Intake Air Temperature Sensor: Description and Operation

Intake Air Temperature Sensor

Description

The IAT sensor is a temperature dependent resistor (thermistor), i.e. the resistance of the sensor varies with temperature. The thermistor is a NTC type
which means that the sensor resistance decreases as the sensor temperature increases. It is located between the MAF sensor and the throttle body.

A fault is detected if the resistance of the sensor exceeds a minimum or maximum threshold.
