That sounds like a Mass Air Flow sensor. Why are you checking it? What are your symptoms? Make sure your air filter is clean.

The wires going into the MAF are as follows:

White/Red = Ignition voltage

Blue/Black = E2

Black/White = E2G

Yellow/Green = THA (This is the IAT signal to the PCM)

Gray = VG

Hello! The Intake Air Temperature (IAT) sensor has the following wire colors...Gray/Red and Gray...
