Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool before starting.

2. Inspect and Repair Power Steering System

Check Fluid Levels:
- Remove the power steering fluid reservoir cap.
- Inspect the fluid level; if low, top off with manufacturer-recommended fluid.
Identify Leaks:
- Visually inspect power steering lines, hoses, and connections for signs of leakage.
- Replace any damaged hoses or seals.

3. Test and Replace Power Steering Pump

Pump Operation:
- With the engine running, observe the power steering pump for any unusual noises or vibrations.
- If the pump is faulty, proceed with replacement.
Remove the Power Steering Pump:
- Disconnect the fluid lines using a wrench.
- Remove the mounting bolts securing the pump to the engine.
- Take out the old pump and prepare to install the new one.
Install New Power Steering Pump:
- Position the new pump and secure it with mounting bolts to the engine (torque to manufacturer specifications).
- Reconnect the fluid lines and ensure they are tight to prevent leaks.

4. Steering Angle Sensor Adjustment (if applicable)

Access Steering Angle Sensor:
- Remove the steering wheel cover and airbag (follow safety procedures for airbag handling).
- Locate the steering angle sensor.
Calibrate:
- Using a scan tool, initiate the calibration procedure for the sensor according to manufacturer specifications.
- Reassemble components after calibration.
