SOURCE: 2002 chev avalanche mat sensor

I assume you are looking for the wiring for the IAT because MAT sensors are no longer used..

here you go

black / white - PCM ground
pink - fused 12-volts
yellow - MAF signal
tan - IAT sensor signal
black - IAT sensor ground

manifold temp. sensors are no loner used.

I believe you are looking for the IAT "intake air temp sensor" which is part of the mass air flow sensor.

good luck

    Take a tape measure and measure acroos the middle of the rotor, but it should tell you on the rotor what size it is. if push comes to shove take one to the parts store and match it up.
