more issues.
Well kind sir, 3 years later I watched your short video and indeed it made my day. My '13 Town & Country has a new genuine Mopar CPS and it hasn't run this well in 18 months. Dealer couldn't figure it out - similar story to many commenters here. Many thanks for leveraging what you learned by showing us all what it takes.
You're welcome! I am very happy to hear this video helped you out!!
This video made my day. Have the same 2013 Jeep, and had the same problem. Also frustrated me for a little over a year. Started so infrequently I thought it might be a transmission issue so got a flush, nope. Then a new air filter, nope. Then a dealer guy drove it, no luck. How about a new MAP sensor, nah. Finally found this vid down a rabbit hole that began when I started using the adjective “hiccup” to describe the feeling in acceleration. Got the part, installed and the Jeep feels brand new. I can’t believe how easy that was to fix and how hard it was to figure out. Hell yeah. Thank you. I was about at my wits end ;)
Glad to help thanks for letting me know! I still can't believe dealerships still don't know anything about this issue.
I've been trying to figure out this issue with my 2012 wrangler! Since you changed the crankshaft have you had the stalling issue at all? I'm at 180,000 km
Update!! Mines a 2013 with almost 42,000 miles. I put a comment on here about an hour or so ago. I went right down to O’reilly and they had ONE in stock. Here’s to hoping that’s my issue. Thanks again brother.
Thank you for the video!!! My 2015 Jeep Wrangler unlimited at highway speeds lost power and had the RPMs go to 0 for a split second and would regain power and be fine for several days before doing it again. This happened four times to me. I was telling my dad about it at Christmas yesterday, he said, “it might be your crank sensor”. Well, thanks to my phone listening in on our conversation that night, I was scrolling down my RUclips feed and found your video, 3rd video down. And thought what the hell, I’ll try it for $20. Today the jeep ran great, I picked up the sensor at O’Reilly’s, went to the gym. When I was leaving the gym, for the first time the Jeep starting running like shit and had no power. Misfiring and finally threw a code and what do you know it was the crank position sensor. I changed the sensor and cleared the code in the McDonald’s parking lot and the Jeep ran like new on the way home. Thank you again for taking the time to make the video!
Happy to help, and glad to hear it fixed your problem!
Just bought my Jeep. Yeah, had high miles, so i didn't expect perfection- but I am retired E.O.D. - so not about to tolerate any BS.
Anyway, I am jazzed to see this vid ! Tomorrow will switch it out !
Thanks!
Wulfy OG
I’ve replaced almost every sensor and was about to replace the throttlebody because of hesitation and power loss and tomorrow I was going to pull out the TIPM and replace it. I’m gonna try your trick and I hope it saves me a lot of money and frustration. Thank you.
So what happened? Did you try it ?
Thank you for this info. My 2013 started having this issue, stuttering on acceleration, and once it even lost all power while driving. Though after 15 minutes, I was able to start back up and continue on my way. No codes ever showed up. I bought the crank position sensor within minutes of watching this video, and replaced it myself. Solved the problem immediately.
Tip: wait at least an hour after driving to replace the sensor. Everything down there gets real hot!
AMEN !! same symptoms... 2015 JKU Sport. Suddenly no throttle, RPMs dropped to 0 periodically, then comes back. Gradually started stalling too. Within a week I found this post. Replaced the sensor in 10 minutes. Problem gone. THANK YOU !
No problem glad to help.
I miss diagnosed a vw jetta and I changed the crank sensor and it gained more power too. From my experience i always thought the crank sensor ether works or doesn't now i became a believer. And it still doesn't make sense.
Agreed, maybe it has something to do with this style sensor. All the sensors I've changed in the past just straight up failed but they were also on the outside of the engine.
@@matthew9826 the only thing I remember when I changed it the plug on the outside was soaked in oil and I cleaned it before I installed the new crank sensor. Maybe that also had to do something with it.
Had the same problem a few years back. I did take it to the dealership with same response. Took it home bought the part and replace it in 15 minutes. Problem resolved.
By the way mine was shutting off while driving from a stand still and it would love to do it in intersections.
Dude, exactly the same experience. Still doing it after changing
Thank you very much! I changed the spark-plugs several months ago because of this issue at 60K miles 2012 Rubicon, but the issue continued. Just replaced the sensor and I am going for a 40 miles ride and hope the problem is solved. One thing I noticed was that the rubber seal from the old part was flat compared to the new one which makes me wonder. Thanks again!
