Verified

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.

    check engine light came on three times since 48000 miles, since I purchased this car,replaced sensor to gas tank for pressure, still came on, repaired wire to sensor, still came on, this time it said fuel leak, no fuel leak! they reset the light, a week later it came on again, it just so came on the same day I got a notice from On Star that my OnStar was not on. I chose not to use Onstar! Something Fishy here, Can Onstar make this check engine light come on When they want to. I give up! the engine check light is still on and the car runs fine.
