Code P0108 2016 Chevrolet Silverado Description
The P0108 diagnostic trouble code (DTC) for a 2016 Chevrolet Silverado indicates a problem with the Manifold Absolute Pressure (MAP) sensor or Barometric Pressure (BARO) sensor circuit registering a high input. The MAP sensor measures the pressure inside the intake manifold, providing crucial data to the engine control module (ECM) for determining the correct air-fuel mixture for combustion. The BARO sensor, on the other hand, measures the atmospheric pressure outside the vehicle, helping the ECM adjust fuel delivery based on altitude changes.
Common Causes of P0108 2016 Chevrolet Silverado
- Faulty MAP sensor
- Faulty BARO sensor
- Wiring harness issues (corrosion, damage)
- Faulty ECM
- Vacuum leaks in the intake system
Symptoms of P0108 2016 Chevrolet Silverado
- Decreased fuel efficiency
- Rough idling or engine misfires
- Engine hesitation or lack of power
- Engine stalling
- Check Engine Light illuminated
How to Fix P0108 2016 Chevrolet Silverado
- Diagnose the issue by using a scan tool to read the DTC and checking the MAP/BARO sensor readings.
- Inspect the wiring harness for any damage or corrosion, repairing or replacing as necessary.
- Test the MAP and BARO sensors using a multimeter to ensure they are functioning within specifications, replacing if faulty.
- Clear the DTC and reset the ECM to see if the code returns, indicating a successful repair.
- Test drive the vehicle to ensure proper engine performance and verify that the code does not reappear.
