The mass air flow sensor, sometimes known as a MAF sensor or air flow meter, is an electrical device designed to measure the flow of air entering the vehicle intake manifold.

The mass air flow sensor is an integral part of the vehicle engine management system and is normally located in the vehicle inlet piping between the air filter and the throttle body assembly.

The mass air flow sensor converts the measured air flow into an electrical output voltage or frequency signal enabling the ECU to accurately control air/fuel delivery.

Common symptoms of a faulty, worn or inoperable mass air flow sensor may include illumination of the engine check light, poor fuel consumption, fuel delivery problems, engine knock, poor engine performance, hesitation or stumble during acceleration or difficult starting.

The mass air flow sensor must be compatible with the vehicle engine management system, always refer to the vehicle application list to ensure correct part number selection.
