Air Flow Meter/Sensor: Description and Operation
Basic
The mass air flow (MAF) sensor informs the PCM of the rate of air flow entering the engine by producing a voltage which is proportional to the rate of
air flow into the engine. The voltage produced by the MAF sensor increases as the rate of air flow increases. The MAF sensor also takes into account the
density of the air entering the air intake system so that it is possible to maintain the required air to fuel ratio, and to compensate for variations in
atmospheric pressure.
