anyone had these?? i paid to have the crank position sensor replaced but now im thinking i got screwed by the dealer and they never even did it..the problem gets better and worse when you mess around with the wiring harness leading to the CPS as well...wondering if anyone can shed some light on the issue seeing as they "cant find the problem" at the dealer

 

bump


come on guys!! not a single one of you can help me out here??

 

my crankshaft posistion sensor just went on mine..my car is currently in the shop...why do you say that and how long did they say it took them to do?

 

i gave them the part cuz i had bought one to do myself but the car happened to be in for an oil change and i figured hey just have them put the new one in...left the car there for a day...

im thinking it might be a wiring issue...the main engine wire harness runs right alongside the oil filter area and i pulled a little of that black wire loom **** off and the wires are drenched in oil....pretty bad design on GM's part if u ask me....so now im prob gonna pull all the looms off in the area and clean off the wires and see what i can find...

i cant even take it to anyone to have it fixed cuz im **** broke from spending $2500 to fix the timing chain and the associated damage that caused :-/

bumpin bumpin

 

i too had the crank position sensor circut malfunction deal i replaceed the sensor turned out that a wire from the CPS (crank position sensor) as it gets ready to enter the main wiring harness was cut some how.

 

thats what im thinking at this point...its such a bitch to get in there and work around the coolant and A/C piping

 

i had both of the codes and i replaced the sensor and ****... it wound up being the PCM went bad... both of the sensors were fine.... So you may want to check your PCM... also what issues are you having?

 

hesitating and sputtering over bumps, low engine power, much louder exhaust, difficulty managing the clutch so it stalls out a lot, no tach, guzzling gas and the CEL

 

same exact symptoms i had im tellin you bro check the wire

 

thats what im gonna do i just gotta get the miles of electrical tape crap off of everything

 

thats exactly the issue im having...

explain more slobalt

bumps is whats acting on me

 

checked the wiring all over the place including grounds and such...nothing looks outta place and the problem is still there...im really starting to bet they never replaced the sensor when they said they did....really pissed if thats the case

 

your sensor is more than likely fine... its a different issue... you prob have a wiring issue or a bent pin or something along that route... I have had the same issues and thats the difference with two different sensors, replaced the PCM and i have been fine.

also, im waiting for SLOBALT to chime in to see if he can shed more light on the topic of his fix

 

i just took the whole harness out, and checked every wire...everything appeared fine and had continuity. (i did tho had the car running, then wiggled the wiring at the harness and I could make the car start to die or die completely)
so i ran a both new wires from the sensor to the PCM and starting it up, running amazing.
giggled a little and i got a p0122 (check the tb connection, plugged it back in after unplugging it. restarted it pulled it out the garage, fine. turned it off, did some things, turned it back on and it stalled on me.

codes that appeared
P0122
p0335
p0336.

now i cant get the car started. Im so confused.

 

''''

 

cars back at the shop since thurs...waiting to hear from them...i dont have the time or patience to deal with this aggravation anymore and i honestly wish i had the money for a new car

 

i had to buy a new engine harness

 

took the car back from the shop...guy said he "couldnt find the sensor" on the car...pretty much lost confidence in him right there...got a new crank sensor and wire harness...gonna install those and see what happens...

2 questions...

when i took the old crank sensor out it was coated in oil...is that normal and/or ok??

will the check engine light go off on its own if the problem is resolved or do i have to reset it myself??

 

it will be covered in oil as it is exposed in the crankcase, the MIL will need to be reset... I just replaced my whole engine harness today and am pretty certain it is fixed!!!

 

the code is only half (if that) of gettign to the bottom of the issue;

if your car is still under warranty (I'm guessing not if you're buying parts) you should be able to get the dealer to diagnose the problem @ no charge;

I would be inclined to think that the issue isn't with the CPS itself, because they are a simple maget design;
if it works, it works - if it doesn't work the car will not start.

a wiring issue makes more sense.

ok, going off memory I believe you stated you removed some of hte loom cover, and got oil on the wires, and were wondering if that was a problem;
it shouldn't be.
the loom is there for two reasons;
1) to keep wires together & (theoretically) out of the way of anything
2) to keep the wires contaminant free, so that should a repair need to be done, the technician doesn't have to spend time cleaning the wires.

as stated earlier, the CPS is exposed to the crank case - it is normal to have oil on it.

if you do not have confidence in your abilities, and changing the CPS doesn't fix it, you should consider dropping hte car off at your preferred shop to get it diagnosed properly;

FYI: the GM service manual will have a whole check list to diagnose a given problem when any code comes up...

I hope this helps clear this up & is of some help ~ good luck!

 

... start your car, wiggle wires and see what area of the harness makes the car start to die or shut off completely.

 

im pretty much stuck doing this myself as ive had both a GM service dept and a local shop both try and resolve this issue to no avail...im just going to start replacing parts/wiring from the CPS to the PCM and see what happens...im gonna see if i can get my hands on a service manual and see if theres anything there i havent thought of yet thanks

have u seen how many wires are in that area!?!? lol im gonna do the CPS and the short harness that connects it to the main harness today and see if that does the trick..*crosses fingers*

 

obtw... get rid o that quick disconnect... just hard wire it in... thats issue number 1 forsure

 

funny thing is my moms 2008 G6 with the 2.4 Ecotec has it hardwired in...no quick disconnect

 

that solved it...FINALLY!!!
