Code P2229 2014 Chevrolet Silverado Description
The P2229 diagnostic trouble code (DTC) for a 2014 Chevrolet Silverado indicates a problem with the Barometric Pressure Sensor Circuit registering high voltage. The Barometric Pressure Sensor is a crucial component in the vehicle's engine management system, as it measures the atmospheric pressure to help determine the correct air-fuel mixture for combustion in the engine. When the sensor detects a high voltage signal, it means that the pressure reading is outside of the expected range, which can lead to various performance issues.
Common Causes of P2229 2014 Chevrolet Silverado
- Faulty Barometric Pressure Sensor
- Damaged wiring or connectors in the sensor circuit
- ECM malfunction
- Vacuum leaks in the intake system
- Incorrect sensor calibration
Symptoms of P2229 2014 Chevrolet Silverado
- Reduced fuel efficiency
- Rough idling or stalling
- Hesitation or lack of power during acceleration
- Engine misfires
- Difficulty starting the engine
How to Fix P2229 2014 Chevrolet Silverado
- Begin by conducting a thorough inspection of the Barometric Pressure Sensor, wiring, and connectors for any visible damage or corrosion.
- Test the sensor using a multimeter to check for proper voltage output within the specified range.
- If the sensor is faulty, replace it with a new OEM or high-quality aftermarket sensor.
- Clear the DTC from the vehicle's ECM using a diagnostic scan tool.
- Test drive the vehicle to ensure that the issue has been resolved and that the sensor is providing accurate readings.
Cost to Fix P2229 2014 Chevrolet Silverado
The typical repair costs for addressing a Barometric Pressure Sensor Circuit High Voltage issue in a 2014 Chevrolet Silverado can range from $100 to $300, depending on the specific cause of the problem and the cost of parts and labor.

Frequently Asked Questions about P2229 2014 Chevrolet Silverado Code
What does the OBDII code P2229 mean for a 2014 Chevrolet Silverado?
P2229 indicates that the Powertrain Control Module (PCM) has detected a high voltage signal from the Barometric Pressure (BARO) sensor circuit, suggesting an issue with the sensor or its associated components.
What are the symptoms of code P2229 in a 2014 Chevrolet Silverado?
Common symptoms include reduced engine performance, poor fuel efficiency, difficulty starting the engine, and the Check Engine Light being illuminated.
What causes the P2229 code to appear on a 2014 Chevrolet Silverado?
Possible causes include a faulty BARO sensor, damaged or corroded wiring, a poor electrical connection, or an issue with the PCM itself.
Can a dirty air filter cause the P2229 code on a 2014 Chevrolet Silverado?
No, a dirty air filter is unlikely to cause this code, as it pertains to the BARO sensor and not the airflow directly.
How do you diagnose the P2229 code on a 2014 Chevrolet Silverado?
Diagnosis typically involves using a scan tool to check sensor readings, visually inspecting the wiring and connectors, and testing the BARO sensor's voltage output against manufacturer specifications.
Can I drive my 2014 Chevrolet Silverado with a P2229 code?
Driving with a P2229 code is not recommended, as it can lead to poor performance, reduced fuel efficiency, and potential damage to the engine over time.
How do you fix the P2229 code on a 2014 Chevrolet Silverado?
Repairs may involve replacing the BARO sensor, repairing or replacing damaged wiring, cleaning corroded connectors, or reprogramming or replacing the PCM if necessary.
What tools are needed to fix the P2229 code on a 2014 Chevrolet Silverado?
You may need a scan tool, a multimeter for electrical testing, basic hand tools for sensor replacement, and possibly a PCM reprogramming tool.
How much does it cost to fix the P2229 code on a 2014 Chevrolet Silverado?
Repair costs vary depending on the issue but can range from $50 to $300 for sensor replacement and wiring repairs, or more if PCM replacement is required.
Is the Barometric Pressure (BARO) sensor the same as the MAP sensor in a 2014 Chevrolet Silverado?
No, the BARO sensor measures atmospheric pressure, while the MAP (Manifold Absolute Pressure) sensor measures pressure inside the intake manifold. However, some vehicles combine these functions into one sensor.
