Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the engine is off.
Disconnect the battery to avoid any electrical shorts.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; top off with manufacturer-recommended fluid if low.
Inspect the fluid for contamination; if dirty, flush the system.

3. Inspect Power Steering Pump

Locate the power steering pump.
Check for leaks around the pump and hoses.
If leaks are found, replace the power steering pump and any damaged hoses.

4. Test Power Steering Motor

Reconnect the battery.
Use a multimeter to check voltage at the power steering motor connector while turning the steering wheel.
If voltage is absent or inconsistent, replace the power steering motor.

5. Replace Steering Angle Sensor (if necessary)

If diagnostics point to a faulty steering angle sensor, locate the sensor on the steering column.
Disconnect the wiring harness and remove the sensor.
Install the new sensor and reconnect the wiring harness.
