Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the steering wheel in the straight-ahead position.

2. Inspect and Clean

Sub-steps:
1. Disconnect the negative battery terminal to avoid electrical shorts.
2. Remove the lower steering column cover using a socket set.
3. Visually inspect the steering angle sensor and its wiring for any visible damage.
4. Clean any corrosion from connectors using electrical contact cleaner.

3. Replace Steering Angle Sensor

Sub-steps:
1. Disconnect the wiring harness from the steering angle sensor.
2. Remove the mounting screws securing the sensor to the steering column.
3. Install the new steering angle sensor by reversing the removal steps.
4. Torque the mounting screws to manufacturer specifications (usually around 10-12 Nm).

4. Recalibration

Sub-steps:
1. Reconnect the negative battery terminal.
2. Use an OBD-II scanner to perform the steering angle sensor recalibration.
3. Follow the on-screen instructions until calibration is complete.
