P2229 2014 Chevrolet Silverado Code - Barometric Pressure Sensor Circuit High Voltage
Quick Answer
The Barometric Pressure (BARO) sensor is integral to the multifunction intake air sensor and responds to changes in altitude and atmospheric conditions. Common causes include Faulty Barometric Pressure (BARO) Sensor (integrated within Mass Air Flow/Multifunction Intake Air Sensor), Barometric Pressure Sensor harness is open or shorted, Barometric Pressure Sensor circuit poor electrical connection. 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.

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.
