I love my carbureted 86 Mazda, no computerized bs to go wrong. EMP proof too other than the battery.
not emp proof
Magnets are weak on cheap ones, and when you do this clean your connections with electrical cleaner wd40 brand is good, do this with the battery disconnected and give a good 5 minutes and shake it to get any excess out, i hosed mine out pretty good, it dries fast but this is just being safe before you put power back thru. If your having problems not starting afterwards, unhook both your battery cables and touch them together but do not let them touch anything, wrap them with tape if you want, it'll drain residual energy from the electronics and drain capacitors. Let sit few hours or even over night. Also had an issue connectors clicked but didn't Click with a clean sound had grease and grime not letting the lock really set. Can use a multimeter and check your wires, 12v power and around 5-10 on signal wire, middle should be neutral, 3 wires. Should be pretty standard for most cars
Thank you for the video. I just replaced a crankshaft sensor and now car won't crank.
Same here. Did you find a solution? 1999 toyota corolla.
Me to 12 chevy sonic
Me Kia Sorento 2010
Did figure it out
I have a 2007 Chevy equinox and they made this vehicle from 05 to 09 I think. I’ve change the crank sensor and had problems cause wouldn’t start ruff idle and cut off. The point I’m getting at when you change the crank sensor replace it with the exact part manufacturer that came out from the vehicle not all manufacturer wire there crank sensor the same.
Did you ever fix your car?
@@JCGible yes I did fix it, the crank sensor on my vehicle is 3 pin connector and different manufacturer wire them differently, I use rockauto to find the original part
@bobgnops Ok, Thanks glad you got that fixed
I have a replaced the Crankshaft Angle Sensor three times and each time the small magnet approx 1/4 had detached from its glued position with no other physical damage to body of the sensor, each time the magnet was retrievable. The sensors were purchased from the dealer and from Advance Auto Parts, the results were the same lasting one or two years. The installation in very time consuming due to the sensor mounted location to engine behind the timing belt. The vehicle is a Kia Optima 2.4l.
I just replaced the crankshaft position sensor on my 99 Dodge Ram & it’s still having the same issues! I’m so mad cuz that crankshaft sensor was a Bitch!
Hopefully it just needs to relearn or I may need to do camshaft sensor too 🤷♀️
Whatever happened withthis? Did. You have To rePlace the cam too?
3:50 I have a 2005 yukon with 5.3. I changed the crankshaft positioning sensor and it will not start . Any suggestions.
Did you figure it out?
2018 Kia optima, just replace the two sensors and a week later it didn’t start at first, I️ was told to check my alternator any ideas ? Thank you for this video!!!
You changed cam say have sensors? If so, is the sensors
I have a 06 Nissan frontier and check engine light indicated cam pos sensor needed changing. Changed all 3of sensors, 2 cam and 1 crank sensor. Unplugging the cam sensor was frustrating and irritating cause we couldn't get it off but finally did. Once all Nissan OEM sensors were installed engine light went off. But now truck takes a long time to crank before it starts
Hi just wondered if you managed to sort this at all? I'm having exact same problem replaced faulty cam sensor after fault code showed and now it's a real struggle to start but no codes showing
I just changed mine on a 2012 Nissan Pathfinder, but now I wonder... will the check engine light go off on its own after driving it?
Yes one of the sensors was defective so had to change it again. Took it to AutoZone and said it was passenger side
To fix long crank problem, you must use manufacturer OEM sensors.
I changed my camshaft sensor and now it has a hard start but runs better than before
This is very good advice. You can't beat experience. I give it two snaps up !
I got a 2014 in put all new Crank sensors in our new pack change. The valve covers is everything running is running good but sometimes when I crank I get a good hesitation what did you do it run run great faster than before.
I tuned up my 2014 Nissan Maxima sv put everything camshaft sensors 4 new one from AutoZone in has a hesitation, crank sometimes what you think it is
@@rodneymccracken8823get OEM. Hitachi
Mechanic just replaced the crankshaft position sensor now I am get low pressure oil warning on and off with CEL. A little worried. Taking it in tomorrow via tow.
