Code P10B8 2016 Chevrolet Silverado Description
The P10B8 diagnostic trouble code for a 2016 Chevrolet Silverado indicates an issue with the Mass Air Flow (MAF) Sensor Barometric Pressure Sensor Signal Message Counter being incorrect in Bank 2. The Mass Air Flow Sensor measures the amount of air entering the engine to determine the correct air-fuel mixture for combustion. The Barometric Pressure Sensor, on the other hand, measures the atmospheric pressure outside the vehicle. When the signal message counter for these sensors is incorrect in Bank 2, it means that the Engine Control Module (ECM) is receiving inconsistent or inaccurate data from these sensors in the second bank of the engine.
Common Causes of P10B8 2016 Chevrolet Silverado
- Faulty Mass Air Flow Sensor
- Faulty Barometric Pressure Sensor
- Wiring or connector issues
- ECM malfunction
- Air intake system leaks or restrictions
Symptoms of P10B8 2016 Chevrolet Silverado
- Check Engine Light illuminated
- Reduced fuel efficiency
- Rough idling or stalling
- Hesitation or lack of power
- Increased emissions
How to Fix P10B8 2016 Chevrolet Silverado
- Use an OBD-II scanner to retrieve the trouble codes and data related to the MAF and Barometric Pressure sensors.
- Inspect the wiring and connectors for any damage or corrosion. Repair or replace as necessary.
- Test the MAF and Barometric Pressure sensors using a multimeter to check for proper voltage and resistance values.
- If the sensors are faulty, replace them with OEM or high-quality aftermarket parts.
- Clear the trouble codes and perform a test drive to ensure the issue has been resolved.
Cost to Fix P10B8 2016 Chevrolet Silverado
The typical repair costs for addressing a P10B8 code on a 2016 Chevrolet Silverado can range from $200 to $500, including parts and labor.

Frequently Asked Questions about P10B8 2016 Chevrolet Silverado Code
1. What does the OBDII code P10B8 mean on a 2016 Chevrolet Silverado?
The P10B8 code indicates an issue with the Mass Air Flow (MAF) Sensor or Barometric Pressure Sensor on Bank 2, where the signal message counter is inconsistent or incorrect.
2. What are the common symptoms of the P10B8 code?
Symptoms may include reduced engine performance, poor fuel economy, rough idling, hesitation during acceleration, and an illuminated Check Engine Light.
3. What causes the P10B8 code to appear?
The code can be triggered by a faulty MAF sensor, a defective barometric pressure sensor, wiring or connector issues, or software-related communication errors in the Engine Control Module (ECM).
4. Can I drive my 2016 Chevrolet Silverado with the P10B8 code?
While it may be possible to drive the truck, it’s not recommended as it could lead to further engine performance issues or damage if left unresolved.
5. How do I diagnose the P10B8 code?
Diagnosis involves using an OBDII scanner to confirm the code, inspecting the MAF sensor and barometric pressure sensor for damage, checking the wiring and connectors, and testing sensor outputs for proper operation.
6. What is the role of the Mass Air Flow sensor in this issue?
The MAF sensor measures the amount of air entering the engine, and if its signal is incorrect or inconsistent, it can cause the P10B8 code to be triggered.
7. Can a dirty air filter cause the P10B8 code?
A dirty air filter is unlikely to directly cause this code, but it can indirectly affect the MAF sensor’s performance, leading to potential signal errors.
8. How can I fix the P10B8 code on my Silverado?
Repairs may include replacing the faulty MAF sensor or barometric pressure sensor, repairing damaged wiring or connectors, cleaning the MAF sensor, or reprogramming the ECM if needed.
9. What tools are needed to fix the P10B8 code?
You’ll need an OBDII scanner, a multimeter for electrical testing, basic hand tools for sensor replacement, and potentially MAF sensor cleaning spray.
10. How much does it cost to repair the P10B8 code on a 2016 Chevrolet Silverado?
The cost depends on the exact issue but typically ranges from $100 to $400, including parts and labor, with MAF sensor replacement being the most common repair.
