Might be part of the mass airflow sensor assembly, all one piece.

Well, the IAT (Intake Air Temperature) sensor is located on the air intake duct between the filter and the throttle body (Assuming you have the 6L motor). The wires are easily visible at the plug that connects the sensor to the wiring harness. That's the easiest place to access them.

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.

2004 GMC Sierra 4dr truck. the fan does not work


The switch or the wire harness at the blower motor has gone bad. The highest setting 5 has no resistor, so the blower runs on high but the high current flow ends up burning up the switch's contact on that setting or the resistor wire harness at the blower motor has gone bad. Common would be the switch it self, if the switch is good. Then it's going to be the wire leads at the speed resistor by the blower motor under the glove box by the passenger leg compartment. Keep me posted, be glad to help you get your Sierra running 100% again soon.

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.