Replaced engine, twice, still getting p0365 and p0369. Wiring is good all is good. 2012 ford expedition 5.4L also replaced crank sensor and cam sensor bank 1. Still have the oe ford sensor for bank 2. Swapped bank 2 and bank 1 sensors and still getting same code
Check bank2 wiring/harness?
lol you replaced the engine twice?? Man ppl need to check wtf they wrote cuz auto correct or stupidity is blocking the details here
. If I insert the camshaft crank sensor, but do not connect the wire connector, then it still runs fine. If I pull out the crankshaft sensor all together, then the car won't start
My car runs fine for about 3 days, then the ECL comes on, but then i remove the Camshaft sensor, clean it, rotate the barrel part of it a bit as it seems really stiff, then it runs fine again for 3 days with no ECL
very confusing
Replaced mine. The car runs but sometimes dies while idling at the traffic lights. No idea what to do.
What if the wiring too the crankshaft postion sensor is loose will it cause stalling sometimes ? and engine misfire ?
Had a shop replace my crank shaft position sensor on my 2014 Hyundai v turbo and now it seems to either be in limp mode or something g like that surges at around 2500 rpm’s and the code came back for a crank sensor
Same here but did it my self started it first time was fine but still in limp mode an cam sensor cade back on my 03 jetta
Did you ever get your situation figured out? I'm getting a cold p0335 on my 2012 Genesis saying it's the crankshaft position sensor.
I have a 96 Toyota Camry 2.2 4 cylinder and the clip on the connector is broken any tip on how to keep it together. I can’t find a new connector the car is old
Does it matter if you switch 3.4 motor from 2003 Impala to 2004 Monte Carlo? New cam sensor installed and now have the crank no start problem.
I just had my crankshaft and camshaft replace but my engine light is still on along with my traction light . My car runs good but now is have trouble starting at times . I have a 2011 Toyota cam well my engine light ever go away? Do you have any advise for me?
If you have multiple dash lights it could be the speed sensor is bad
Mi audi no trabajan los cambios de velocidades .cees que sea el crankshaft
So if I buy one from auto zone is that considered cheap or bad idea??
Bad they might work a few days. I'm going through this now
You should do all the diag work before you replace parts, not after.
I have Camry 08 I change the head gasket then, everything is correctly, the starter is turning but coils not firing
I have 2014 ram1500 2wd replaced the brake module and all four sensors but the traction control light is still on
Can you help me
Wheel speed sensor clean them
How do you do a manly recess on a 2011 Cadillac SRX 4 performance
I have a 2015 nissan altima getting p0335 changed crankshaft sensor and pigtail for sensor still getting check engine light with code car runs fine other that engine light showing any ideas
I changed my crank on my 5.3 not my engine won’t start so I gotta relearn if so is hopefully that’s my problem I put my whole engine together hoping it would work but no
A youtube video just had a guy that bought a "vident iLink 400" brand new on ebay for $156 and used it to do the crankshaft relearn procedure on his chevy 5.3L and it fixed his problem.
I replaced both and the codes are still there and car won't even start. I have a chevy cavalier.
I replaced both too and my car runs poorly now and won’t shift correctly. ‘98 Cavalier 2.4L. I’ll let you know if I find anything out, going to take it to a mechanic likely
@haydenolsen4241 did you get it fixed
New cam position sensor. Getting 12v in one pin but no 5v reference in other pin. Ground is good and fuses are good. Where should I start?
Check ECU
I changed both camshaft sensors at same time but when start my car it's running really rough and sounds like it's not getting any oil. I have a 2014 hyundai elantra, any advice for me?
Hyundai - trade it in for another car
@@buzzlight2nd1 can't really trade in something you can't drove. But it's been figured out thank you, I just had to do a little research myself. It was a matter of changing the oil control valve.
@kathytaylor5680 so after the oil control valve was changed... you no longer had the issue? Hyundai Santa fe I'm working on btw
I just had my camshaft and crankshaft replace and my engine light is still on along with my traction light . My car starts but takes longer to start. Do you have any advice?
