The voltage should be around 5 volts. If the voltage is not present, you may have a wiring or connector issue. Next, measure the voltage between Pin 1 (Signal) and Pin 3 (Ground) of the IAT sensor.The wires need to be in the same direction. So if you look at the other connector make sure the wires are on the correct side. Ask Your Own Medium and Heavy Trucks Question.
