The intake air temp. sensor is actually part of the Mass Air Flow sensor on the air intake tube between the air filter and the throttle body.

For a 2005 GMC yukon 5.3L what are the wire colors that control the IAT sensor There should only be 2 wires controlling it but there are 5 on the connection as it controls the MAF and IAT with the sa

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.

Gs300 coolant is bubbling in resevoir,but temp is fine ?

Get coolant temp sensor checked.

Get the coolant pressure tested, its definitely leaking coolant. You will need to get the coolant running line.

Pressure test will help you to know from where exactly coolant/refrigerant is getting leaked.

Hello people i got a gmc 99 jimmy 2door sls the engine light keeps coming on then going out ive coded it to be an iat sensor and also says the iat sensor intermitten voltage high and then the knock sensor...

the IAT may be bad or the connector is bad, real common (friend should know to check that) get a real scanner and see what the IAT is reading, then move the connector and see if it changes. if it reads -40f then its bad or disconnected.

Replacing temp sensor

Intake Air Temperature Sensor Operation The Intake Air Temperature (IAT) sensor is a variable temperature sensitive resistor. Sensor resistance will change based on air temperature. The higher the temperature, the lower the resistance. The Engine Management System (EMS) provides a reference voltage and monitors the voltage drop between a fixed value internal resistance and the sensor resistance. This is called a voltage divider circuit.
IAT sensor values are used by the EMS to assist with the calculation of idle speed, fuel mixture and spark advance.
Inaccurate voltages from the IAT sensor may affect pulse-width, idle quality and tail pipe emissions. Intermittent signals may cause hesitation, stumble and surging. If an IAT sensor failure accompanies an Engine Coolant Temperature (ECT) sensor failure cooling fan operation may also be affected.
Some manufacturers' incorporate the Intake Air Temperature (IAT) sensor as part of the Mass Air Flow (MAF) sensor, or air flow meter. Refer to current service information for specific applications.
Related Symptoms The following symptoms can be caused by a faulty IAT sensor due to loose connections, bad grounds, high resistance in the circuit, or opens in the circuit.
  • Extended crank time when the engine is cold
  • Poor fuel economy
  • Spark knock

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.

Location of iat high input sensor

The iat (intake air temperature) is located on the air filter housing. If its reading high its probably unplugged

2007 gmc sierra 2500 IAT sensor

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.
