where is the IAT?

[hazmat456]

Anybody know where the IAT is on a 2000 mountaineer with a 5.0, it is not on the intake and the truck has a p0112 code among others.
Funny thing is with the scanner hooked up the intake air temp seems to be reading fine. 93 degrees after a five minute warm up with a 75degree ambient temp.

The IAT is in the intake tube down stream from the MAF.

 

[hazmat456]

that's what I would have thought but it's not there.
There is nothing between the maf and the tps.

 

[hazmat456]

there is also no place for one on the plastic intake tube so it didn't fall out either,
could it be combined with the maf?

 

[Dan Whitaker]

How many pins does your MAF plug have? My '97 has 4. If you have 6 then I think the IAT might be combined with the MAF.

 

[hazmat456]

yeah it doesn't look anything like my 97'
this maf has quite a few wires but I won't know for sure until I go look at it again, I think it had at least 6

Integrated MAF/IAT sensor

You have an integrated MAF/IAT sensor. The outer pins on the 6 pin connector (E&F) are the ones for the IAT sensor. The Gray wire is the signal and the gray/red wire is the return which does not go to ground. It is common with other sensor returns (TPS, O2s, DPFE, etc.)
