Vehicles with certain V6 engines may illuminate the Check Engine Light one or more of the following codes: P0011, P0014, P0021, P0024, P0341, P0346, P0336, or P0391. Our technicians tell us that some vehicles may require a powertrain control module (PCM) software update to correct this issue. Other vehicles may have excess camshaft end play on one or both cylinder heads which will need to be corrected using special procedures outlined by GM.

The dealer says I need a new timing chain the code on the invoice from the dealer is p0011
Engine idles rough, RPM fluctuating below 1,000 RPM while sitting idle, and check engine light is on. Diagnostic ran and recieved codes for multiple misfires and misfire in cylinder's 3 & 5. Removed and replaced all 6 spark plugs and 3 & 5 cylinder ignition coils. Original gripe continued, ran another diagnostic recieved codes P0014- Exhaust Camshaft Performance Bank 1, P0024- Exhaust Camshaft Performance Bank 2, P0122- TPS Sensor 1 Circuit Low Voltage, P0123- TPS Sensor 2 Circuit High Voltage, and P0100- Mass Air Flow Sensor. Still waiting on resolution.
I have the same code, along with codes P2135 & P1516
Check engine light came on, dealer checked code and replaced cam salenoids (sp?). Light went off for one day then came back on. Now the dealer is saying it is the cam shaft and dual timing chain.
Hit a bump, the vehicle engine started run fast with trans pulling. I looked that the gear shifter to see if I had put the vehicle into neutral by mistake, it wasn't. The vehicle went back into drive and begin to pull. The check engine light came on and the transmission would not change out of low gear. Stop at an nearby AutoZone and had it checked out. The clerk check into it and the code was for a TCM problem. I took it to a transmission shop where they cleared the code out and that problem stopped. The transmission began to shift and the check engine light was also out but the traction control light came on and vehicle began to run rough. Out come to follow. It's still in the transmission and it is a full service shop. Thank God. Was to leave for PA next month. To see new granddaughter.
