I recently replaced the cam position sensor on my 08 Sierra. After my 6l80e swap i needed a 2010 ecm to make everything run which was when i got the code. I have researched before i bought the new cam sensor that the 08 and the 2010 5.3s have the same sensors. They are identical. Now that i had eliminated the fact that they may have different cam sensors i replaced it. The old one was in fact cracked (possibly from me swapping wire harnesses im sure) and i had a hell of a time removing it. Now that i replaced it i am still getting the p0010 code, cam position sensor open circuit is what the handheld reader describes. One dealer i went n asked for cam sensor relearn and they did it they say. Took bout 15-20 mins and only charged $35. Im like 3 mins away from that dealer and after i got home and turn off I restarted and killed it and then checked codes and i got the code again. The idle is way better, still rough but not as bad and smooths out in about 30 seconds on cold start an dis fine once warmed up and imm getting better gas mileage than with old one. It seems to be all around better but still getting the code. I went to another dealer to see if the first may have done something wrong and their shop manager says theres no cam relearn that can be done. WTF? So he then says all there is is a crank relearn but since i didnt change that sensor a relearn isnt required since the ecm relearns cam sensors on its own. I was like well why am i getting the code still? He says if you give me some time with ur truck i can figure that out. Ummm no thank you i dont want to spend $100/hr which is their charge. He thinks the 2010 5.3s have a different sensor than an 08 but like i said i already cross referenced both and i get same part numbers. One mechanic friend says their maybe more than one cam sensor on a 2010 5.3 but i cannot find a 2nd sensor anywhere i have looked.

Any bodyknows whats the real answer? is there a cam sensor relearn or not? Any ideas may help. i also read that p0010 could also mean:
Faulty oil control valve (OCV); Open or short in the VVT/VCT circuit Open or short in the OCV / solenoid valve; or lastly Damaged computer (PCM)

Like i say any help is appreciated.

 

 

Morning bump

 

I thought the crank relearn was when the crank and cam timed them self together.
I had a good friend ( he is up to date on a lot of LS stuff) tell me that you can clear the codes and drive at 55MPH for XX amount of miles and then slow down slowly to 35 then slowly easy up to 55 and it will crank relearn. I'm not sure if that would help you or not or if it even works..

 

That code is for a wiring open or short circuit between the pcm and the cam phaser or faulty cam position actuator. That's the 2 wire connector on the front of the timing cover dead square in the middle.

It's not a problem related to needing to re run a CKP relearn procedure. It's either a hard failure or a mis pinned wire during the pcm swap.

The only real way to figure it out is a tech 2 or equivalent scanner and a trouble tree for the code and follow it out.

 

I tried the 55mph and 45 mph and slowing down procedure but i think that only works on NBS .. It didnt work for me anyways after several attempts ...

I was afraid it.was gunna be the wiring harness itself or the 2010 ECM because the cam sensors are identical in both 08 and 10 ... THE ecm was a used one and the wire harness was new from GM parts direct.... Im gunna check wires for continuity ... One side of O2s isnt reading either and i have swapped them around and same side says no signal but that sensor works on opposite side no issues.. SOOOOOOO its either bad harness or ECM ... Going to try continuity test soon as i get time ... 6 nights a week every week and leaves me not feeling like doing much on sundays lol bad back dont like to be on the ground so im gunna need my helper lol hard to get up early when on straight night either ... Will update when i get the testing done ... If faulty then im gunna try my luck with another harness hoping lightning wont strike twice on a second one eh .. If passes then im get new ecm .... Thanks for input guys

Edit: re-read ur post 01WS6 ... Will try see if i repin that 2wire connector solves my prob it may be opposite of 08 for 10 ... But i did find pinouts for the ecms of both yearsand they were identicle ... But may need that 2 wire pigtail reversed ... Will see soon as i can get into it ... Maybe sunday i will see

 

do you have DoD / AFM? or did you delete it

 

If you are having 02S problems as well I'm placing money on DOA pcm.
The VVT actuator connector pinouts are the same from 08 to 10 connector is not your problem.

 

Have DOD and is off in the tune ... It will be deleted eventually

 

Yea ive dug into the pinouts and had help from 2 very helpful guys on here that sent me the pinouts and they are exactly the same... I was just wondering if that 2prong sensor may be reversed though for 2010 ... And my understanding from GM is that VVT in 2010 is same as DOD in 2008 seams they changed the name of it cause so many people hated the DOD because of oil consumption issues(was a gm techs opinion onnthat lol)... Same timing same programming and my tuner said my 08 programming looked same as the 2010 one when he got my data logs ... except formthe sensors not functioning lol ... So thats why the pin outs are same from what i gathered over last cple months ... So yea from what your advising and what i read if the pins arent swapped on that sensor u spoke of then im leaning on getting a new pcm for it.. The used one got me out of a jam i was in because i had sold my third vehicle prior to my 08 breaking down so it was worth the money i saved buying used pcm at the time .. Time to spend couple extra now ...
