Code P2229 2017 Chevrolet Silverado Description
The P2229 diagnostic trouble code (DTC) on a 2017 Chevrolet Silverado indicates a problem with the Barometric Pressure Sensor Circuit registering high voltage. The Barometric Pressure Sensor is a crucial component of the vehicle's engine management system, responsible for measuring the atmospheric pressure and providing this data to the engine control module (ECM). The ECM uses this information to calculate air density and adjust the fuel mixture for optimal combustion efficiency.
Common Causes of P2229 2017 Chevrolet Silverado
- Faulty Barometric Pressure Sensor
- Damaged wiring or connectors in the sensor circuit
- ECM malfunction
- Vacuum leaks in the intake system
- Incorrectly installed or incompatible aftermarket parts
Symptoms of P2229 2017 Chevrolet Silverado
- Decreased fuel efficiency
- Rough idling or engine misfires
- Hesitation or lack of power during acceleration
- Engine stalling
- Check Engine Light illuminated on the dashboard
How to Fix P2229 2017 Chevrolet Silverado
- Begin by diagnosing the issue using a scan tool to retrieve the specific DTC and verify the high voltage reading from the Barometric Pressure Sensor.
- Inspect the sensor, wiring, and connectors for any visible damage or corrosion. Replace any damaged components.
- Test the Barometric Pressure Sensor using a multimeter to ensure it is functioning within specifications. Replace if necessary.
- Clear the DTC from the ECM memory and perform a test drive to verify that the issue has been resolved.
- If the problem persists, further diagnostic testing may be required to identify any underlying issues with the ECM or other components.
Cost to Fix P2229 2017 Chevrolet Silverado

Frequently Asked Questions about P2229 2017 Chevrolet Silverado Code
1. What does the OBDII code P2229 mean on a 2017 Chevrolet Silverado?
P2229 indicates that the Barometric Pressure (BARO) sensor circuit is reading a voltage higher than the expected range.
2. What are common symptoms of code P2229 in a 2017 Chevrolet Silverado?
Symptoms may include poor engine performance, reduced fuel efficiency, hard starting, or the Check Engine Light being illuminated.
3. What causes the P2229 code in a 2017 Chevrolet Silverado?
Common causes include a faulty BARO sensor, damaged wiring or connectors, a malfunctioning Engine Control Module (ECM), or barometric pressure inconsistencies.
4. Is it safe to drive a 2017 Chevrolet Silverado with a P2229 code?
While the vehicle may still be drivable, it can experience performance issues. Prolonged driving with this issue could lead to further engine complications.
5. How do I diagnose the P2229 code on a 2017 Chevrolet Silverado?
Start by inspecting the BARO sensor and its wiring for damage or corrosion. Use a scan tool to monitor BARO sensor readings and compare them to expected values.
6. Can a dirty air filter cause the P2229 code on a 2017 Chevrolet Silverado?
While unlikely, a severely clogged air filter could indirectly affect engine performance and sensor readings. It’s worth checking during diagnosis.
7. How do you fix the P2229 code on a 2017 Chevrolet Silverado?
Repairs may involve replacing the BARO sensor, repairing damaged wiring, cleaning connections, or reprogramming the ECM if necessary.
8. Where is the BARO sensor located on a 2017 Chevrolet Silverado?
The BARO sensor is typically integrated into the MAP sensor or located near the intake manifold, depending on the engine configuration.
9. What tools are needed to fix the P2229 code on a 2017 Chevrolet Silverado?
You’ll need a scan tool, multimeter, and possibly basic hand tools for accessing and replacing the BARO sensor or repairing wiring.
10. Can a faulty MAP sensor trigger the P2229 code on a 2017 Chevrolet Silverado?
Yes, since the MAP sensor may share functionality or data with the BARO sensor, a malfunctioning MAP sensor could contribute to this code.
