IAT sensor plug 2004 Ford F150...is it located seperately or is it integrated in the MAF plug? I see a separate set of two wires but I don't know? It's the standard 5.4 L V8 on my supercrew Lariat.

The Mass Air Flow (MAF) sensor/Intake Air Temperature (IAT) sensor is located in the air cleaner case.

The Intake Air Temperature (IAT) sensor is an integral part of the Mass Air Flow (MAF) sensor. Looks like this:

Hello mahnkes.

You did not mention what engine you have.
I have based this reply on a 6.0 liter gasoline engine.

The IAT (intake air temperature) is integral with the MAF that is mounted in the intake duct and if defective will need to be replaced as an assembly.
#2 in the diagram below.


I hope this helps you along.
Let me know if your engine isn't the 6.0

what motor do you have? If it's a 5.4 the IAT sensor is separate (gy/rd) signal return, (rd/wh) sig from PCM

As long as you are talking about the new body style ( 3V 5.4 L )

The module is the MAFS and the IAT sensors

The IAT section is :
PCM to IAT is Gray wire
The return to the electronic engine controls from the IAt is Gray w/ REd stripe wire

The MAFS
PCM to MAFS ( MAF ) is Light Blue w/ Red stripe wire
The MAF return on the PCM is Tan w/ Light Blue stripe wire
The ground ( same as the Charge motion control valve ) is Black w/ White stripe wire.

it's the sensor on the intake air duct come out of your air filter. the iat sensor is integrated with the maf sensor

It is mounted inside the MAF

The IAT is integrated with the MAF sensor on the 09 Fusion. The MAF is located near the air box on all three engines. on the driver's side, and will be held to some part of the intake tubing by 2 torx screws. http://media.photobucket.com/image/2009%20Fusion%20MAF/itsamecameron/fusion4cylengineMAF.jpg 2.3L shown, 3.0 and 3.5 should be similar.

both signals are at the far end of the plug iat is the gray wire maf is the gray with the red trace. let me know if this helps

the IAT is a small round sensor with 2 wire going to it, the sensor is located in the air filter housing lid or in the flexible air intake hose to the engine from the air cleaner box.

here is a picture

The IAT has been integrated with the MAF and cannot be accessed seperatley,
