P227D: Your Car’s Oxygen Sensor Needs Attention
The P227D fault code refers to the Barometric Pressure Sensor 2 Circuit High Voltage.
The sensor is part of the Multifunction Intake Air Sensor and is also known as the Turbocharger Inlet Air Pressure sensor. It responds to changes in altitude and atmospheric conditions, providing the Engine Control Module with an indication of intake air pressure relative to humidity. The DTC is triggered when the ECM detects that the BARO sensor pressure is greater than 115 kPa for more than 5 seconds.
FAQ
