IAT sensor has been a pain
Fresh motor with turbo tuned s300
OBD2B GSR harness into ITR motor
New IAT, check voltage and there's about 5v on signal wire, and ground is good. If there is power and good ground on it then leads me to believe there is good connection on the harness. I unplugged the battery overnight and still CEL came on for IAT. IACV is on too but that's not a problem. I tried all 3 plugs that are the same, maybe I got them mixed up, but CEL didn't go away.

Re: IAT sensor has been a pain
What is IAT reading in smanager? If youve got 5v reference and good ground, then either the signal wire to the ECU is bad, or youve got a faulty sensor
