How does a maf sensor work
WebNov 25, 2024 · What Does a Mass Air flow Sensor Do? Your mass air flow sensor or “MAF” 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. WebAug 19, 2024 · How Does the MAF Sensor Work? The MAF sensor has one main purpose: to calculate the amount of air entering an engine. It’s usually located in the intake pipe, between the air filter housing and the intake manifold. MAF sensors are of two main types: hot wire (electrical), and vane meter (mechanical).
