Intake Air Temperature Sensor
WARNING: This page is about a different car, the 1993 Toyota MR2. However, it is still accessible from the selected car via links, so may be relevant.
An intake air temperature sensor is mounted in either airflow meter or air filter housing. Intake air temperature sensor measures incoming intake air temperature and delivers an input signal to THA terminal of Engine Control Module (ECM) to control fuel injection system. Input signal is also used to control fuel pressure control and heated oxygen sensor systems (if equipped).
