P2229 2008 Honda Accord Code - Barometric Pressure Sensor Circuit High Voltage
Quick Answer
The P2229 diagnostic trouble code (DTC) for a 2008 Honda Accord indicates that there is a high voltage condition in the barometric pressure sensor circuit. Common causes include Faulty Barometric Pressure Sensor: The sensor itself may be malfunctioning, sending a high voltage signal to the ECM, Wiring Issues: Corrosion, damage, or loose connections in the wiring harness connected to the barometric pressure sensor can cause high voltage readings, ECM Malfunction: A malfunctioning ECM may incorrectly interpret the sensor's signals, leading to a high voltage condition. 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 2008 Honda Accord Description
The P2229 diagnostic trouble code (DTC) for a 2008 Honda Accord indicates that there is a high voltage condition in the barometric pressure sensor circuit. The barometric pressure sensor is responsible for measuring the atmospheric pressure outside the vehicle, which is crucial for the engine control module (ECM) to adjust fuel delivery and ignition timing. When the sensor detects a high voltage signal, it means that the pressure reading is higher than expected, potentially leading to incorrect fuel-air mixture ratios and ignition timing. This can result in poor engine performance, reduced fuel efficiency, and increased emissions.
Common Causes of P2229 2008 Honda Accord
- Faulty Barometric Pressure Sensor: The sensor itself may be malfunctioning, sending a high voltage signal to the ECM.
- Wiring Issues: Corrosion, damage, or loose connections in the wiring harness connected to the barometric pressure sensor can cause high voltage readings.
- ECM Malfunction: A malfunctioning ECM may incorrectly interpret the sensor's signals, leading to a high voltage condition.
- Vacuum Leaks: Any vacuum leaks in the intake system can affect the barometric pressure sensor readings, causing the high voltage code.
- Sensor Calibration: Improper calibration of the sensor during installation or replacement can also trigger this code.
Symptoms of P2229 2008 Honda Accord
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
- Reduced Engine Performance: The vehicle may experience a lack of power, hesitation, or rough idling due to incorrect fuel delivery.
- Poor Fuel Efficiency: The high voltage condition can lead to inefficient combustion, resulting in decreased fuel economy.
- Emission Failures: The vehicle may fail emissions tests due to increased emissions caused by improper fuel-air mixture ratios.
- Rough Running: The engine may run rough or stall intermittently, especially during acceleration or deceleration.
How to Fix P2229 2008 Honda Accord
- Diagnose the Issue: Use a scan tool to retrieve the DTC and perform a thorough inspection of the barometric pressure sensor, wiring, and ECM.
- Test the Sensor: Check the sensor's voltage output using a multimeter to verify if it is within the specified range.
- Inspect Wiring: Inspect the wiring harness for any signs of damage, corrosion, or loose connections. Repair or replace as necessary.
- Check ECM Functionality: Test the ECM for proper operation and reprogram or replace if needed.
- Clear Codes: Clear the DTC using a scan tool after completing the repairs and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P2229 2008 Honda Accord
The cost of repairing a P2229 code on a 2008 Honda Accord can vary depending on the specific cause of the issue. On average, the parts cost for a new barometric pressure sensor ranges from $50 to $150, while labor costs can range from $80 to $150 per hour. In total, the repair for this issue may cost between $150 to $400, including parts and labor. However, it is recommended to consult with a qualified mechanic or auto repair shop for a more accurate estimate based on the vehicle's condition and location. Labor rates at auto repair shops can vary, so it's essential to inquire about specific rates before proceeding with the repair.

Except for the check engine light which is on, my honda accord 2004 is running well. The reading I got is P2229, and having read the symptoms, I don't get or feel that in the car. But of course, there's uncertainty because of the check engine light. Any comment is highly appreciated, I don't trust our honda dealers here in the Philippines, they only know mechanical and zero knowledge of the electronic side.
