Code C0225 Description

The C0225 diagnostic trouble code (DTC) specifically indicates that there is an issue with the left front speed sensor or its circuit being open. The speed sensor is a crucial component in the vehicle's anti-lock braking system (ABS) and traction control system. It is responsible for measuring the speed of the left front wheel and transmitting this information to the vehicle's electronic control module (ECM) for proper operation of the ABS and traction control systems.
