Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, power steering fluid.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect and Replace Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check fluid level; if low, add manufacturer-recommended power steering fluid.
If fluid is dirty or contaminated, proceed to drain and replace.
- Locate the drain plug or disconnect the return line from the power steering pump.
- Allow old fluid to drain completely into a suitable container.
- Reconnect lines and refill with new power steering fluid to the appropriate level.

3. Inspect Power Steering Pump

Visually inspect the power steering pump for any signs of leaks or damage.
If necessary, remove the power steering pump:
- Disconnect the fluid lines (use a line wrench to avoid damage).
- Unbolt the pump from its mounting bracket.
Replace the pump if it shows signs of failure (e.g., noise, fluid leaks).

4. Check Steering Angle Sensor

Locate the steering angle sensor, typically found on the steering column.
Disconnect the sensor connector.
Use a multimeter to test the sensor's resistance and ensure it meets specifications (refer to the service manual for exact values).
Replace the sensor if it is faulty.

5. Reassemble and Test

Reconnect all components, ensuring proper torque specifications for bolts.
Reconnect the battery and check the power steering system for any leaks.
Start the engine and turn the steering wheel from lock to lock to bleed any air from the system.