Same thing started happening to me. At first it was like my engine shutoff really fast for like a second then kicked back on. Then it started happening until it shut off on me at a red light, at a stop light and almost put me on the side of the highway.
It turned the engine off and left my electrical on., didnt throw any codes as well. Started happening to me around 190 thousand miles.
Currentmy have 242k on mine.
It was the crankshaft position sensor. Had the same issue one time on a grand cherokee yrs ago .
Glad u got ur figured out and fixes
I had one of them go on my 2015 Rubicon on same engine. Scan tool told me which one to change. My symptom was traction lock light would come on over 75Mph, which would lock up rear brakes which Jeep simply overpowered. I had to turn off traction control from switch and when I stopped, smelled the bakes burning. It would also throw the check engine light. Once crankshaft sensor replaced.. all fixed. Occasionally I got EVAP check engine light on also, that has gone away also since changing this crank shaft sensor so maybe it was all related and threw codes being on same BUS network.
Just changed one on a 2013 Jeep Grand Cherokee with about 75k miles. Worked perfectly! No CEL but it would jerk while accelerating at lower speeds. Thank you for this video!!
@@RudeGarage13 happy to help!
Same exact issue with my '14. Could not figure it out for the longest time and got so annoyed and pissed. Fixed my hesitation problem and I think it even shifts nicer as well. Thanks for the help and heads up.
I'm glad to hear this video helped. Thanks for the comment!
Just hit 250K and my 2012 is doing the same now at least twice a week and shutting down. I just changed mine, 10 min tops, and fingers are crossed. Thanks!
Well? Did it work?🤔

$20 instead of $500.....I feel like an idiot.
@@brianlackey3834Awesome! I hope this definitely fixes your issue. It seems like even the dealerships still haven't caught on to this. There's still people taking their Jeeps to the dealer and they're saying nothing's wrong with it.
@matthew9826 I believe you. That's why I call them "Stealership's."
Still can't believe I wasted $500 on a valve body swap. Good thing I did it myself or I would have wasted over 1K.
Thanks again brother!
I changed my camshaft position sensor and crankshaft position sensor at the same time. I have a newer Jeep and it was not in an easily accessible location as yours but it was still cheaper than taking it in to the shop
Thank you so much for sharing this! My 2012 just had this happen at 162,000 miles. My son and I changed the part in about 5 minutes.
Glad to help
bruh, this is my issue, guaranteed. I am just under 50k miles on a 2015 JK and this sudden loss of power "for a second" thing just started happening to me after I shipped my vehicle from Hawaii to San Diego. One quick YT search and here I am. Thanks.
No problem, happy to help.
I’m encountering a very similar issue with my 2015, gonna try this fix and see what happens!
Can't wait to try this on my 2012. Dealer said it was an oil gallery plug and that repair did nothing. Same symptoms: stalling on initial acceleration, stalling when in 6th gear at 60+mph, cruise control canceling when it stalls, no error codes, los of oil pressure when it happens. Thank you!
I hope this fixes it for you.
@@matthew9826 amazing, I went to auto zone, picked up a duralast crank position sensor for
@@isthereafeeforthis Awesome!!! I'm happy to hear this fixed it for you. Unfortunately you're not the only one that went to a dealer and they told you there was nothing wrong or something else. It happened to me and a couple other people in the comments, it's kinda sad and seems to be a common issue I don't understand how they don't know this is the problem.
I have an issue on a child start. When placing my on the brake and shifting from park to reverse I will get hesitation with it occasionally stalling. Once the Jeep is up to temp, I don't have any issues.
Could be related, but I honestly don't know. I had a 6-speed manual, and automatics can act up from time to time
@@matthew9826 thanks, I'm afraid that it may be the torque converter.
@Mark Deluisi yeah that kind of does sound like the torque converter, but the part I was talking about only costs around 20 bucks. I'd go ahead and give that a shot. Maybe it'll fix your problem, and if not, it was only twenty bucks.
@Mark Deluisi good luck, though. I hope you figure out what's going on and get your jeep running properly again.
@@matthew9826 I'm going to try that part. Thanks
Bro, switched out crank position sensor, worked like a charm , right away. Thanks for the info...
