Airflow Meter

Airflow meter measures intake airflow volume. Airflow meter delivers intake air input signal by means of a variable resistor (potentiometer).

Input signal is sent to Engine Control Module (ECM) for controlling fuel injection system operation and ignition timing (spark advance). Airflow meter also contains a switch which is used for controlling fuel pump operation.
