Code C0245 Buick Description

The C0245 Buick code indicates a Wheel Speed Sensor Frequency Malfunction. This means that the vehicle's onboard computer has detected an issue with the wheel speed sensor's signal frequency, which is crucial for the proper functioning of the vehicle's anti-lock braking system (ABS) and traction control system (TCS). The wheel speed sensors are responsible for monitoring the rotational speed of each wheel and sending this data to the ABS and TCS systems to help prevent wheel lock-up during braking and improve traction control.
