Intake Air Temperature Sensor

Intake Air Temperature (IAT) sensor is mounted on air duct housing. IAT sensor monitors temperature of incoming air. IAT sensor is a thermistor and increases (cold) or decreases (hot) its resistance in response to temperature changes. This input is only used for on-board diagnosis and is not used to control engine operation.
