Code P1415 BMW Description

Depending on engine speed, valve-lift, inlet camshaft position, outlet camshaft position, and manifold pressure an air mass flow into the cylinder is calculated. There is also a correction of the calculated air mass flow depending on intake air temperature, coolant temperature, and ambient pressure. The ratio between the measured air mass flow and the calculated air mass flow must be between adjustable MIN/MAX-values. If the MIN/MAX thresholds are exceeded, a time counter is incremented. After this counter reaches the threshold within one diagnosis cycle, an air mass flow meter malfunction is detected. The Diagnostic Trouble Code (DTC) sets when the Mass Air Flow Sensor signal value is too low.
