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
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
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!
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?
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
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!!
SAVED me a fortune..... three dealerships failed to diagnose....... THANK YOU!!!!
No problem glad I could help.
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!
Thank you you saved me time and money right before a roadtrip so much appreciated
Awesome glad to help!
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
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!
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
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.
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!

Easy Peezy! Thanks for the info, like the jeep color and the sporty hood design.
Bro, switched out crank position sensor, worked like a charm , right away. Thanks for the info...
Awesome!! glad to help
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!
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!!!
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!
I just replaced my camshaft sensor, didn't help. I think you just helped me. I'll replace the part tomorrow. Thanks
Same!
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.
Your video helped me fix my problem very informative thanks I would have never figured it out on my own 👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼
Awesome!!! glad to help
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
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 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!
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
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, 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...
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 😪
Also wanted to add, this fix improved my mpg by 5... wow!
That's awesome!
Excellent very educative and informative Thanks.
Thanks for the video it’s worth just replacing to see if that fixes it.
Awesome! Such an easy fix. Sweet! 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.
Thanks for making this. Going to change mine today.
Thank you for making this video!
Issue fixed!
And what an easy install!
Part #PC893 made by Standard - Crankshaft Angle Sensor
Takes a 10mm wrench
Awesome glad to hear it fixed your problem!
Just replaced mine!! Fingers crossed 🤞🏻 thank you for this video!!
It worked, right ?
@@wulfclaw4921 yeah so far so good and I’ve been on two road trips
I have the same issue
Hopefully it fixes the problem
Great video
Good info man thanks. I have a 2015 and if it happens to me , I'll know what to do.
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 saved your video in favorites in case something like this happens to me. Good video. Thanks for sharing.
Same lol anything to avoid a mechanic that will probably fix the wrong thing
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.
Thank you been trying to figure it out shop's couldn't figure it out and it didn't want to do it when I went to go show them also started off small now doing it 2+ times a day
Yeah it's very annoying, especially when they charge you money and don't find the problem lol.
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
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.
Good to know. Thanks for the video!
Thanks for the insight. I'll keep this information filed....
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?🤔
@@thereddragonslair9548 Yes, no issues at all...Delphi SS11407 Crankshaft Sensor
@@usnchief1339 thank you so much!
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.
Another jeep saved! Thank you bro it worked for me 🙏
Awesome!!! happy to help
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!!!!!!!
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
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.
I have the same problem. Thanks for the video!
No problem I hope it helps fix your issue.
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.
Respect bro, totally worked on my 2013 sport😁
Awesome! thanks for letting me know this helped you.
I actually thought it was something serious..crazy
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
You my man have saved me a lot of money haha thank you!!!!!
No problem I hope this solves your issue.
@@matthew9826 it sure did!
@@nancyveneausmith Glad to hear! Thanks for letting me know.
I had the same problem... Fix my issue last summer
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.
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.
Great video, bud! A couple of things: 1.) That hood looks amazing! 2.) Is that a bit of a valve cover gasket issue down there or is it early and my eyes are playing tricks on me? Anyway, thanks for posting!
Thanks! It's apparently a common problem with these 3.6s I currently have a gladiator with the same engine and I had to warranty it out for the exact same reason. It's the gasket for the timing chain cover. Luckily it started leaking before my warranty was up. I bought it brand new in 2021 and it started leaking around 2023. My JK started leaking right after the warranty of course lol.
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
you are the man
Thank you! Good to know.
Thank you for the info 🙌🏻🙌🏻🙌🏻🙌🏻
Glad to help
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 got a 2012 had the same issue but my did through a intermittent crankshaft sensor code strange how it didn’t for u
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.
Blessings king 👍🏾👏🏽👏🏽👏🏽
All I can say is thank you! It fixed my problem.
Awesome glad to hear!
THANK YOU!!!
Thanks so much!
How long to change Trany oil on my 2015 jeep rubicon with synthetic tranny oil I have 67,000 miles?
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
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.
I hope this is the issue I just began having. I was thinking it had something to do with the heat but I never had any issues with overheating before. I was on the freeway and when I tried to go around slower traffic and gave it the gas it was like somebody tossed out an anchor and I thought I was going to lose all power so I pulled over. Not knowing what had happened I checked under the hood and everything seemed fine. No Check Engine Light so no code to look up. Got back on the road and it seemed to just not have any guts, babied it a little bit and it eventually came back to normal. Happened twice so far so I'm going to replace this sensor and see what happens. Thanks for the video.
Did it solve your problem? I've been having the same issue. Feels like the ABS/VSC system kicks in or the engine shuts off or something when I go to accelerate. It's pretty bad bc I do alot of highway driving. Mine is a '14 on 35s with 78k. Thanks.
@@marcsciarrotta3109 It did cure the issue at that time but it's back again. I just bought another CPS and will be replacing it this weekend. If it does, I think I'll buy another to keep in the glove box. BTW mine is a 2015 JKU Rubicon on 37's and 55k miles.
@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.
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.
I'm try it. Because I'm thinking fuel pump engine but jeep cranks right up. Just when I'm driving 🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼
Had the same problem on my '80 wrangler. It fixed the problem plus gave me 50+ HP
Your jeep is beautiful. What size tires/lift you running???
Thank you I was running 34-in tires with a 4-in teraflex lift.
I had the same problem. Cause was driving over too much water
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
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.
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.
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…..
Subbed 👍👍👍👍👍👍👍👍👍
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.
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.
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.
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! 🤙
Did anyone that fixed this issue with a new CPS have the dealer give them error codes PO171 and PO174? The symptoms sound very similar to what's going on with my daughter's 2014 wrangler, driving along and all of the sudden engine starts to shut down and acceleration is almost impossible. Additional symptom is slower than normal acceleration from a stop once jeep is up and running again. Unfortunately, dealer couldn't replicate the issue, yet it has happened again. Thank you in advance.
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.
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'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.
I replaced the crankshaft sensor and it fixed it. I had no codes showing up.
Awesome!!!
I hope this works
Interesting!!
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.
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.