Awesome!! glad to help
Absolutely crazy!! My girlfriends 2014 rubicon has been doing this, just going down the road and it suddenly loses power like it's starving for fuel then dies. Wait a few minutes and it starts right up like nothing happened and maybe 2-3 month later it happens again, no codes or any real sign of a problem. Very intermittent, definitely worth throw a cheap part at it and see if that will resolve the issues. Thank you for posting
Hopefully this works for you. Definitely let me know if that ends up fixing it.
@@matthew9826 So I picked up the part and went under the jeep only to find the bolt that holds it in is snapped off so obviously this part has been changed before so now I'll have to figure out how I'm going to drill it out in a tight space before I can replace the part.
@@tomfoolery8640 dang how was it even staying in with the bolt broke off? Heck that could actually be your issue right there with the sensor not being fully seated
@@matthew9826 looks like they use form a gasket or gasket sealer to hold it into place, I'm hoping when i take out the sensor there will be enough of a nub to work with as far as extracting the remaining part of the bolt. still i know this is going to be a hold your breath and hope for the best.
Thanks a lot....I have the same symptoms on my 2013 jk....I will change the cranck sensor and hopefully it works....I been dealing with this problem for a long time and also the dealership has not been able to fixed it but they sure charge for their time waisted.
Happy to help! I hope this fixes your issue.
Thanks brotha, that was exactly what was wrong with my Jeep. Bought the part and just like you said, five minutes and the problem solved. (Jeeping in the USVI)
Awesome! Glad to hear this helped
What's the name of the part? I tried to find it on ebay or other stores but I can't find it 😪
I just replaced my camshaft sensor, didn't help. I think you just helped me. I'll replace the part tomorrow. Thanks
Same!
Dude thank you so much. I'm so stoked my jeep is back and no more bucken and jerken. It was so annoying.
Awesome glad to help!
Hoping this is my issue. Going to pop one in later today.
Put the new one in and no immediate changes yet. Its slightly better but the issue is still there. Im hoping i just need to give it time. Ill see how it drives home from work tonight.
Is it working fine now ?
I’m Trying this method ! I recently got 2016 Jeep Wrangler Stick shift , started having problems Not being able to turn on . Dealerships couldn’t figure out said it was PCM , changed a new one . Now it’s a ‘ Tipsdip ‘ line that runs to the PCM . Anyhow Now it turns on fine , but on the freeway my Jeep started to pull foward on first gear and barely getting second gear . ( after I was bumper to bumper on a 99 degree hot weather ) So Now I’m trying this Method . Hopefully this can Actually fix the Jeep . Thanks
I’m encountering the same problem. Have changed plugs. Just quit on the way home. I’m going to swap this part next. Thank you
Did it work
@@huntermills4192 it’s funny that you ask.
Since I replaced this part, I have had not one issue!!!!!!!
Also wanted to add, this fix improved my mpg by 5... wow!
That's awesome!
Mine went bad around 90k miles and I was pretty sure the CPS was the problem but like you, it wouldn't throw a code. I drove it for a bit longer and it slowly got worse, eventually it threw a code and then the dealer fixed it under warranty. Knowing what I know now, I'd just fixed it myself and sooner. It's lame that it takes so long for it to trigger the code.
Thanks for the help.. I easily replaced mine with this video… haven’t had it stall yet so I’m crossing my fingers this solves my problem.
You're welcome. I hope this works for you
I got a 2012 had the same issue but my did through a intermittent crankshaft sensor code strange how it didn’t for u
I hope this is the fix for what I believe is the same issue. Over the las week while on the freeway my Jeep would fluctuate in speed. The ABS light would come on along with the battery light for a split second. The Speedometer would drop from current speed of 60/65 down to 40 mph and then back. Meanwhile I felt a loss of power even with my foot hammered down on the gas pedal. No Codes show on the dash. I turned around to go back home and maintained speed of 60mph with no issues. Off to Riley's for a Crankshaft Sensor.
