Code C128D GMC Description
The C128D GMC code indicates an ABS Boost Pressure Sensor Raw Offset Error. This means that there is an issue with the boost pressure sensor in the vehicle's anti-lock braking system (ABS). The boost pressure sensor is responsible for monitoring the pressure in the brake system and providing feedback to the ABS control module. When the sensor detects an error in the raw offset, it means that the sensor is not providing accurate data, which can lead to problems with the ABS functionality.
