What Does a Mass Air flow Sensor Do? Your mass air flow sensor or âMAFâ detects the volume of air as it enters your engine by heating up a thin wire or resistor. The computer in your car then measures electrical resistance through the MAF as the air flowing through the sensor cools its components down. With a firm understanding of how much air is flowing into your engine, the computer can then direct fuel injectors to add more or less gasoline to the air/fuel mixture.
The Mass Airflow Sensor (MAF) measures the amount of air entering the engine and the Engine Control Module (ECM) uses the information to determine the proper amount of fuel quantity and ignition timing. Code P0102 sets when the ECM detects a low voltage output from the Mass Air flow Sensor.