Good luck I hope it fixes the problem for you
Hopefully thats what my issue is, i have ordered the part and just waiting now. Only had just done 60,000Kms started about a 1.5years ago when in crusie control and it cancelled out of it and showed the red lighting bolt and would surge forward under its own power on throttle. No engine codes ever. Pulled over did the google mechanic thing and did the throttle peddle reset and drove on. Didnt saw the issue again untill 6months, same issue fixed it with peddle reset. Then became monthly and then once ever week and became daily thing at which point i removed the i-drive unit to peddle and same results if anything i dont have to do the peddle reset as it just clears when engine is powered off and back on again.Jeep starts fine and drive it, as soon as it has load on engine or steep incline it will throw the red lighting bolt and hesitate slightly i dont give it anymore load on engine and use the lower gear to get up hills at a slow speed. But yes is PIA so thought if better get this issue resolved before it stops all together.
Interesting. I never got the lightning bolt, but hopefully this will fix your problem.
@@matthew9826 thxs for super quick reply. Will let u know if it resolves it once i have the part 🙏🙏
@@matthew9826 I decided to put some time into my problem while waiting for my crank sensor. I discovered the issue in the end it was the pig tail loom that connects the factory harness to the throttle body "Only effects the Jeeps that have the Australian Sprintex super chargers as they supply a pigtail to extend the factory harness as its too short to reach the new location of the throttle body. Any way long story short, Pin 4 was badly oxidized and parted away when i pulled on the wire of that connector after discovering high resistance on pin 4 of the pig tail harness with my fluke voltmeter. So after repairing the harness my issues have completely gone. So now i will have a spare crank sensor when i receive it. Thanks again for your thread as you made me think when u said you had no other warning lights.
@@Icecream_Unicorns Awesome!!! glad to hear you figured it out. Also you might as well hang on to that sensor just in case you have that problem a lot of us are having, you never know it just might come in handy.
Thanks for this. I was just wondering if I needed to unload mine due to this intermittent issue. My daughter wants to take the Jeep to college in the fall and I don't want to send her in something unreliable
It never broke down on me. As for reliability, it was just more of a annoyance, but if you replace that sensor you should be good for at least a couple years or more nothing's made to last anymore unfortunately.
@@matthew9826 I changed it and it didn't fix the issue. What's next? O2 sensor?
@@unicornsteaks6769 I honestly don't know. My issue was fixed by replacing the crank position sensor. Maybe check your cam position sensor.
Same thing with my 2013 rubicon 2dr,, 70+000 along with,, leaking Oil Cooler ( bout $1000. , rear wheel sensor and bearing $810.,, loss of coolant, small crack in overflow container $22. And let’s not forget Lil heat issue.! Thank you for info,, Greatly appreciated !!!
Mine had a coolant smell for quite a while but it doesn't leave any coolant on the ground I wonder if it was the reservoir LOL
@@matthew9826 check the thermostat. Ours had a small crack in it and it would leak down over time.
@@matthew9826 I never did smell coolant and it never left a puddle but every week the reservoir was dry. Upon inspection, I noticed a coolant residue below reservoir that led to a tiny crack in reservoir. Replaced it and haven’t lost any coolant since.
Changed mine and it's still doing it. Camshaft, crankshaft, throttle body, plugs, wires, coil pack,maf, and I'm still having rpm surge and bogging. Maybe it's the o2 sensors or fuel pump.
You mentioned wires. I thought this was coil to plug, what wires did you change? I know my friend had a wire harness issue but he caused it by getting one of the fuel injection wires pinched when he put his throttle body back on. But he also had a check engine light to help him figure it out.
So when you started pressing your pedal to accelerate, it would bog down a little and then pick back up? That’s what mine does, but not always, which is confusing.
It was usually when I was already moving but yea it did that to me every now and then as well.
Just paid 1000 for a new computer in my 2012 wrangler… still has the same issue, I’m changing my cps hopefully that fixes the issue
I replaced the crankshaft sensor and it fixed it. I had no codes showing up.
Awesome!!!
I hope this works
My 2012 Jeep just recently started shutting off at idles and idk what the issue could be. Just did this and hopefully we'll be back on the road today and that fixes it. Regardless the sensor looked old and beat up so it needed to be changed
Did you fixed the issue with your 2012 jeep? Any additional symptoms. I have one that does not wants to start and at 3rd attempt it runs.
@Daniel Medrano it fixed my issue. I has the problem with starting it nefore but that was just the battery I believe.
Is that the feeling i have, where i can be driving and it feels like it falls flat on it's face for a brief second?
Been trying to figure it out, thought for sure it had something to do with the drive by wire system in it..
