Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent any electrical issues during repair.

2. Inspect and Replace Power Steering Fluid

Remove the power steering fluid reservoir cap.
Use a turkey baster to remove old fluid and replace it with the manufacturer-recommended fluid.
Check for any contaminants in the fluid. If dirty, consider a complete fluid flush.

3. Replace Power Steering Pump (if needed)

Tools Required: Socket set, wrench set, fluid catch pan.
Remove the drive belt by loosening the tensioner.
Disconnect the power steering lines from the pump, using a fluid catch pan to collect any spilled fluid.
Remove the mounting bolts from the power steering pump and detach it from the engine.
Install the new pump by reversing the removal steps, ensuring all connections are secure.

4. Inspect and Repair Electrical Connections

Reconnect any loose or corroded electrical connectors to the power steering assist module and motor.
Use a multimeter to test continuity and voltage at the connectors; repair or replace as necessary.

5. Steering Angle Sensor Calibration

After reassembly, turn the ignition on without starting the engine.
Use a scan tool to recalibrate the steering angle sensor according to manufacturer specifications.
Start the engine and turn the steering wheel from lock to lock to ensure proper calibration.
