Code C0105 Description

The C0105 diagnostic trouble code (DTC) indicates an abnormal signal from the rear ABS wheel speed sensor on the right side of the vehicle. The ABS (Anti-lock Braking System) is a crucial safety feature in modern vehicles that prevents wheel lock-up during braking, helping the driver maintain control of the vehicle in emergency situations. The wheel speed sensors monitor the rotational speed of each wheel and send this data to the ABS control module. When the ABS control module detects an abnormal signal from the rear ABS wheel speed sensor on the right side, it triggers the C0105 DTC.
