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.
Mass Air Sensors (MAF) - Automotive. The Mass Air Flow Sensor is probably the best way to measure. the amount of air an engine takes in (engine load). This sensor. not only measures the volume of air but also compensates for its. density as well. Ford, GM, and many imports are using engine. control systems based around this sensor.
