Code C0545 Description

The Power Steering Control Module continuously monitors the Steering Wheel Torque Sensor. As the steering wheel is turned and torsional twist is applied to the steering shaft the signal is processed by the Power Steering Control Module to calculate the steering torque. The Diagnostic Trouble Code (DTC) will be set when the Power Steering Control Module detects a short to ground, short to voltage, or an open/high resistance on any of the torque sensor circuits.
