The Check Engine Light With Code: P0011, P0014, P0021, P0024, P0341, P0346, P0336, and/or P0391 on GMC Acadia

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.

P0011, P0014, P0021, P0024 codes Traction control is off.. engine light is on. Weekly issues with this vehicle.
Car started running poorly and finally will not run at all. The car will still start but has two reported error codes P0011, P0014, both related to cam shaft sensors.
