P2229 OBD-II: Barometric Pressure Sensor "A" Circuit High
P2229 Severity
Should you fix P2229 yourself?
Identifying an OBD code is just the start of a complete diagnostic routine. Most trouble codes are caused by a sensor reporting a value that is out of range. Just replacing a sensor may not fix underlying issues. Be sure to understand the code, the part or system in your car that the code refers to, and the risks of delaying professional repair.
Proper diagnosis will save you time and money on unnecessary repairs.
Urgent codes indicate immediate action is necessary. These are urgent and significant malfunctions that can cause severe damage to the vehicle or harm the driver and passengers.
What causes OBD-II fault code P2229?
The Barometric Pressure Sensor monitors ambient air pressure. Most manufacturers have this sensor integrated into the Mass Airflow Sensor (MAF) or the Powertrain Control Module (PCM). The PCM compares this reading to other sensors to verify the Barometric Pressure Sensor's Calibration. If the PCM determines that the sensor has lost its calibration or voltage reading from the sensor is incorrect, the PCM will set code P2229.
