The P14B6 code indicates that the Mass Air Flow (MAF) sensor signal message counter is incorrect, meaning the communication between the MAF sensor and the engine control module (ECM) is disrupted or inconsistent.
2. What are the common symptoms of the P14B6 code in a 2015 Chevrolet Silverado?
Symptoms may include poor engine performance, rough idling, reduced fuel efficiency, hesitation during acceleration, and the Check Engine Light being illuminated.
3. What causes the P14B6 code in a Chevrolet Silverado?
Common causes include a malfunctioning MAF sensor, damaged or corroded wiring, a faulty ECM, or communication errors between the MAF sensor and the ECM.
4. Can a dirty air filter cause the P14B6 code?
While a dirty air filter can restrict airflow and affect engine performance, it is unlikely to directly cause the P14B6 code. However, it’s still good practice to check and replace a dirty air filter.
5. How do you diagnose the P14B6 code on a 2015 Chevrolet Silverado?
Diagnosis typically involves scanning the ECM for codes, inspecting the MAF sensor and its wiring for damage, checking for loose connections, and testing the sensor’s output signals with a multimeter or diagnostic tool.

While the vehicle may still be drivable, ignoring the P14B6 code can lead to decreased engine performance, higher fuel consumption, and potential damage to other components over time.
7. How do you fix the P14B6 code on a Chevy Silverado?
Repairs may include cleaning or replacing the MAF sensor, repairing or replacing damaged wiring or connectors, or updating/replacing the ECM if necessary.
8. Can a software update fix the P14B6 code?
In some cases, a software update for the ECM may resolve communication issues that trigger the P14B6 code. Consult with a dealership or qualified technician to confirm.
9. How much does it cost to repair the P14B6 code?
Repair costs can vary widely—cleaning a MAF sensor may cost under $50, while replacing the sensor or repairing wiring could range from $200 to $500. ECM replacement or reprogramming might be more expensive.
