Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent any electrical shorts.

2. Inspect Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add manufacturer-recommended fluid if low.
If the fluid is dark or contaminated, drain and replace it.

3. Check Power Steering Pump

Remove any components obstructing access to the power steering pump.
Inspect the pump for leaks or damage; replace if necessary.
If the pump is functioning but making noise, consider replacing it.

4. Test and Repair Electrical Connections

Inspect wiring harnesses and connectors associated with the power steering system.
Clean or replace any corroded connectors.
Use a multimeter to check voltage at the power steering motor, ensuring it's within specifications.

5. Replace Steering Angle Sensor (if necessary)

If diagnosed as faulty, locate the steering angle sensor on the steering column.
Disconnect the electrical connector and remove any mounting screws.
Install the new steering angle sensor and reconnect the electrical connector.
