What Does an Air Flow Meter Do?

The Mass Air Flow (MAF) Sensor measures the volume and density of air entering the engine, providing the engine control unit (ECU) with critical data about air mass. The ECU uses this information to calculate the optimal air-fuel mixture and adjust fuel injection accordingly. Accurate air flow measurement is essential for optimal engine performance, fuel efficiency, and emissions control. A properly functioning air flow meter ensures your engine receives the precise amount of fuel needed for complete combustion.
