I have a 2008 Ford Expedition and I need to find the Intake Air Temperature switch. Can anyone help me with locating the switch on the engine?

A lot of times they are integrated in to the MAF. You should be able to find the IAT by simply follwing the intake. The sensor should be between the filter box and the throttle body. You may need to get a meter to verify the signal - it most likely won't be an on/off switch but more likely an analog voltage that represents the exact temp.

I finally went to the Ford dealership and they told me the same thing. Thanks for your help though.
