Solution

1. Preparation

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

2. Remove the Steering Angle Sensor

Locate the steering angle sensor, typically mounted on the steering column.
Use a socket set to remove the mounting screws.
Carefully disconnect the electrical connector from the sensor.
Remove the sensor from its mounting position.

3. Inspect and Clean

Inspect the sensor for physical damage or wear.
Clean the sensor and its connectors with electrical contact cleaner to remove any dirt or corrosion.

4. Replace the Sensor (if necessary)

If the sensor is found to be faulty, replace it with a new one.
Position the new sensor onto the mounting bracket and secure it using the mounting screws.
Reconnect the electrical connector to the new sensor.

5. Calibration

Reconnect the negative battery terminal.
Use a steering angle sensor calibration tool to calibrate the new sensor according to the manufacturer's specifications.
Follow the prompts on the calibration tool to ensure accurate calibration.

6. Final Assembly

Reinstall any components removed during the repair.
Ensure all connections are secure and that no tools are left in the engine compartment.
