Question about 2007 GMC Yukon
I have located the sensor but it is part of the MAT sensor I think. 5 wires. 2 per sensor with a common black ground wire but which two wires are the IAT?
Are you aware you can't really test this without the correct impedance meter You can ohm the sensor. But you will need to see how it responds while the car is warming up and you will need an laser to test for temp. I'm just letting you know that these newer computer in cars can be damaged easily with the wrong meter.
