Looking for Intake air temp. sensor on 04 6.0 gmc

Just thought I would add a picture.

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.

The IAT sensor(intake air temp sensor does just what it says it measure the intake air temperature and sends this signal to the computer, this is actually a minor input signal the more important one is the engine coolant temp sensor, the computer looks for a large deviation between the two sensors mainly when the engine is cold,if the temperatures are within a certain window the computer gives the ok to start the engine both sensors are input to the ECM but the IAT temp is only a small factor in air fuel mixture adjustment by the computer.

P0113 indicates the IAT Intake Temperature Sensor has a problem.
P0303 indicates a misfire on cylinder 3

I believe the IAT is built into the MAF sensor located in the air snorkle and helps regulate the air/fuel mixture. Also concentrate on cylinder 3 looking for problems such as injector, wiring, etc.

Hope this helps!

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

I assume you are looking for the wiring for the IAT because MAT sensors are no longer used..

here you go

black / white - PCM ground
pink - fused 12-volts
yellow - MAF signal
tan - IAT sensor signal
black - IAT sensor ground

manifold temp. sensors are no loner used.

I believe you are looking for the IAT "intake air temp sensor" which is part of the mass air flow sensor.

good luck

If your looking for the Intake Air Temp/Manifold Absolute Pressure sensor (IAT/MAP)(2003 model year and up) It is on the top of the intake manifold, just to the left of the #3 injector fuel line. There are 2 small Torx screws holding it.

IAT inlet air temp sensor is part of the MAF sensor. It is the 2 outside wires of the MAF conector

Its on the air duct behind the filter housing.

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.
