The P1108 fault code refers to a malfunction in the Dual Alternator Battery Lamp Circuit.

This code is stored when the Engine Control Module (ECM) detects that the output voltage from the Barometric Pressure (BARO) sensor is equal to or exceeds a specified value.

The BARO sensor is responsible for monitoring atmospheric pressure and helps the ECM estimate the appropriate intake airflow.

When this sensor malfunctions, it can lead to issues with the dual alternator battery lamp circuit. It is important to address this fault code promptly to ensure proper functioning of the vehicle’s electrical system.
