The intake air temperature sensor is mounted to the intake air duct.
The intake air temperature 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. This sensor is not directly used to control the engine system. It is used on for the on-board diagnostics.
The resistance of the intake air temperature sensor should be:
