    P0033 - P012C - P069E Can't turn off MIL on turbo'd CTSV

    I've clicked the box, and changed to don't report and wrote complete, but these codes keep lighting on a 2009 CTSV that no longer has a supercharger, or the FPCM running the fuel pumps.

    Why do these codes not turn off now, and keep lighting the CEL on the dash?

    P069E is a special DTC and it cannot be disabled. Essentially, this code means the FPCM has requested illumination.

    Not sure about the other ones though...

    If the fpcm is still in the car it can be licensed and the codes disabled.
