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 majority of vehicles on the road today are equipped with a mass air flow sensor (MAF), also commonly referred to as an air flow meter. The mass air flow sensor is a device that measures the amount of air entering the engine and supplies this information to the engine control unit (ECU).ot Wire Mass Air Flow Sensors. One of the more common mass air flow sensors used today is the hot wire sensor. This type of MAF sensor measures air mass directly. It uses an electronic control unit, a temperature sensor, and an electronically heated wire(s).
