Code C1168 Description

The C1168 code refers to a fault in the Right Rear ABS Wheel Speed Sensor or its sensor rotor. The ABS system in a vehicle is crucial for safety, as it helps prevent the wheels from locking up during hard braking, allowing the driver to maintain control of the vehicle. The wheel speed sensors monitor the speed of each wheel and send this information to the ABS control module. If the sensor detects a difference in speed between wheels, the ABS system will adjust the braking force to prevent skidding.
