P2228 2017 GMC Sierra Code - Barometric Pressure Sensor Circuit Low 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 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.
