P227D Buick Code - Barometric Pressure Sensor 2 Circuit High Voltage
Quick Answer
The Barometric Pressure (BARO) Sensor 2, also referred to as the Turbocharger Inlet Air Pressure (TCIAP) sensor, is integral to the Multifunction Intake Air Sensor and is used for humidity sensor signal correction. Common causes include Faulty Multifunction Intake Air Sensor, Multifunction Intake Air Sensor harness is open or shorted, Multifunction Intake Air 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.