@@zacharybennett1450 same here
Ok so I just replaced my crankshaft position sensor and now the thing is getting triggered for some reason. Any advice to what is triggering it would be helpful. 06 Kia sorento stick shift
Need to buy the crankshaft sensors from the dealer Kia
my car is dual cam I was getting a P0340 so I replaced both sensors code cleared but now engine wont start ones a cheapo sensor and the other is an OEM replacement, if I unplug the cheapo sensor the car starts up and runs in limp mode should I take the chance and replace the cheapo sensor with matching brand? should I replace the crank sensor from the same brand too?
Always use Oem on ignition parts
The magnets are weak in cheap ones
Where is a cam sencer on a 2000 Chevy 2200 4 cyclinder motor
I have a 2014 ford fusion and I've changed out the camshaft, crankshaft censors, plus I changed spark plugs, my coils where fine its getting gas to the fuel line I also changed the vaccum pump for brakes and its cranking but not fully turning over to catch fire to crank can someone give advice for this issue
Please help looking for information replace Cam all lifters with a licensed mechanic. My truck went in with a bit of a tick from one of the lifters. I got it back and it sounds like a diesel. He can't explain it he says his work is quality don't know what to do please help
Sometimes the engine needs to be driven a bit before the valve train noise goes away. They could have also been installed wrong or the wrong-sized lifters installed. I would let the engine run a bit and see if it clears, if not the mechanic should fix it.
2008 Chevy Colorado 4door 4x4 3.7 5 cylinder automatic transmission 1 cam shaft sensor 2008 new motor 2010 has 2 cam shaft sensor only has one hook up
Cant drive. Replaced both sensors. Still stuck in limp mode. Stupid car
sometimes disconnecting the battery overnight resets the computer
I changed the crankshaft position sensor and my truck runs it turns on but all the sudden shuts off sometimes it runs for 5 minutes sometimes for half an hour with no hesitation just shuts off what can that do
@@josediazdiaz1913Spark Plugs and coils. Coil cables might be bad. Or also dirty fuel injectors. Even not enough oil or bad oil.
@@josediazdiaz1913You may have a bad wire in your CKP(Crankshaft Position Sensor) and the either the power, ground or signal circuit is NOT reaching the sensor. You may want to carefully examine your wires for cracking and/or damage. I recommend you watch this video by Top 5 Auto Repairs, titled CAMSHAFT POSITION SENSOR GOOD OR BAD, ruclips.net/video/NxmvTjTqDVQ/видео.htmlsi=4kNOawfNY--aX-di
Does it just stop or does it splutter to a stop, did you fix this?@@josediazdiaz1913
I changed my cam and crank sensors on my 2008 corvette, but the only thing that happened my tachometer is not working any more, you thing that is my crank sensor or my cam sensor,, Thx ..`
Thanks!
2011 Sentra. My mechanic changed both, told me if that doesn't work its the timing belt, which is going to cost a fortune. Got the car back - it's worse than before. I don't really know this guy to know if he's telling me the truth.
I’m in the same boat. Changed the cam shaft sensor, timing belt, spark plugs and still won’t turn on.
@@SuckmyballsBish damn that sucks. I paid a lot to replace the timing chain, but at least it runs now. Hope it works out for you.
Timing belts are either good or theyre broke, nothing in between. Get a new mechanic..
So a mechanic that was working on something else on my car accidentally broke the camshaft cap on my 03 Corolla. He replaced the cap, but a lot of people told me this is not right & that he owes me a new head! Is this right? The day after my car didn’t want to start & I had to get towed! After I got towed it started right up. I don’t know what he did..
Camshaft cap? New head? That seems a little extreme
my mazda is throwing the P0340 code. not only that the Tacho is eratic. it goes up higher than the actual RPM then just randomly drops to 0 rpm. car runs rough. i replaced the cam postion sensor and it made no difference at all. if i clear the code it just comes back again after about 30 seconds of the engine running. any advice ?
