Solution

1. Preparation

Ensure the vehicle is parked on a flat surface with the engine off.
Gather all necessary tools and parts.

2. Check Power Steering Fluid

Tools Required:
- Fluid pump (if needed)
Locate the power steering fluid reservoir.
Check the fluid level; add the recommended power steering fluid if low.
Inspect fluid for contamination; if contaminated, drain and replace with new fluid.

3. Inspect Power Steering Pump

Tools Required:
- Wrench set
- Torque wrench
Remove the drive belt from the power steering pump.
Inspect the pump for leaks or damage; replace if necessary.
Reinstall the drive belt and ensure it is properly tensioned to manufacturer's specifications.

4. Test Electric Power Steering Motor

Tools Required:
- Multimeter
Disconnect the EPS motor connector.
Use a multimeter to check for voltage at the EPS motor terminals while the ignition is on.
If no voltage is present, trace wiring for shorts or breaks and repair as needed.
If voltage is present but the motor does not operate, replace the EPS motor.

5. Check Steering Angle Sensor

Tools Required:
- OBD-II scanner
Use the scanner to access the steering angle sensor data.
Check for sensor calibration; perform a calibration procedure if necessary following the vehicle's service manual.
Replace the sensor if it is faulty.
