Intake Air Temperature Sensor: Description and Operation
IAT SENSOR
Component Description
The intake air temperature sensor is mounted to the air duct housing. The sensor detects intake air temperature and transmits a signal to the ECM.
The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. Electrical resistance of the thermistor decreases in
response to the temperature rise.
