    Corvette C6 P012B DTC Help

    Hi!
    Really need help, can't solve my problem. In the process of tune the error P012B appeared and it is not removed. The error appears immediately when the ignition is turned on, when the engine is not even running yet, which is very strange. I can not understand what is the cause. Tried another sensor, the problem is not solved. Tried to make a new wiring from ECM to the sensor, the problem still does not solve. Even disabling DTCs in the settings does not help. I will be very grateful for any hints and help.

    Try putting all the supercharger Torque management back to stock. You can leave a higher boost limit but the rest.. go back to stock.

    I made a file like this, but it didn't help. The error is still hanging in the memory.

    Since that is a permanent code, it may have to see some drive cycles to clear? At least enough that it has a chance to rerun the test.

    Is the DTC pending, current, history or permanent? If it's only flagged as permanent, it will take several key cycles to clear. You can't clear permanent codes with your scanner. It will be there until the PCM decides it can be cleared.

    Screen shot shows as "permanent" (only).

    Ah its permanent..

    Just disregard. It means at one point it set this code. It will likely go away on its own but after lots of drive cycles.