Yep that sounds exactly like what mine was doing.
I hope that's my issue! I have had the jerking issue when accelerating. But recently, it will lose power and throw a tc and engine light if I give her the beans...
I just bought a 2023 jeep wrangler willys edition with the 3.6 penstar with etorque. When cruising at 60 to 75 mph in 8th gear with cruise control on it feels as if the jeep has a stutter. It almost feels like it is in high wind where the jeep either lurches forward or has a loss of power, and it is very, very quick . Could this be the same issue? The dealership can't find anything wrong with it.
I have a 2021 gladiator now and I've noticed it myself but it's only happened a couple times to me the couple years I've owned it but the feeling is the same
@matthew9826 just out of curiosity, was it a long drive or a really hot day?
@@wendull811 you know I really never paid attention. I recall it happening a month back. It was kind of warm but not really hot. If it happens again, I'll definitely pay attention
I have a 2012 3.6. It has about 60,000 miles on it and I've had it for 3 years. It has had a constant drag on the engine on acceleration since I got it, but it's gotten worse. Mine is all the time, not intermittently. It feels like I'm dragging an anchor when I take off from a stop until I get above 1500 rpms. The same thing happens when I'm in a higher gear (it's a six speed manual) and try to accelerate, it just lags. I'm going to try the crank sensor change anyway and see if that does it. Thanks
Did it work on your manual? I have one too and am curious to see what results you saw. Thanks.
Sorry for the late reply just saw your comment. Does your Jeep shake like it's missing during your acceleration? I will admit the 1st year of me owning that Jeep I thought it was very underpowered but I just wasn't getting enough RPM'S up, the power band doesn't kick in until around 2500 rpm. I was used to a Turbo sports car before my Jeep lol
What you say makes sense because when it breaks 2500 rpm it comes alive and starts accelerating normally and being more responsive. I have no problems with it in any rom range over 2500.
@@kpfalconi I'm having the same problem. Just ordered the sensor. I hope it fixes it. I have quite a few modifications done in an effort to replace lost HP from extra weight, bigger tires, etc. Then it started to hesitate and lack power in the low RPM range. It absolutely rips about 2500 and up.
I replaced the crank Position sensor and did not fix my issue. Replaced the air temp sensor, MAP sensor, and that didn't fix it. Now, I want to clear the ECM of all codes including relearning all sensors. THAT's what I need to know. One technique on how to clear the ECM and have the engine relearn everything!! Any ideas that really work??
When it comes to the ECM, I don't know much about it. As for the crank position sensor, there's no relearning for it. Its just plug and play.
I had the same problem, checked everything, nothing, ordered a new crank position sensor but have to wait for a week so pulled it out gave it a good spray and cleaned it, hasn’t happen again. Thanks for sharing, I was loosing my mind hahaha 🤪
There you go spoke too soon, gave it a clean but didn’t work for long problem back just wait for this part to come, ill let ya know if it works...
@@waynemoore7415was that able to be resolved?
Interesting that Jeep service department said that it was nothing. They are trained to find SOMETHING. And surprised they didn’t tell you they would need to crank off the top and check the camshaft/recommend 1500 for the part and 2200 or so for the labor if it was malfunctioned at the bottom. My jeep kind of had similar problems but my engine light actually came on later and was diagnosed as a cylinder two misfire. Unfortunately for me it wasn’t as simple as coils and plugs. It was pricy!
Yeah I was very upset over the fact that they charged me 2 hours labor for nothing. They basically said we took it out for a test drive over an hour and it never happened, I figured they'd hook up a scan tool to it and probably see something out of the ordinary but guess I was wrong.
@@matthew9826 Ughh! of course it never happens when we bring it to the mechanic! Like your vid! 🤙
The part number on the one show in your hand is different than the one you show installed. Can you let me know what one is correct
Thanks for the video.
I no longer have that jeep, but the part I used in the box did work you can go to basically any auto part store and they'll find a sensor for you numbers will probably be different because it's a off-brand.
Hey did that stay working just put a new crank position sensor took it for a test drive but my eco mode keeps showing just wondering
The sensor fixed my problem for a year before it was sold. I don't recall the eco staying on though.
I have a 2016 Jeep. Today, while I was driving, my entire dashboard started flickering. I pulled over, put it in park, and turned it off. There was a complete loss of power, and nothing was running. About 30 minutes later, the power came back on. Do you think this could solve the issue?

