P2228 2014 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 2014 GMC Sierra Code
1. What does the OBDII code P2228 mean for a 2014 GMC Sierra?
P2228 indicates a "Barometric Pressure Sensor Circuit Low Voltage," meaning the sensor is detecting a voltage level outside the expected range for atmospheric pressure.
2. What are common symptoms of the P2228 code in a 2014 GMC Sierra?
Common symptoms include poor engine performance, rough idling, decreased fuel efficiency, difficulty starting the engine, and potential illumination of the check engine light.
3. What causes the P2228 code to appear in a 2014 GMC Sierra?
Causes may include a faulty barometric pressure sensor, damaged wiring or connectors, a malfunctioning powertrain control module (PCM), or an electrical short in the circuit.
4. Can a dirty air filter trigger the P2228 code?
No, a dirty air filter is unrelated to the barometric pressure sensor and is unlikely to cause the P2228 code.
5. How do I diagnose the P2228 code in my 2014 GMC Sierra?
Start by using an OBDII scanner to confirm the code, then inspect the barometric pressure sensor, wiring, and connectors for physical damage or corrosion. Test the sensor voltage and continuity with a multimeter.
6. Can I drive my 2014 GMC Sierra with the P2228 code?
While the vehicle may still run, driving with this code can lead to poor performance and potential damage to the engine or other systems over time. It’s best to address the issue promptly.
7. How do I fix the P2228 code on a 2014 GMC Sierra?
Repairs may involve replacing the barometric pressure sensor, repairing or replacing damaged wiring, cleaning corroded connectors, or reprogramming or replacing the PCM if necessary.
8. What tools are needed to fix the P2228 code?
You’ll need an OBDII scanner, a multimeter for voltage testing, and basic hand tools for replacing components and repairing wiring.
9. How much does it cost to repair the P2228 code in a 2014 GMC Sierra?
Costs vary, but replacing the barometric pressure sensor typically ranges from $100 to $300, including parts and labor. Wiring repairs or PCM replacement may cost more.
10. Can a faulty PCM cause the P2228 code to appear?
Yes, a malfunctioning PCM can misinterpret or fail to process the barometric pressure sensor's signal, leading to the P2228 code. However, this is less common than sensor or wiring issues.
