Solution

1. Preparation

Gather Tools: OBD-II scanner, multimeter, socket set, torque wrench, steering wheel puller (if necessary).
Safety Precautions: Disconnect the battery before working on electrical systems. Allow the vehicle to cool before inspection.

2. Address Steering Angle Sensor

Remove Steering Wheel:
- Use a steering wheel puller to carefully detach the steering wheel.
- Disconnect the airbag connector (ensure battery is disconnected).
Replace or Calibrate Sensor:
- If faulty, replace the steering angle sensor with a new unit.
- If calibration is needed, use an OBD-II scanner to recalibrate the sensor.

3. Inspect and Replace Power Steering Components

Check Power Steering Fluid:
- If fluid is low, top off with the recommended type (usually ATF or specific power steering fluid).
Inspect Power Steering Pump:
- If noise or signs of failure are present, replace the power steering pump.

4. Wheel Alignment Adjustment

Perform Wheel Alignment:
- Take the vehicle to a certified alignment shop to correct any misalignment.
- Ensure all alignment settings meet manufacturer specifications.
