Solution

1. Preparation

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

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, top off with the recommended power steering fluid (refer to the owner’s manual for specifications).

3. Inspect Power Steering Pump

Reconnect the battery.
Start the engine and let it idle.
Listen for unusual noises from the power steering pump while turning the steering wheel.
If noise persists, consider replacing the power steering pump.

4. Inspect Electrical Connections

Locate the connectors to the power steering pump and steering angle sensor.
Ensure all connections are secure and free of corrosion.
Clean any corroded contacts and apply dielectric grease.

5. Replace Faulty Components

If any issues are found during inspections (e.g., defective pump, damaged sensors), replace the faulty components.
Follow manufacturer specifications for torque and installation procedures.

6. Final Assembly

Reassemble any components removed during inspection.
Ensure all bolts and connections are tightened to specifications.
Reconnect the battery.
