The air flow sensor, also called air flow meter, is one of the important sensors of the EFI engine. It converts the inhaled air flow into an electrical signal and sends it to the electronic control unit (ECU). As one of the basic signals for determining fuel injection, it is a sensor that measures the air flow into the engine.

Mass Air Flow maf sensor for ford mustang 8V21 12B579 AA which made of high quality material, and through strictly perfect test then pack up sent out to customer.

The air flow sensor is installed between the air filter and the throttle body and is used to detect the intake air volume of the engine. It is one of the sources of basic control parameters of the electronic control system and an important component of the electronically controlled engine.

The function of the air flow sensor is to detect the amount of engine air intake, and convert the intake air amount information into electrical signals through circuit connections and input them to the ECU, so that the ECU can determine the fuel injection amount and ignition time. The intake air volume signal obtained by the air flow sensor is the main basis for the ECU to perform fuel injection control. If it is damaged or its circuit connection fails, the engine's intake air volume measurement will be inaccurate, causing the mixture entering the cylinder to be too rich or too rich. Too lean, causing the ECU to be unable to accurately control the fuel injection amount, causing the engine to not operate normally and exhaust emissions to exceed standards.
