Code P2229 2009 Honda Accord Description
The P2229 code for a 2009 Honda Accord indicates a problem with the barometric pressure sensor circuit registering high voltage. The barometric pressure sensor is responsible for monitoring the atmospheric pressure and providing this data to the engine control module (ECM) to ensure optimal fuel delivery and ignition timing. When the sensor detects high voltage, it can lead to incorrect air-fuel mixture ratios, which can affect engine performance and emissions.
Common Causes of P2229 2009 Honda Accord
- Faulty barometric pressure sensor
- Damaged wiring or connectors
- ECM malfunction
- Vacuum leaks
- Air intake system issues
Symptoms of P2229 2009 Honda Accord
- Decreased fuel efficiency
- Rough idling or engine stalling
- Poor acceleration
- Check Engine Light illuminated
- Engine misfires
How to Fix P2229 2009 Honda Accord
- Diagnose the issue by checking the voltage output of the barometric pressure sensor using a multimeter.
- Inspect the wiring and connectors for any damage or corrosion, and repair or replace as necessary.
- Test the ECM to ensure it is functioning correctly and reprogram if needed.
- Check for vacuum leaks in the intake system and repair as necessary.
- Clear the diagnostic trouble codes and test drive the vehicle to verify that the issue has been resolved.

Frequently Asked Questions about P2229 2009 Honda Accord Code
1. What does the OBDII code P2229 mean on a 2009 Honda Accord?
P2229 indicates that the barometric pressure sensor circuit is detecting a voltage level higher than the expected range.
2. What are the common symptoms of code P2229 in a 2009 Honda Accord?
Symptoms may include poor engine performance, rough idling, reduced fuel efficiency, stalling, or the check engine light being illuminated.
3. What causes the P2229 code to appear in a 2009 Honda Accord?
Common causes include a faulty barometric pressure sensor, wiring issues like damaged or corroded connections, a malfunctioning PCM (Powertrain Control Module), or an incorrect sensor calibration.
4. Can a dirty air filter trigger the P2229 code?
While unlikely, a severely clogged air filter could affect airflow readings, but the code typically points to an issue with the barometric pressure sensor or its circuit.
5. How is the P2229 code diagnosed?
A technician will use a scan tool to check the sensor data, inspect the wiring and connectors for damage, and test the sensor's voltage output to ensure it is within specification.
6. Can I drive with the P2229 code on my 2009 Honda Accord?
Driving with this code may be possible, but it is not recommended as it can lead to poor performance, higher emissions, and potential damage to the engine or other components.
7. How do you fix the P2229 code on a 2009 Honda Accord?
Repairs may involve replacing the barometric pressure sensor, repairing damaged wiring, or reprogramming/updating the PCM if necessary.
8. Where is the barometric pressure sensor located on a 2009 Honda Accord?
The barometric pressure sensor is typically integrated into the PCM or mounted near the intake manifold, depending on the engine configuration.
9. How much does it cost to repair the P2229 code on a 2009 Honda Accord?
Repair costs can range from $100 to $300, depending on whether the issue is with the sensor, wiring, or PCM.
10. Can a faulty MAP sensor cause the P2229 code?
No, the MAP (Manifold Absolute Pressure) sensor and barometric pressure sensor are separate components, but issues with the MAP sensor could cause similar symptoms.
