Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to ensure safety.

2. Power Steering Fluid Check

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the dipstick.
If low, top off with the manufacturer-recommended power steering fluid.

3. Inspect and Replace EPS Motor

Remove any covers obstructing access to the EPS motor.
Disconnect the electrical connector from the EPS motor.
Unbolt the EPS motor from its mounting position using the socket set.
Install the new EPS motor by reversing the removal steps.
Reconnect the electrical connector and secure all fasteners to the specified torque.

4. Steering Angle Sensor Calibration

Reconnect the negative battery terminal and start the vehicle.
Use an OBD-II scanner to access the steering angle sensor settings.
Follow the scanner prompts to calibrate the steering angle sensor as necessary.

5. Final Inspection

Check for any leaks around the power steering system.
Test drive the vehicle to ensure the EPS light does not reappear and that steering is responsive.
