Visually inspect the wiring harness connected to the power steering motor.
Disconnect the harness and check for corrosion or damage.
Clean connections and reconnect securely.

4. Test Power Steering Motor

Using a multimeter, check voltage at the power steering motor while the vehicle is turned on.
If the voltage is outside of manufacturer specifications, replace the power steering motor.

5. Replace Steering Angle Sensor (if faulty)

Locate the steering angle sensor, often found near the steering column.
Disconnect the wiring harness and remove the mounting bolts.
