What Does an Air Flow Meter Do?

The Mass Air Flow (MAF) meter measures the volume and density of air entering the engine. This critical data allows the engine control unit (ECU) to calculate the precise amount of fuel needed for optimal combustion. In turbocharged applications, accurate airflow measurement is especially important for maintaining proper boost levels and preventing engine damage from running too lean or too rich.
