Locate the power steering pump and check for any signs of damage or wear.
Listen for unusual noises while the engine is running, indicating pump failure.
If the pump is faulty, replace it by removing the pump and installing a new one, ensuring proper alignment.

5. Test Electrical Connections

Locate the power steering control module and check all electrical connectors for corrosion or loose connections.
Use a multimeter to test for continuity in the wires leading to the module.
Repair or replace any damaged wiring.

6. Steering Angle Sensor Check
