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.
