Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add the appropriate power steering fluid (refer to the owner's manual for specifications) if low.
Inspect the fluid for contamination; replace if necessary.

3. Inspect and Replace Hoses

Visually inspect all power steering hoses for signs of wear or leaks.
If a hose is damaged, use a socket set to remove the old hose and replace it with a new one, ensuring proper routing and secure connections.
Torque connections to manufacturer's specifications.

4. Test Electric Power Steering Motor

Reconnect the battery and use a multimeter to check the EPS motor voltage while turning the steering wheel.
If voltage is outside the normal range, replace the EPS motor.
Remove the motor using a socket set, disconnect wiring harness, and install the new motor ensuring it is properly calibrated.

5. Calibrate Steering Angle Sensor

After any repairs, use a scan tool to perform a steering angle sensor calibration if applicable.
Follow the specific calibration procedure as outlined in the service manual.
