Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shock.
Allow the engine to cool before starting work.

2. Inspect Power Steering Fluid

Sub-steps:
- Locate the power steering fluid reservoir.
- Remove the cap and check the fluid level; add the appropriate type of power steering fluid if low (typically Honda Power Steering Fluid).
- Inspect the fluid for contamination; if dirty, it needs to be replaced.

3. Replace Power Steering Pump (if faulty)

Sub-steps:
- Remove any components obstructing access to the power steering pump (e.g., intake hose, serpentine belt).
- Disconnect the power steering lines from the pump using a flare nut wrench.
- Unbolt the power steering pump from its mounting bracket and remove it.
- Install the new power steering pump and torque bolts to manufacturer specifications (typically around 15-20 ft-lbs).
- Reconnect the power steering lines and ensure there are no leaks.

4. Inspect and Fix Electrical Connections

Sub-steps:
- Locate the power steering control module and inspect the connectors.
- Clean any corrosion with electrical cleaner and a brush.
- Ensure all connections are secure and free from damage.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the vehicle and check for the check engine light; verify normal steering operation.
