Code P2228 2017 GMC Sierra Description
The P2228 diagnostic trouble code (DTC) for a 2017 GMC Sierra indicates that the barometric pressure sensor circuit is registering a low voltage. The barometric pressure sensor plays a crucial role in the vehicle's engine management system by measuring the atmospheric pressure and providing this data to the engine control module (ECM). This information is essential for determining the correct air-fuel mixture for combustion, optimizing engine performance, and ensuring fuel efficiency.
Common Causes of P2228 2017 GMC Sierra
- Faulty barometric pressure sensor
- Wiring issues or poor connections
- Corrosion in the sensor circuit
- ECM malfunction
- Environmental factors affecting sensor performance
Symptoms of P2228 2017 GMC Sierra
- Reduced engine performance
- Poor fuel efficiency
- Rough idling or stalling
- Hesitation during acceleration
- Illuminated check engine light
How to Fix P2228 2017 GMC Sierra
- Begin by performing a visual inspection of the barometric pressure sensor and its wiring harness to check for any visible damage, corrosion, or loose connections.
- Use a multimeter to test the sensor's voltage output and compare it to the manufacturer's specifications to determine if the sensor is functioning correctly.
- If the sensor is faulty, replace it with a new OEM sensor and ensure proper installation.
- Check and repair any damaged wiring or connections in the sensor circuit.
- Clear the DTC using a scan tool and perform a test drive to verify that the issue has been resolved.
Cost to Fix P2228 2017 GMC Sierra
The typical repair costs for addressing a barometric pressure sensor circuit low voltage issue can vary depending on the specific cause of the problem and the cost of parts and labor. In general, replacing the sensor and addressing any wiring issues may cost between $150 to $300, including parts and labor. However, it's important to note that diagnostic time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. It's advisable to check with local repair shops for a more accurate estimate based on your specific situation.

Frequently Asked Questions about P2228 2017 GMC Sierra Code
1. What does the OBDII code P2228 mean on a 2017 GMC Sierra?
P2228 indicates that the Barometric Pressure (BARO) Sensor Circuit is detecting a low voltage, which suggests an issue with the sensor or its circuit.
2. What are the common symptoms of the P2228 code on a 2017 GMC Sierra?
Symptoms may include poor engine performance, reduced fuel efficiency, difficulty starting, and the Check Engine Light being illuminated.
3. What causes the P2228 code to appear on a GMC Sierra?
Possible causes include a faulty barometric pressure sensor, damaged wiring or connectors, a defective Engine Control Module (ECM), or a sensor circuit short.
4. Can I drive my 2017 GMC Sierra with the P2228 code?
While the vehicle may still be drivable, it’s not recommended as it can lead to reduced performance, potential stalling, and further engine issues if left unresolved.
5. How do I diagnose the P2228 code on a 2017 GMC Sierra?
Start by checking the barometric pressure sensor and its wiring for damage or corrosion. Use a multimeter to test sensor voltage and compare it to manufacturer specifications.
6. How is the P2228 code fixed on a 2017 GMC Sierra?
Repairs may include replacing the barometric pressure sensor, repairing or replacing damaged wiring or connectors, or reprogramming/replacing the ECM if necessary.
7. How much does it cost to repair the P2228 code on a GMC Sierra?
Replacing the barometric pressure sensor typically costs between $100 and $300, depending on parts and labor. Wiring repairs or ECM replacement may increase the cost.
8. Can a dirty air filter cause the P2228 code?
No, a dirty air filter is unlikely to cause this code. The issue is specific to the barometric pressure sensor and its circuit.
9. Is the barometric pressure sensor the same as the MAP sensor?
No, while they are similar, the barometric pressure sensor measures atmospheric pressure, while the MAP sensor measures intake manifold pressure.
10. How can I prevent the P2228 code from recurring?
Regularly inspect and maintain the vehicle’s sensors, wiring, and connectors to prevent damage or corrosion. Address any Check Engine Light warnings promptly.
