    Default P0101 - MAF out of range keeps setting - VE tune

    P0101 - Mass Air Flow out of range / performance keeps setting in my tune. Is it because I tweaked the VE table? Do I need to adjust the MAF? Thanks.

    Something is wrong with your MAF sensor and/or its wiring.

    I suspected that, the shifts are harsh too. However, the tune I am running seems to set the DTC more frequently, although I can see where indirectly it would irritate a slightly out of range MAF more with altered VE chart maybe? Well maybe time to upgrade, but I'd like to verify the sensor is bad?

    How different is your VE table from original...?

    If it's greatly different then possibly P0101 may get set...

    If your VE table does differ greatly, then see table C2911; otherwise MAF is dirty/faulty.