I’ve got a 2018 JL Unlimited Sport with 26,000 miles on the 3.6 engine . I’m getting some hesitation when I put it in drive and then she moves. Some times she jumps. Even some backfiring. When I brake and come to a stop the RPMs drop below 1000 like it’s ready to stall.
It may be the same problem.
I did that to mine 2013, and it still sputtering! Does it need to have a comper reset
@@ChrisMiller-uf7lj not sure usually if this is the issue it fixes itself after the new part is installed. I've heard of a couple people replacing the cam position sensors and fixing the problem as well.
I had this same problem. It turned out to be a kinked fuel line. The jeep ran fine around town, but on the freeway it really struggled to get up to speed and had no passing power and my top speed was 90km per hour.
Yeah sounds like you had a different problem mine did it in town on highway basically whenever it wanted to LOL. But glad to hear you found the problem, nothing worse than having a vehicle fail on you.
How did you fix it ?
And where it was
How bout a review on the kc hilites.
I would if I still had the Jeep I just upgraded to a Gladiator Mojave. But I will say they were well worth the money they're definitely not like those Amazon or Ebay lights that blind the hell out of other people they're designed correctly and DOT approved.
Thank you you saved me time and money right before a roadtrip so much appreciated
Awesome glad to help!
@matthew Armstrong will this make it feel kinda like your transmission? I was at 20 mph and felt like it wouldn’t go
Is yours an automatic? If so I'm not sure how it feels with that. I had a 6 speed manual and it just felt like engine power loss.
I'm try it. Because I'm thinking fuel pump engine but jeep cranks right up. Just when I'm driving 🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼
I'm coming from a stick YJ and an automatic XJ, BOTH with the 4.0-Liter straight 6. The 3.6 V6 in my stick JT gladiator feels gutless and no torque under 3000 rpm compared to both 4.0-Liters in my YJ and XJ. Is that normal? From 3000 RPM to 6000 RPM the 3.6 makes great top end power. However at about 4000 RPM there feels like a dead spot or flat spot or a weak spot in the acceleration and then after a fraction of a second it begins to accelerate again on through 5000 and 6000 RPM. It doesn't always do this dead spot at 4,000 RPM and when it does do it it's barely detectable but definitely there. Any advice or opinions on what that might or might not be?
Another way to describe how it feels is it's accelerating good from 3000 to 4000 RPM, then the acceleration hits a flat spot at 4000, and then begins accelerating again from 5000 to 6000
Yeah these engines are definitely underpowered before 3000 RPM. As for your problem, I honestly don't know. I don't have that dead spot but maybe check your cam possession sensor.
Did it hesitate starting when it set over night cold mine does that then it’s fine , only when I start it turns over little longer when starting it power seems ok . Just when I start it .
I didn't see a pattern with the weather it was just random
But it did hesitate starting
@@robglee1512 no it didn't
I have a 2015 jk and it randomly dies while im on highway. Radio lights and electronics still on. I coast to a stop, turn it off then it cranks right back up and i can drive again. It never runs sluggish or hesitates the engine just shuts off randomly. So annoying and dangerous. Going to try this. I hope this fixes it.
@@psychwardfpv4353🤞 but if this doesn't fix it, I'd look into getting your ignition checked.
Thanks for the video! Girlfriend has a 2012 wrangler sport and it was randomly stalling out while she was driving. Did this 3/4 times took it to a shop and they couldn’t figure it out. I then noticed her purge canister had a hole so I replaced it, stalling stopped for a couple weeks. Started back up again and noticed her negative battery terminal was super loose so we replaced that too. Stalling stopped for almost 2 months and has now started up again. Battery/alternator check out okay! And we are just stumped on what it could be. Do you think this could fix it from stalling while it’s driving or could it possibly be something with her fuel pressure?
Honestly that sounds like a different problem. My Jeep never stalled it just hesitated however someone made a comment just recently and they had similar problem to yours and this did fix it. It's only a $20 part and probably wouldn't hurt to try. Best of luck I hope you get it running perfect again.
@@matthew9826 good to hear! We ended up replacing it and so far so good been about 2 weeks now so we’ve got our fingers crossed 👌🏼
@@jabberboxjake2809
Awesome!!! Glad to hear. I hope it for sure fixes your problem, nothing better than a $20 fix.
