Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, fluid pump (if necessary)
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering reservoir.
2. Remove the cap and check the fluid level; if low, use a clean funnel to add the recommended power steering fluid specified in the owner’s manual.
3. If the fluid is dirty or contaminated, drain the reservoir and replace it with fresh fluid.

3. Check and Replace Steering Angle Sensor

Sub-steps:
1. Locate the steering angle sensor, typically mounted on the steering column.
2. Disconnect the electrical connector from the sensor.
3. Remove the sensor using appropriate socket sizes, ensuring to remember the torque specifications for reinstallation.
4. Install the new steering angle sensor and reconnect the electrical connector.
5. Torque the sensor to the manufacturer's specifications.

4. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any trouble codes from the vehicle's computer.
Start the engine and allow the vehicle to idle for a few minutes.

5. Test Steering Functionality

With the vehicle running, turn the steering wheel fully left and right to check for power assist.
Test drive the vehicle to ensure that steering assistance is fully restored.
