Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety glasses and gloves for protection.

2. Check and Refill Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check the fluid level; it should be between the "Min" and "Max" marks.
3. If low, add the recommended power steering fluid (Honda Genuine Power Steering Fluid).
4. Replace the cap securely.

Tools Required: None for this step.

3. Inspect and Repair Leaks

Sub-steps:
1. Visually inspect power steering hoses and connections for cracks or leaks.
2. Tighten any loose connections or replace damaged hoses.
3. If the pump is leaking, remove the power steering pump using the following steps:
  - Disconnect the battery.
  - Remove the drive belt from the pump.
  - Disconnect the fluid lines from the pump.
  - Unbolt the pump from its mounting bracket and remove it.
  - Install a new pump if necessary.

Tools Required: Socket set, wrench set, fluid catch pan.

4. Replace Power Steering Pump (if necessary)

Sub-steps:
1. Install the new power steering pump in reverse order of removal.
2. Torque the mounting bolts to the manufacturer's specifications (typically around 18-25 ft-lbs).
3. Reconnect the fluid lines and ensure all connections are tight.
4. Reinstall the drive belt, ensuring proper tension.

Tools Required: Torque wrench.

5. Bleed the Power Steering System

Sub-steps:
1. Fill the power steering reservoir to the "Max" line with fluid.
2. Start the engine and turn the steering wheel from lock to lock several times to expel air.
3. Check fluid level again and top off as necessary.

Tools Required: Funnel.
