Easy one, tell me what the DTC: "MAT Low" Means?
I got a DTC while logging, and I was wondering what MAT Low meant, it's error Err23 on my 93 Z28.
BTW I used Datamaster to log...
Thanks.

DTC 23 = Intake Air Temperature (IAT) sensor circuit (signal voltage high, low temperature indicated)
The older code lists referenced the "manifold air temperature".... but MAT = IAT.
Low temp - high resistance... could the plug be disconnected?
