Verified for the Cadillac CTS

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.
