P2228 Buick Code - Barometric Pressure Sensor Circuit Low Voltage
Quick Answer
The Barometric Pressure (BARO) sensor is integral to the multifunction intake air sensor and responds to changes in altitude and atmospheric conditions. Common causes include Faulty Barometric Pressure (BARO) Sensor (integrated within Mass Air Flow/Multifunction Intake Air Sensor), Barometric Pressure Sensor harness is open or shorted, Barometric Pressure Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
