Intake Air Temperature Sensor (IAT)

WARNING: This page is about a different car, the 2005 Ford Pickup, 2005 Ford F550 Super Duty, 2005 Ford F450 Super Duty, and 2005 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The intake air temperature (IAT) sensor is a thermistor in which resistance changes with temperature. The electrical resistance decreases as the temperature increases. The IAT provides air temperature information to the PCM which is used to help determine transmission line pressure and shift scheduling.