I'm having the same problem. Have you got any answers yet
Got the same issues too for my mazda bt50.
if you go to my page i have made a video on how to fix it

I have a 2001 GMC Sonoma just replaced the crank shaft sensor it starts and idles but as soon as it reaches 3000 RPM it just dies any ideas
You have to do the relearn procedure. A youtube video showed a guy use a brand new "vident iLink 400" for $156 from ebay and it fixed his 5.3L GM
Can I buy a new crank shaft sensor and kam sensor and just put them back in with out reprogramming them Jeep Cherokee 2007 model thanks
Not with the jeep my friend..needs to be. programmed in.thats how they have programmedcthere ecu.
Unless you take the fuse under the hood so its not detected while disconnecting it and reinstalling a new one...fucking stupid system..thats how they make there money....theres some good people out there..that can help you out..
Good.luck
Did it work
engine cranks but wont start. Tachometer does not move while cranking. 2010 Nissan Titan
Why would the tachometer move while cranking? If the engine isn’t starting the tach shouldn’t be showing any rpm’s 😳
Hello ,, I need some help here,, I install a 5.3 ls 111 on a 2008 Corvette ls3 engine, but I used all the covers from my ls3 engine, this 5.3 has the cam sensor on top in the back of block but I just used a plug on the hole,,, and used my front original sensor , even put all sensors new, but now it wont star,, can u send me some info on this one,, thx

I have a 2014 Chevy traverse and I replaced my cam sensor about a month ago and now I'm getting p0016 error code on my odb2 and my car doesn't want to turn over but eventually it starts. I've got a new crankshaft position sensor getting put in this weekend by my friend and I sent him your video and he works on cars all the time, I'm not getting the error code for the crankshaft position 1 center, I'm getting a code saying that cam shaft position 1 sensor and crankshaft position One sensors are not communicating properly. What do you think it is?
I’m no expert whatsoever but it sounds like you also need to replace the crankshaft sensor like you mentioned cuz your new cam sensor isn’t communicating well with it like this video explains

Is it possible the engine has only 1 cam position sensor? 09 camry 4 banger. Also its a 2 wire, not a 3 wire.
Yes, some vehicles have only 1 Cam sensor, and the older sensors can have 2 wires.
@@HVAC_Mechanic 1 last question. Should there be voltage there not running with the ignition on? 5 volts i think?
Just replaced Cam sensor in my 96 bmw 328i and when reconnected the wires i must have disconnected my air injection sensor but i dont have any idea where the wire is at and there is no crank now.
I replaced the camshaft positioning sensor but not the crankshaft i was going to change that one too would you recommend that? Wires look good but i was told it could be a dirty fuel filter ?
I would follow the codes that were given. A Cam sensor or Crank sensor code is different from a clogged fuel filter code. If you have multiple codes, there may be multiple issues.
@@HVAC_Mechanic the crankshaft position doesn’t always throw a code.. there’s not always a code thrown for a variety of issues but I wish there was
I replaced my sensor, sometime if you shake your battery it'll start up ahaha.
Shake your battery? Lmfao hopefully you meant disconnect your battery not shake it 😂
@lh98 lmao I was even joking, but I learned at one point it has an aftermarket positive terminal that wasn't even tight all the way.
Bro why are you deleting my reply
Im just trying to help out a guy who has a paticular problem
I haven't deleted any reply
@HVAC_Mechanic that's strange. Sorry to accuse , maybe a glitch in the matrix

Did you get factory sensor from dealer ? did you find problem ?
I’ve changed my camshaft sensor A, bank 2 on my Kia Sorrento.
My Kia came up with engine light and speech (on screen) to get to mechanic “Soon” initially.
So many details from each move but my Kia always ran and started, well, I might add.
Changed sensor, engine light came back, same code P0346.
Purchased OE Kia part.
Now Kia’s speech (on screen) says get to mechanic “When you can”.
I’m going to change fuse again. This was the first thing I did.
If I come up with answers or possibly solutions, I’ll share.
do the crankshaft relearn procedure. A guy just did it on youtube with a "vident iLink 400" that he bought new on ebay for $156 with his 5.3L chevy
