Code P1108 Chevrolet Description
The P1108 diagnostic trouble code in Chevrolet vehicles indicates a problem with the comparison between the Barometric (BARO) pressure sensor and the Manifold Absolute Pressure (MAP) sensor. The BARO sensor measures the ambient air pressure outside of the engine, while the MAP sensor measures the pressure inside the intake manifold. These two sensors work together to ensure the engine is receiving the correct amount of air for optimal performance and fuel efficiency. When the comparison between these two sensors is too high, it means that there is an inconsistency in the pressure readings, which can lead to various issues with the engine's performance.
