Code C0545:4B Description
The C0545:4B diagnostic trouble code indicates that the steering wheel torque sensor calibration has not been learned by the vehicle's system. The torque sensor is responsible for detecting the driver's input on the steering wheel and providing this information to the vehicle's electronic control unit (ECU). When the calibration is not learned, it can lead to inaccurate readings and affect the vehicle's stability control system, traction control system, and other safety features that rely on the steering input data. This issue can result in poor handling, reduced steering response, and potentially compromise the vehicle's overall safety.
Common Causes of C0545:4B
- Faulty torque sensor
- Loose or damaged wiring connections
- Steering angle sensor calibration not performed correctly
- Software issues in the vehicle's ECU
- Electrical system malfunction
Symptoms of C0545:4B
- Increased steering effort required
- Steering wheel feels loose or unresponsive
- Traction control or stability control warning lights illuminated on the dashboard
- Vehicle veering to one side while driving
- Vehicle stability control system malfunction
How to Fix C0545:4B
- Perform steering wheel torque sensor calibration using a diagnostic scan tool
