Air Flow Meter/Sensor: Description and Operation

Air Flow Meter/Air Intake Sensor:

The intake air flow is determined from a signal produced by a potentiometer in the air flow meter. The potentiometer is connected to the measuring flap. As air is drawn into the engine, the flap is deflected which causes the wiper contact of the potentiometer to move. The potentiometer signal represents the air volume entering the engine.
