Intake Air Temperature Sensor: Description and Operation
Intake Air Temperature 2 (IAT2) Sensor
INTAKE AIR TEMPERATURE 2 (IAT2) SENSOR
Intake Air Temperature 2 (IAT2) Sensor
The IAT2 or manifold air temperature (MAT) sensor is a thermistor device. The electrical resistance of a thermistor decreases as the temperature
increases, and resistance increases as the temperature decreases. The varying resistance affects the voltage drop across the sensor providing a signal
corresponding to temperature.
The IAT2 sensor is located in the intake manifold. The sensor provides a manifold air temperature signal to the PCM. The PCM uses the IAT2 signal to
control timing and fuel rate during cold starts and provide an input to the cold idle kicker.
