An Air Flow Meter, AFM or Air Mass Meter, AMM measures the air flow or air mass that is drawn into the intake of the engine. This measurement is transmitted as a frequency or a variable voltage to the ECM, ECU, or PCM so that it can calculate the correct amount of fuel to deliver via the injectors in relation to the air going into the engine. Other terms used for this sensor are: MAF Sensor, Mass Air Flow Sensor, or Karmen Vortex AFM.

Various designs have been used over the years by different manufacturers to measure the air delivery to the engine, including vane or flap, hotwire, hot film, membrane and karmen vortex type to name just a few.
