Hello all, it's been a while.
I have a 2004 V6 with 162k miles on it and about week and half ago CEL and VSC lights came on. I noticed a slight rough idle. Plug in my OBD II scanner and it was reading P0016 Camshaft Position A - Camshaft Position Correlation (Bank 1). Based on some reading on here I was thinking it was a stretched timing chain so I didn't drive it until I could get it into the shop.
Just had in the shop (local independent shop I trust) and they did a diagnostic and said the following "Check Engine, found P0016 - Crank/Cam Position Correlation B1 S "A". Check circuit, bank 1 VVT solenoid will not command from PCM, VVT solenoid checks good, not getting signal from PCM".
I talked to mechanic and he thinks its something electrical related and recommended have dealership take a look at it
.
Since Thursday, I cleared the code. Friday CEL and VSC lights came back on. Ran the scanner and got P0010, P0012, P0074 (no more P0016).
P0010: “A” Camshaft Position Actuator Circuit Bank 1
P0012 - Camshaft Position 'A' Timing Over-Retarded Bank 1
P0174 - Fuel Trim System Lean → Bank 2
I cleared all these codes. And today P0012 came back but no other codes. Cleared codes again and CEL/WSC came back on again and read P0012. Truck seems to running fine otherwise.
I’ve read a lot of the other post on here regarding P0012 and the other codes. I plan to get the oil changed this week however I have been getting regular oil changes every 5k. I know some people say to change out the OCV. I may try that as well if oil change doesn't fix it.
I also took off the cover on the front of the engine to take a look at the time chain tensioner. I am unsure of what to make of the picture as I do not know what it is supposed to look like.
Any advise on how to troubleshoot or different things to try? I can take it to the dealership but I know how that goes and would prefer to figure it out on my own if possible.
Thanks in advance,
