Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, steering wheel puller, torque wrench
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the vehicle to cool before working on any components.

2. Address Power Steering Fluid

Sub-steps:
1. Locate the power steering reservoir under the hood.
2. Remove the cap and check the fluid level; if low, top off with the manufacturer-recommended power steering fluid.
3. Inspect the fluid for contamination; if dirty or burnt, consider flushing the system.

3. Inspect and Repair Steering Column

Sub-steps:
1. Remove the necessary panels to access the steering column.
2. Check for any signs of wear or damage on the steering column and linkage.
3. If necessary, replace any damaged components or tighten loose bolts to ensure proper alignment.

4. Replace Steering Position Sensor

Sub-steps:
1. Disconnect the battery and locate the steering position sensor.
2. Remove the old sensor using a socket set and replace it with a new one.
3. Reconnect the battery and clear any stored error codes from the system.

5. Test Drive and Final Inspection

Sub-steps:
1. Start the vehicle and turn the steering wheel to ensure proper operation.
2. Conduct a test drive to verify that the steering functions normally without locking up.
3. Recheck the power steering fluid level and top off if necessary.
