The intake air temp sensor is part of the MAF sensor so yes there are 5 wires.
The two wires that go to the air temp sensor are tan and black. The other three are for the MAF.

SOURCE: IAT and MAF info

I have the same "chip" (really just a resistor). It should be the wire harness that clips into the lower box of the intake. I believe it is a green and a black wire. Just unclip it and slide the end of the resistor into each wire prong. Then tape the heck out of it. I put a rubber cap over mine then electrical tape. Works like a charm

SOURCE: wire colors for my IAT sensor

red with blue stripe and black... cut the red with blue strip and connect one end of the resistor to the harness side. Then splice the other end of the resistor to the black wire... do not cut it just splice into it.

This sensor is a resistor based sensor which detects the intake air temperature. According to the intake air temperature reading the ECM/PCM will control the necessary amount of fuel injection.

ECM = Engine Control Module (aka "the car's computer")
PCM = Powertrain Control Module (aka "the car's computer")

IAT SENSOR


what do you mean by control? there is one wire normally pink or white with pink strip that is power 5 volts + black is ground and a reference voltage 5 volts ground is black or white so the other two colors would be the control wires going to the computer. However would need the first 8 numbers of the Vin to know for sure. you can also go to www.alldatadiy.com and purchase a subscription that will give you the exact information you need, they change color codes for wires from time to time and if you hook it up wrong you can destroy the computer so I suggest you purchase the subscription to be sure.

2007 GMC Yukon IAT sensor


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.
Good Luck

2007 GMC Yukon. Can't locate the MAT or IAT sensor.


IAT is incoming air temperature sensor. Look from intake air hose/duct up to throttle body, for sensor that sticks into side or top of ducting that airflow coming in through there, or at front of throttle body area.
