Solution

1. Preparation

Gather necessary tools and safety equipment.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Power Steering Fluid

Remove the power steering reservoir cap.
Use a turkey baster to extract old fluid if it's contaminated.
Refill with manufacturer-recommended power steering fluid to the proper level.
Check for any visible leaks or damage to the reservoir.

3. Check and Replace Power Steering Pump (if necessary)

Remove the serpentine belt from the power steering pump pulley using a socket set.
Disconnect the power steering lines from the pump, ensuring to catch any fluid in a container.
Remove the mounting bolts using a socket set and carefully take out the pump.
Install the new power steering pump in reverse order, ensuring all connections are tight and without leaks.
Reinstall the serpentine belt, ensuring proper tension.

4. Adjust Steering Angle Sensor

Locate the steering angle sensor, typically near the steering column.
Disconnect the electrical connector and remove the sensor from its housing.
Reinstall the new sensor and connect the electrical harness.
Use a scan tool to recalibrate the steering angle sensor as per manufacturer specifications.

5. Reconnect Battery and Test Drive

Reconnect the battery terminals.
Start the vehicle and check for any warning lights.
Test drive the vehicle, monitoring steering responsiveness and checking for unusual noises or warning messages.
