The Intake Air Temperature (IAT) Sensor (1,6,2) is integrated into the Mass Air Flow (MAF) Sensor. The IAT cannot be serviced separately. Refer to the MAF service procedures for removal. (Refer to FUEL SYSTEM/FUEL INJECTION/MANIFOLD AIR FLOW (MAF)  SENSOR - REMOVAL).

The IAT senses the inlet air temperature to the engine. The IAT then sends a signal to the Powertrain Control Module.
