P2229 Ford Code - Barometric Pressure Sensor 'A' Circuit High
Quick Answer
The P2229 Ford diagnostic trouble code indicates that there is a high circuit condition in the Barometric Pressure Sensor 'A'. Common causes include Faulty Barometric Pressure Sensor: The sensor itself may be defective and sending incorrect signals to the ECM, Wiring Issues: Corroded, damaged, or loose wiring connections between the sensor and the ECM can cause a high circuit condition, ECM Malfunction: A malfunctioning ECM can misinterpret the sensor's signals, leading to the P2229 code. 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.

Code P2229 Ford Description
The P2229 Ford diagnostic trouble code indicates that there is a high circuit condition in the Barometric Pressure Sensor 'A'. This sensor is responsible for measuring the atmospheric pressure outside the vehicle, which is crucial for the engine control module (ECM) to accurately calculate the air-fuel mixture and ignition timing. When the signal from the barometric pressure sensor is too high, it can cause disruptions in the engine's performance and overall efficiency.
Common Causes of P2229 Ford
- Faulty Barometric Pressure Sensor: The sensor itself may be defective and sending incorrect signals to the ECM.
- Wiring Issues: Corroded, damaged, or loose wiring connections between the sensor and the ECM can cause a high circuit condition.
- ECM Malfunction: A malfunctioning ECM can misinterpret the sensor's signals, leading to the P2229 code.
- Vacuum Leaks: Any vacuum leaks in the intake system can disrupt the barometric pressure readings and trigger this code.
- Environmental Factors: Extreme weather conditions or changes in altitude can sometimes cause temporary high circuit conditions in the sensor.
Symptoms of P2229 Ford
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Fuel Economy: A high barometric pressure sensor circuit can cause the engine to run rich or lean, leading to decreased fuel efficiency.
- Rough Idle: The engine may experience rough idling or fluctuations in RPM due to inaccurate air-fuel mixture calculations.
- Engine Misfires: Misfires may occur as a result of incorrect ignition timing caused by the faulty barometric pressure sensor signal.
- Lack of Power: The engine may lack power during acceleration or struggle to reach higher speeds due to incorrect fuel delivery.
How to Fix P2229 Ford
- Diagnose the Issue: Use a diagnostic scanner to retrieve the trouble code and perform a thorough inspection of the barometric pressure sensor and related wiring.
- Replace the Sensor: If the sensor is found to be faulty, replace it with a new one and ensure proper calibration.
- Check Wiring Connections: Inspect the wiring harness for any signs of damage or corrosion, and repair or replace as necessary.
- Verify ECM Functionality: Test the ECM to ensure it is functioning correctly and interpreting sensor signals accurately.
- Clear Codes and Test Drive: Clear the trouble code from the ECM memory, and test drive the vehicle to verify that the issue has been resolved.
Cost to Fix P2229 Ford
The cost to repair a high circuit condition in the Barometric Pressure Sensor 'A' can vary depending on the specific vehicle make and model, as well as the location and labor rates of the auto repair shop. On average, the parts for a new barometric pressure sensor can range from $50 to $150, with additional costs for any necessary wiring repairs or ECM testing. Labor costs can range from $100 to $300, depending on the shop's hourly rates and the complexity of the repair. Overall, the total repair cost for this issue could be between $150 and $500. It's advisable to contact local auto repair shops for accurate pricing information.
