Solution

1. Preparation

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

2. Inspect and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the "MIN" and "MAX" marks.
If low, refill with the manufacturer-recommended power steering fluid.
Start the engine and turn the steering wheel from side to side to circulate fluid.

3. Replace Power Steering Pump (if necessary)

Tools Required: Socket set, torque wrench, fluid catch pan, power steering fluid.
Steps:
1. Remove the drive belt from the power steering pump pulley.
2. Disconnect the power steering fluid lines from the pump (use a catch pan to collect any fluid).
3. Unbolt the power steering pump from its mounting bracket.
4. Install the new power steering pump, tightening to the manufacturer’s torque specifications.
5. Reconnect the fluid lines and replace the drive belt.

4. Replace Steering Angle Sensor (if necessary)

Tools Required: Socket set, multimeter.
Steps:
1. Remove the airbag and steering wheel to access the steering column.
2. Disconnect the wiring harness from the steering angle sensor.
3. Unscrew the old sensor and remove it from the column.
4. Install the new steering angle sensor and reconnect the wiring harness.
5. Reassemble the steering wheel and airbag, ensuring all connections are secure.

5. Calibrate Steering Angle Sensor

Use a diagnostic tool to perform the calibration process according to the vehicle's service manual. Follow the prompts on the tool to complete the calibration.
