Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is on a flat surface and the ignition is off.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Inspect and Replace the Fuse

Locate the fuse box, typically under the dashboard or in the engine bay.
Remove the cover and find the power steering fuse (refer to the owner’s manual for exact location).
Check the fuse for continuity using a multimeter. If blown, replace it with a new fuse of the same amperage.
Reinstall the fuse box cover and reconnect the negative battery terminal.

3. Check Power Steering Motor and Wiring

Remove any panels obstructing access to the power steering motor.
Inspect the motor for any signs of wear or damage.
Check the wiring harness for loose connections or frayed wires.
If damaged, repair or replace the wiring as necessary.

4. Test and Replace Steering Angle Sensor

Locate the steering angle sensor, typically found on the steering column.
Use a multimeter to check the sensor's resistance and voltage output while turning the steering wheel.
If the sensor is malfunctioning, replace it according to manufacturer specifications.

5. Reconnect Battery and Test System

Reconnect the negative battery terminal.
Start the vehicle and check for any warning lights on the dashboard.
Test the steering assist by turning the wheel at low and high speeds.
