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.
A mass air flow sensor is installed between the air filter and the intake manifold of the engine. The main job of the mass air flow sensor is to measure the amount of air entering the engine or air flow. Often an intake air temperature sensor (IAT) is also installed within the mass air flow sensor. There are few types of air flow sensors, however most modern cars use a hot-wire type. Let's see how it works.
