Intake Air Temperature Sensor 1
WARNING: This page is about a different variant/trim than selected.
The intake air temperature sensor 1 (IAT sensor 1) is built-into the mass air flow sensor. 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.
