Code P2227 BMW Description

This fault code is stored in the engine control module when a malfunction is detected in the barometric pressure sensor circuit. The Engine Control Module (ECM) uses the barometric pressure sensor to monitor air pressure and hence air density. More dense air contains more oxygen particles, less dense air contains fewer oxygen particles. The engine fueling can be adjusted accordingly. The barometric pressure sensor can be a separate component sampling the atmospheric air pressure. Occasionally the component can be fitted internally within the engine control module.
