P2229 Honda Code - Barometric Pressure Sensor Circuit High Voltage
Quick Answer
The P2229 diagnostic trouble code refers to the Barometric Pressure Sensor Circuit High Voltage in Honda vehicles. Common causes include Faulty Barometric Pressure Sensor: A defective sensor can send incorrect signals to the ECM, leading to the high voltage in the sensor circuit, Damaged Wiring or Connectors: Corrosion, wear, or damage to the wiring or connectors in the sensor circuit can cause electrical issues and trigger the P2229 code, ECM Malfunction: A malfunctioning ECM can also be a potential cause of the high voltage in the barometric pressure sensor circuit. 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 Honda Description
The P2229 diagnostic trouble code refers to the Barometric Pressure Sensor Circuit High Voltage in Honda vehicles. The barometric pressure sensor is responsible for measuring the atmospheric pressure outside the vehicle. This information is crucial for the engine control module (ECM) to adjust fuel delivery and ignition timing, ensuring optimal performance and efficiency.
Common Causes of P2229 Honda
- Faulty Barometric Pressure Sensor: A defective sensor can send incorrect signals to the ECM, leading to the high voltage in the sensor circuit.
- Damaged Wiring or Connectors: Corrosion, wear, or damage to the wiring or connectors in the sensor circuit can cause electrical issues and trigger the P2229 code.
- ECM Malfunction: A malfunctioning ECM can also be a potential cause of the high voltage in the barometric pressure sensor circuit.
- Environmental Factors: Extreme changes in atmospheric pressure or temperature can sometimes affect the sensor readings and trigger the code.
Symptoms of P2229 Honda
- Check Engine Light: The most common symptom associated with the P2229 code is the illumination of the check engine light on the vehicle's dashboard.
- Decreased Fuel Efficiency: The vehicle may experience reduced fuel efficiency due to incorrect fuel delivery caused by the high voltage in the sensor circuit.
- Engine Performance Issues: The engine may exhibit rough idling, hesitation, or poor acceleration as a result of the incorrect sensor readings.
- Emission Problems: The vehicle may fail emissions tests due to increased emissions caused by the malfunctioning barometric pressure sensor.
How to Fix P2229 Honda
- Diagnose the Issue: Use a diagnostic scanner to retrieve the trouble codes and perform a thorough inspection of the barometric pressure sensor circuit to identify the root cause of the high voltage.
- Replace the Barometric Pressure Sensor: If the sensor is found to be faulty, replace it with a new, OEM-quality sensor to ensure accurate readings and proper functionality.
- Check Wiring and Connectors: Inspect the wiring and connectors in the sensor circuit for any damage, corrosion, or loose connections. Repair or replace as needed.
- Reset the ECM: Clear the trouble codes from the ECM and perform a reset to ensure that the new sensor and any repaired components are properly calibrated.
- Test Drive and Monitor: After completing the repair process, test drive the vehicle to ensure that the issue has been resolved. Monitor the sensor readings and check for any recurring trouble codes.
Cost to Fix P2229 Honda
The typical repair costs for addressing the P2229 code in a Honda vehicle can range from $150 to $400, including parts and labor. However, the actual cost may vary depending on the specific make and model of the vehicle, the location of the repair shop, and the extent of the repairs needed. It's recommended to consult with a qualified mechanic or auto repair shop for a more accurate estimate based on the individual circumstances. Additionally, factors such as diagnosis time and labor rates can impact the overall cost, with rates ranging from $80 to $150 per hour at most auto repair shops.
