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.
1 Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires. 2  Inspect for any air leaks near the MAF sensor. 3  Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. 4  Be gentle with the sensor.
