Air Temperature Sensor ( Ambient / Intake ): Description and Operation

COMPONENT PARTS


Intake Air Temperature Sensor






The intake air temperature sensor is built-into the mass air flow sensor (1). 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 rise in temperature.
