Code P14B6 2016 GMC Sierra Description
The diagnostic trouble code P14B6 for a 2016 GMC Sierra indicates that there is an issue with the Mass Air Flow (MAF) Sensor Signal Message Counter being incorrect. The Mass Air Flow sensor is a crucial component of the vehicle's engine management system, responsible for measuring the amount of air entering the engine. This data is used by the engine control module (ECM) to calculate the correct air-fuel mixture for combustion, ensuring optimal performance and fuel efficiency.
Common Causes of P14B6 2016 GMC Sierra
- Faulty Mass Air Flow sensor
- Wiring issues or poor connections
- Dirty or contaminated MAF sensor
- ECM software or hardware issues
- Air intake system leaks or restrictions
Symptoms of P14B6 2016 GMC Sierra
- Decreased fuel efficiency
- Rough idling or stalling
- Engine hesitation or misfires
- Check Engine Light illuminated
- Reduced overall engine performance
How to Fix P14B6 2016 GMC Sierra
- Begin by diagnosing the issue using a scan tool to confirm the P14B6 code and check the MAF sensor's operation.
- Inspect the wiring and connections to the MAF sensor for any damage or corrosion, repairing or replacing as necessary.
- Clean the MAF sensor with specialized cleaner to remove any dirt or debris that may be affecting its performance.
- If cleaning does not resolve the issue, replace the MAF sensor with a new, OEM-quality part.
- Clear the diagnostic trouble codes from the ECM and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P14B6 2016 GMC Sierra

Frequently Asked Questions about P14B6 2016 GMC Sierra Code
1. What does the OBDII code P14B6 mean on a 2016 GMC Sierra?
P14B6 indicates that the Mass Air Flow (MAF) sensor signal message counter is incorrect, which means the Engine Control Module (ECM) is detecting an inconsistency in the MAF sensor data communication.
2. What are the common symptoms of code P14B6 in a 2016 GMC Sierra?
Common symptoms include reduced engine performance, poor fuel economy, rough idling, and possibly an illuminated check engine light.
3. What causes the P14B6 code to appear on a GMC Sierra?
The code can be caused by a faulty MAF sensor, wiring or connection issues in the MAF circuit, ECM software errors, or problems with the CAN (Controller Area Network) communication.
4. How can I diagnose the P14B6 code in my 2016 GMC Sierra?
Begin by checking the MAF sensor wiring and connectors for damage or corrosion. Inspect the sensor for dirt or debris and verify proper voltage and data signal using a multimeter or scan tool.
5. Can a dirty air filter trigger the P14B6 code?
While a dirty air filter can restrict airflow and affect MAF readings, it typically won't directly cause the P14B6 code. However, it's still a good idea to inspect and replace the air filter if necessary.
6. Is it safe to drive my GMC Sierra with the P14B6 code?
Driving with this code may lead to reduced engine performance and potentially cause further damage over time. It’s best to address the issue promptly to avoid complications.
7. How do I fix the P14B6 code on my 2016 GMC Sierra?
Repairs may include cleaning or replacing the MAF sensor, repairing damaged wiring or connectors, updating the ECM software, or addressing communication issues in the vehicle's network.
8. How much does it cost to fix the P14B6 code?
The cost depends on the root cause. Cleaning the MAF sensor may cost little to nothing, while replacing the sensor or repairing wiring can range from $100 to $400. ECM updates may require additional labor charges.
9. Can a bad MAF sensor cause other engine issues?
Yes, a faulty MAF sensor can cause improper air-fuel mixture readings, leading to misfires, stalling, or other performance problems.
10. How can I prevent the P14B6 code from occurring again?
Regularly inspect and clean the MAF sensor, replace the air filter as needed, and ensure the electrical connections and wiring remain in good condition.
