Solution

1. Preparation

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

2. Inspect and Replace Fuse

Locate the power steering fuse in the fuse box.
Remove the fuse using a fuse puller.
Inspect the fuse for any signs of damage; replace it with one of the same amperage if necessary.

3. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Check the fluid level; if low, add the manufacturer-recommended power steering fluid.
Recheck the fluid level after a few turns of the steering wheel to ensure proper fill.

4. Inspect Power Steering Motor

Remove the cover to access the power steering motor.
Visually inspect the motor for any physical damage or signs of wear.
Clean any corrosion from the electrical connectors using a contact cleaner.

5. Test Voltage at Power Steering Motor

Reconnect the battery terminal.
Use a multimeter to check the voltage at the power steering motor while the steering wheel is being turned.
Ensure that the voltage reading meets the specifications outlined in the service manual.

6. Recalibrate Steering Angle Sensor (if needed)

Use a scan tool to access the steering angle sensor settings.
Follow the manufacturer's procedure to recalibrate the sensor, ensuring it reads correctly for optimal power steering function.