Thanks for the information because my wife's jk is doing the same thing, on my way to O'Reilly now. Thank you
Happy to help! I hope this fixes your problem.
@matthew9826 thanks, I'll keep you posted
I Have the exact same issue but its really bad on the highway. I can apply gas and it'll just hit miss hit miss hit miss hesitate, etc until it down shifts, then it still acts up some. Pisses me off cause It just started after warranty expired and the JK only has 24k miles. Love the Jeep but hate the MOPAR BS. I changed my Crans position sensor and it did nothing. SO PISSED.
Sorry it didn't help. It could possibly be a cam position sensor as well. Hard to tell if you're not getting any check engine lights that would definitely be the better route so you can figure it out quicker.
Question plz what’s the part name I need to buy ?
Crank position sensor
@@matthew9826 i can’t thank you enough respect all the way .
@Youssef Laabichi thanks, I hope this fixes your problem.
How long to change Trany oil on my 2015 jeep rubicon with synthetic tranny oil I have 67,000 miles?
Thanks for making this. Going to change mine today.
I'm not sure what you mean by hesitation but it sounds similar to what I am experiencing. On my jeep, it will run fine but then out of nowhere, while driving, the lights on the instrument panel will turn on as if I were just turning on the jeep, there's some loss in engine power, and everything will clear out within a second. there are no error codes either. I thought it was probably an electrical issue but the stereo isn't affected when this happens.
No I didn't have any issues like that but I have heard of that problem before maybe someone will comment and help you out with that.
@@matthew9826 I think I found what was wrong. the wiring to the battery was super loose. I thought it was supposed to be that way but apparently not, so I tighten things up and hopefully it doesn't happen again. fingers crossed!
@@mrlovespread2006 oh yeah a loose electrical connection can cause all kinds of problems hopefully that fixes it for you.
Will this fix any issue with the car not wanting to accelerate at highway speeds? Usually have to punch it to get it going once cruising at about 60mph. After the first hard acceleration seem to be fine, not sure if it’s just the fly by wire lagging or this sensor …
I've heard of people having similar issues like yours and this fixing it, but I honestly don't know. I'd at least give it a try though. Best of luck. I hope you get your ride running properly again.
I have a '13 JK and haven't had that problem, but I used to have a 5 speed Ford Focus (it was a good little car) that had that "hiccup". I wonder if this was the problem. We'll never know. Question: should I bother to change this sensor if I don't have the problem in my Jeep? Or, do you think it's only a matter of time? I'm approaching 90k miles. Great video.
If you're not having any issues right now, I wouldn't worry about it; you probably just got lucky with a good sensor. However, if you start feeling hiccups once-a-month, yeah, go ahead and change it out before it turns into a headache.
@@matthew9826 you think engine light on and code p1129 is for this sensor my friend?
@@ang2702per Probably not, sounds like an oxygen sensor issue. But if you've tried replacing that already it probably wouldn't hurt trying this sensor as well. Who knows, maybe it's freaking the PCM out.
Mine has been doin this for about a week now,, Transmission shop has called twice , says they cant duplicate the problem,, Ive changed the CAM SHAFT sensor at least twice allready. Wondering if its somn else, But for the sake of gettin my jeep back this weekend ,, Ima change that Bish AGAIN and see what happens. but the problem it would lurge forward and Id feel a bump in the rear ,, then No Acceleration No Power nothing , Id have to pull over shut down shift to park,, then restart and its Fine,, untill the next day,,, Lawd ha Mercy Im bout to Push this thing off a CLiff!!
Not sure about the cam sensor but try changing the crank position sensor like in this video i bet it will work.
@@matthew9826
My apologies. I MEANT the crank position.
Hope this is the key
Let ya know in a few
My wife’s 2013 isn’t doing that but it suddenly loses power steering and the gas pedal doesn’t work at all. You have to pullover and turn the jeep off and back on and it’s fine. You think changing the CPS will fix it? Or am I having a different issue? I’ve looked all over and have seen others with the same issue but no apparent fix.
With your power steering pump going off intermittently, I'd at least checked the serpentine belt and fluid. It's not electric to my knowledge and hooked up to the serpentine belt. As for the gas pedal, that's hard to tell. The drive-by wire might be compromised somewhere or the pedal sensor needs replaced. I'd start by checking the plug going into the gas pedal and throttle body seeing if they are fully plugged in. These are just things I would check. Definitely consult a mechanic if you don't feel comfortable doing that.
