Intake Air Temperature Sensor: Description and Operation
PURPOSE
The Intake Air Temperature Sensor is a temperature sensitive resistor (thermistor) which is mounted in the intake manifold to monitor intake
charge temperature.
OPERATION
Thermistor resistance decreases as the intake air temperature increases. This signal is used by the Engine Control Module (ECM) to determine
intake air density (oxygen content) for mixture control.
