Intake Air Temperature Sensor: Description
The Intake Air Temperature sensor (IAT) (1,6,2) is integrated into the Mass Air Flow sensor (MAF). The IAT cannot be serviced separately. Refer to the MAF service procedures for removal. See MANIFOLD AIR FLOW (MAF) SENSOR .
The IAT senses the inlet air temperature to the engine. The IAT then sends a signal to the Powertrain Control Module (PCM).