@@matthew9826 my first thought was the belt too but it’s fine every time I’ve checked. Brought it to a mechanic and he couldn’t find anything wrong. I guess it can’t hurt to give it a shot. Thanks for your input!
I was in cruise control doing about 80 and it lost power like it was bogging out. Turned off my cruise and it doesn't do it accelerating slowly but I does if I floor it.
Does that sound like what yours was doing?
@@awhughes63 You may want to check your fuel pressure.
I’ve had the same problem especially when I floor it.
Sorry for the late reply but no I wasn't having symptoms like that.
I am still having issues even after replacing the crankshaft sensor on my Jeep Wrangler 2013 😭😭
how many miles are on your jeep, and have you had any check engine lights? I hear changing the cam position sensor fixed a similar issue, but you may just need new spark plugs if you have over 100000 miles on them.
i actually keep these extra sensors in my jeep, i have a crankshaft one, camshaft and extra speed sensors just in case, but i havent had any issues with mine, and she is at 104000 miles and drives stong.
Very good idea to keep them on hand.
Thank you so much it worked on mine. It literally took me 10 minutes to do.
No problem glad to hear it worked for you!
I had the same problem. Cause was driving over too much water
Was it popping and backfiring at all? Mine is on my 2013. It just started doing it tonight.
No nothing like that
this is good to know. I have a 2014 with 110k miles and have noticed not so much a hesitation, but a bit of a hiccup/jerkiness to the acceleration, but it's really minor for now and I think it's improved since i changed out the old air filter recently. gonna monitor it to see if it's related (already replaced the spark plugs and trans fluid). these jeeps do have quirks. really have to follow the maintenance to a tee in order to keep them running properly.
My Jeep started stalling when putting it in reverse after start up. The second start always took care of it. It happened the other day after driving a bit and going into reverse. I had to rev the rpms to keep it from stalling. It seemed to work it out and now good. Did you experience this?
No, it was only when already in motion. Rarely did it happen going slower than 10 mph. However, this issue may affect each engine differently.
@@matthew9826thank you. I swapped it out yesterday and hoping it helps.
At that cost and easy, it is worth the try.
Hey! Great video. I’m about to try this. Does it spill a lot of oil when changing?
I don't think so, but it's been a while lol. sorry for the late reply.
I just did it. Outside of a tiny drop of oil no issues here! Thanks for the video. You brought new life to my 120k mile jeep!
@@memebandit Awesome! I'm happy to hear that fixed your Jeep
Did it feel like it was bucking like the gears were slipping mine done it at highway speeds but mine shut down wouldn’t start back until about it set for 10 min
Yeah except mine never shut down
Yes minded exactly what you’re describing. After a long ordeal I had a new crankshaft position sensor installed and everything is working just fine.
Paul Miller yea replaced my crankshaft sensor also and it fixed mine also
My Jeep start to do that lost power on highway stay in the shoulder for 8 to 10 minutes then start like nothing happened.
Jesus G Lopez replace your crank sensor
I have the same issue
Hopefully it fixes the problem
Great video
Did you abs light ever come on because of that problem
No I never got a warning light at all actually
I have a truck with that engine and it Boggs down when I either change gears, or come to a stop but it’s only when cold
Mine did it all the time whether it was hot or cold, but it probably affects cars and trucks differently
@@matthew9826 did the crank sensor fix the issue
I am also having a check engine light intermittently
@@jakenoll8656 it did for me
@@jakenoll8656 if you have a check engine light I'd get that checked out. You could probably have something completely different like your mass, airflow sensor or something else
Changed mine out on my 2012, 2 weeks later did it again. Took it to mechanic, plug had a broke wire and also one wire was broke at steering column. $600 later…..
Is it the same for a 3.6 with a manual transmission?
Yes that's what I had
Easy Peezy! Thanks for the info, like the jeep color and the sporty hood design.
Hi i have an issue that looks like a same my Jeep while I driving slow and accelerate to 2 rpm it immediately stall
Sorry for the late reply Did you end up getting it fixed?
did you get a code for it im having acceleration hesitation and no codes
Nope I never got a code
