Code C1465 Description

The C1465 code indicates a problem with the front speed sensor on the left side of the vehicle. The speed sensor is a crucial component of the vehicle's anti-lock braking system (ABS) and traction control system. The sensor measures the speed of the wheel and sends this information to the vehicle's electronic control module (ECM). This data is used to ensure that the wheels are rotating at the same speed and to prevent skidding during braking or acceleration.
