P0013 and P0014

This forum has been a great help to me in the past and I am expecting great results this time. Thanks for reading.

2009 Cobalt LT, 2.2L, approx 160,000 miles

Wife came home and said the CEL was on. I put in the OBD2 bluetooth dongle and fired up my Torque app and it came up with a P0013 and P0014: "B" Camshaft Position - Timing Over-Advanced or System Performance (Bank 1)
P0013: "B" Camshaft Position Actuator Circuit (Bank 1)

Apparently, infrequent oil changes, or low oil or wrong oil can trigger these codes. I do regular 4,000 mile changes with Valvoline 5W30 Semi Synthetic High Mileage. Checked oil and it is good...actually still looks clean despite halfway through a change cycle. So, I am going to rule out oil being the problem.

The other more likely problem seems to be a bad part but I am unclear as to the name of it. I have seen Camshaft Postition Actuator or Variable Valve Timing Solenoid???
There is an intake and exhaust one and I believe it to be the Exhaust one.
Can someone clarify for me what part I would need to replace.

Also, I cleared the codes and my wife has driven the cars since with no return of the CEL to this point. It it returns and pops the same codes, I will replace the part necessary but I need to know exactly what the name of the part is and if possible a part number. AC-Delco or Dorman are both fine.
Thanks guys.

Your exhaust actuator is probably starting to stick, you will eventually need a new one. Easy to change, held in by one bolt.

P0013 Exhaust Camshaft Position (CMP) Actuator Solenoid Control Circuit ECM
P0014 Exhaust Camshaft Position (CMP) System Performance ECM

GM#12655421

You will find bought here: Intake points to the front exhaust to the firewall

Thanks Coby7. Wife came home today and her light was back on. I checked it and only P0013 this time. I suppose the P0014 is not far behind. I checked her mileage and she is right at her regular 4000 mile change interval so I am going to clear the codes and change the oil as it seems old oil can sometimes cause the codes. If they come back, I will be replacing the part referenced by your above. I will report back with a final outcome.

You may get lucky but once the sludge gets into the actuator it is hard to flush out. That's why GM recommends 5W-20 synthetic for 09-10.

Well, the CEL came back on and I checked it. It was just P0013 this time. I cleared it, changed the oil and filter and my wife just called me from the road. The CEL is back on. Not sure if it is just the P0013 again or both P0013 and P0014, but I am going to go ahead and spring for a new Genuine GM 12655421 Camshaft Position Actuator Solenoid Valve.

I will report back on the outcome once I get it replaced. I trust there is no real harm in driving the car until I can get the part and get it put in??? The car seems to drive fine as is.

You are correct, no harm will come to the engine if you keep driving it. And very little performance and fuel consumption difference!!!

Happened on a family member's '09 XFE around 100,000 miles. Sudden shuddering then the P0010 lit up (that's the intake actuator failure). The oil was changed at 3,000 to 4,000 mile intervals, so it can fail even with diligent maintenance.

Replacing camshaft position actuator solenoids is easier than changing a spark plug. Little more expensive but not a bad tradeoff IMO. One of the easiest CEL issues to fix. Even though the exhaust solenoid error didn't activate I replaced both at once, guess it was a good decision! There's a boatload of aftermarket ones on rock auto

P0014 solved

OK, changed oil with no luck in keeping the CEL and P0014 code away. I cleared the codes a couple times and within a day it would come back. I finally got my Genuine GM 12655421 Camshaft Position Actuator Solenoid Valve,

I cleared the code, installed the new CPASV and started it up. It was never running poorly before and was running good when I started it up, so I didn't know if it was fixed or not. I ran it around the circle (1/2 mile) and all was good. Then the wife takes it on an errand and 10 minutes after leaving I get a call. Oh crap, this can't be good. She says she stopped to throw out some trash at a gas station and while it was in park and idling was making some weird noises and idling really rough. I said bring it back home. Two hours later, she finally shows up. Said it stopped running rough right away and has been great since. Well that was a few days ago and about 200 miles ago and no more CEL and the car is running good. So I am going to call this one solved.
Thanks Coby7 and everyone else for the help.

It takes about 20 minutes or so for the ECM to rebuild it's data matrix and what your wife heard might have been coincidental with the ECM, once warmed up, going into closed loop with old data then it settled. Did you clear the code with a scanner or disconnected the battery?

Yah, that is what I told the wife. I said it was probably just the car's ECM adjusting to the new sensor.
I used an OBD2 dongle and the torque app to read and clear the codes.
