Code C0545 Description

The C0545 code indicates a malfunction in the steering wheel torque sensor, which is a crucial component in modern vehicles equipped with electronic power steering systems. The torque sensor measures the amount of force applied to the steering wheel by the driver and sends this information to the vehicle's electronic control unit (ECU). This data is used to assist in providing the appropriate level of power steering assistance, enhancing the driver's control over the vehicle.
