Air Flow Meter/Sensor: Description and Operation
Air Flow Meter
PURPOSE
The airflow meter measures intake air volume, and converts these readings into voltage signals by means of a variable resistor (potentiometer).
These voltage signals are then sent to the ECM and used to determine injection duration and proper fuel delivery.
LOCATION
Mounted in the air induction system near the air cleaner.
OPERATION
When intake air volume is low, the voltage is high. When the intake air volume is high, the voltage signal is approximately zero.
