The mass air flow sensor in the BMW G20 continuously measures the volume and density of incoming air. This data is essential for the engine control unit (ECU) to precisely calculate fuel injection timing and quantity. A faulty sensor disrupts this balance, leading to reduced power, poor acceleration, and increased emissions—making timely replacement or calibration crucial for maintaining vehicle performance.
