Code P2229 RAM Description
The P2229 diagnostic trouble code (DTC) indicates that there is an issue with the Barometric Pressure Sensor 'A' Circuit being too high. The Barometric Pressure Sensor is responsible for measuring the atmospheric pressure outside the vehicle, which is used by the engine control module (ECM) to determine the correct air-fuel mixture for optimal engine performance. When the sensor detects a high circuit voltage, it means that the pressure reading is outside of the normal range, which can lead to a variety of issues with the vehicle's performance.
Common Causes of P2229 RAM
- Faulty barometric pressure sensor.
- Damaged sensor wiring harness.
- Poor electrical connection.
- ECM malfunction.
- Environmental factors affecting barometric pressure readings.
Symptoms of P2229 RAM
- Check engine light illuminated on the dashboard.
- Decreased engine performance, such as reduced power or acceleration.
- Rough idling or engine misfires.
- Poor fuel efficiency.
- Stalling or difficulty starting the engine.
How to Fix P2229 RAM
- Use a diagnostic scan tool to retrieve the trouble code and verify the issue with the barometric pressure sensor.
- Inspect the sensor wiring harness for any damage or corrosion and repair or replace as needed.
- Check the electrical connection to the sensor and ensure it is secure and free of debris.
- Test the barometric pressure sensor using a multimeter to determine if it is faulty and replace if necessary.
- Clear the trouble code from the ECM's memory and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P2229 RAM
The cost of repairing a P2229 code can vary depending on the root cause of the issue and the specific vehicle make and model. Generally, the cost of replacing a barometric pressure sensor can range from $100 to $300, including parts and labor. Additional costs may be incurred if there are wiring harness or electrical connection issues that need to be addressed. It is recommended to consult with a qualified mechanic or auto repair shop to get an accurate estimate based on your vehicle's specific needs. Keep in mind that labor rates and diagnostic fees can vary, so it's advisable to inquire about these costs upfront.

Frequently Asked Questions about P2229 RAM Code
1. What does the OBDII code P2229 mean on a RAM vehicle?
P2229 indicates that the Barometric Pressure Sensor 'A' circuit is reporting a voltage reading that is higher than the expected range.
2. What are the common symptoms of code P2229 in a RAM?
Symptoms may include poor engine performance, reduced fuel efficiency, difficulty starting, and the Check Engine Light being illuminated.
3. What causes the P2229 code to trigger in a RAM vehicle?
Common causes include a faulty barometric pressure sensor, wiring issues like shorts or open circuits, or a malfunctioning Engine Control Module (ECM).
4. Can a dirty air filter cause the P2229 code on a RAM?
A dirty air filter is unlikely to directly cause P2229, but it can contribute to air intake issues that might compound sensor problems.
5. How is the P2229 code diagnosed on a RAM?
A technician will use a scan tool to read live sensor data, inspect the barometric pressure sensor and wiring, and compare readings with the expected range for the current altitude.
6. Is it safe to drive a RAM with a P2229 code?
While it may be possible to drive, the vehicle could experience reduced performance and fuel efficiency. Prolonged driving with this issue may cause further damage.
7. How do you fix the P2229 code on a RAM?
Common fixes include replacing the barometric pressure sensor, repairing or replacing damaged wiring, and in rare cases, reprogramming or replacing the ECM.
8. Where is the barometric pressure sensor located on a RAM?
The barometric pressure sensor is typically integrated into the ECM or located near the intake manifold, depending on the specific model and engine.
9. Can a bad MAP sensor cause the P2229 code in a RAM?
Yes, if the MAP sensor and barometric pressure sensor share circuits or data, a faulty MAP sensor could contribute to the P2229 code.
10. Will clearing the code fix the P2229 issue on a RAM?
Clearing the code may temporarily turn off the Check Engine Light, but the underlying issue must be addressed to prevent the code from returning.
