Code P2229 Subaru Description
The P2229 Subaru code indicates that there is a high voltage condition detected in the Barometric Pressure Sensor circuit. The Barometric Pressure Sensor is responsible for measuring the atmospheric pressure and providing this information to the engine control module (ECM). This data is crucial for the ECM to calculate the optimal air-fuel mixture for combustion in the engine. When the voltage in the circuit is higher than normal, it can lead to incorrect readings being sent to the ECM, resulting in poor engine performance and efficiency.
Common Causes of P2229 Subaru
- Faulty Barometric Pressure Sensor
- Damaged wiring or connectors in the sensor circuit
- Issues with the ECM
- Vacuum leak in the intake system
- Poor electrical connections
Symptoms of P2229 Subaru
- Illuminated check engine light
- Rough idling
- Engine stalling
- Decreased fuel efficiency
- Engine hesitation
How to Fix P2229 Subaru
- Use a diagnostic scanner to retrieve the fault code and identify the specific issue with the Barometric Pressure Sensor circuit.
- Inspect the sensor, wiring, and connectors for any signs of damage or corrosion. Replace any faulty components.
- Check for any vacuum leaks in the intake system and repair as necessary.
- Clear the fault code from the ECM's memory and perform a test drive to ensure the issue has been resolved.
Cost to Fix P2229 Subaru
The cost of repairing a high voltage condition in the Barometric Pressure Sensor circuit can vary depending on the specific cause of the issue. In general, the cost of parts for this repair can range from $50 to $200, while the labor cost can range from $100 to $300. Overall, the total repair cost can be anywhere from $150 to $500. It is recommended to consult with a professional mechanic to get a more accurate estimate based on the specific circumstances of your vehicle. Keep in mind that labor rates and parts prices can vary based on location and the type of repair shop.
