    MAF sensor reading way low temps?

    I have a 2002 c5 with a Gen3 MAF sensor, Gen4 MAP sensor with a LS2 throttle body and LS3 engine with all Racetronix wiring harnesses for the conversion.
    Anyhow I see on the HP Scan my MAF Intake air temps reading -38F and not moving, key on eng off and running.

    Is there a MAF test or a change I can do to rectify this? THX !!!Intake Air Temp LOW engine running no changes.hpl

    I attached the scan file below.............

    That's an open circuit reading. Broken wire, bad pin in the connector, etc.
