Well im not sure why you are asking this question . They are two differant systems the mas air flow and the idle air intake bolth run off a 5 volt referance voltage but are not related so to speak to each other as far as the same ref voltage the same ground as every thing else .The IAT MAP TP ECT and fuel pressure sensor are one side and the MAF EGR and the EVAP are on the other side but all on a common ground . Ex plain what you are trying to do and why you are trying to do it and mabey i can make your life a little easyer and what caused this problem

Where is the MAF/IAT sensor on a 2004 Chevrolet Silverado ?


You Tube Video--always go there,always

Google--always use that & read what is in print, for decades

In or on the intake plastic ducting between the air
filter box & the throttle body on ALL (98%) of vehicles
you can find the MAF,follow the wires

I would guess 90% have the IAT also inside & part of the maf

My maf sensor pigtail was cut and stolen. I purchased a new pigtail from ford and I need to know the color codes so I can intall a new one. my vehicle is a 2004 ford f-150 lariat with a 5.4 liter engine....


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.

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 MAFS and IAT are in a single connector on the 04-08 MY F-150s.
This is for a new body style 2004, not the Heritage / Lightning models.

The IAT sensor is the Gray w/ Red stripe & Gray wire pairs in the connector. The connector is a 6 pin ( 1 row of 6 pins ) black connector.
