P12A8 MINI Description
During the control module’s shutdown phase the diagnostic function monitors the barometric pressure sensor, intake-manifold sensor and the pressure sensor on the air-intake side of the throttle valve to determine whether they are all measuring the same pressure. The ECM sets the OBDII code when the Boost Pressure Sensor is not to factory specifications.
