Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, steering angle sensor calibration tool.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect and Repair Wiring

Remove the steering column cover to access the wiring and connectors.
Check for frayed wires, loose connections, or corrosion at the steering angle sensor connector.
Repair or replace any damaged wiring or connectors as necessary.

3. Replace Steering Angle Sensor

Tools Required: Socket set, torque wrench.
Remove the steering wheel (using a steering wheel puller if necessary) to access the steering angle sensor.
Disconnect the old steering angle sensor by unplugging it from the harness.
Install the new steering angle sensor by connecting the harness and securing it in place.
Reinstall the steering wheel, ensuring it is aligned correctly. Use a torque wrench to tighten to the manufacturer's specifications.

4. Calibration of Steering Angle Sensor

Reconnect the vehicle battery.
Use a diagnostic tool to perform a steering angle sensor calibration.
Follow the tool's prompts to ensure proper calibration.

5. Final Inspection

Confirm that all connections are secure and that no tools are left in the engine bay.
Test drive the vehicle to ensure steering responsiveness and that warning lights are no longer illuminated.
