Airflow Meter

Airflow meter measures intake airflow volume. Input signal for airflow volume is sent from airflow meter to Engine Control Module (ECM) and may be used for controlling fuel injection system operation and ignition timing (spark advance).

NOTE: Airflow meter also contains an intake air temperature sensor which is used to measure intake air temperature. See INTAKE AIR TEMPERATURE SENSOR under INPUT DEVICES .
