Intake Air Temperature Sensor: Description and Operation
Intake Air Temperature Sensor
The Intake Air Temperature (IAT) sensor changes resistance in response to changing intake air temperature. The IAT sensor resistance decreases as the
air temperature increases, providing a signal to the Powertrain Control Module (PCM) indicating temperature of the incoming intake air.
