Experiencing a power steering assist fault in your Ford Fusion can be alarming and potentially dangerous. This issue typically manifests as difficulty steering, which can compromise your safety on the road. Understanding the causes and solutions is essential for maintaining your vehicle's performance.

Common Causes of Power Steering Assist Fault

The power steering assist fault can arise from several issues, including:

  • Low power steering fluid levels: Insufficient fluid can lead to inadequate pressure in the system.
  • Faulty power steering pump: A malfunctioning pump may not provide the necessary assistance.
  • Worn-out power steering belt: A damaged or loose belt can impede the pump's operation.
  • Electrical issues: Problems with wiring or sensors can disrupt the system's functionality.
  • System malfunctions: Issues with the power steering control module (PSCM) may also trigger faults.

Recognizing these causes can help you address the problem effectively.

Steps to Fix Power Steering Assist Fault

If you encounter a power steering assist fault, follow these steps to troubleshoot and potentially resolve the issue:

Step 1: Check Power Steering Fluid

Inspect the power steering fluid level in your reservoir. Ensure it is at the recommended level, and check for any signs of contamination. If low, refill with the appropriate fluid type as specified in your owner's manual.

Step 2: Inspect for Leaks

Look for any visible leaks around the power steering system. Leaks can lead to fluid loss and should be addressed immediately. If you find any leaks, consider replacing damaged hoses or seals.

Step 3: Examine Belts and Pulleys

Check the condition of the power steering belt and pulleys. Look for signs of wear, fraying, or looseness. If any components are damaged, replace them to ensure proper operation.

Step 4: Reset the System

Sometimes, a simple reset can resolve minor electronic glitches. To do this:

1. Turn off the engine and remove the key from the ignition.

2. Wait for at least one minute.

3. Restart the vehicle and check if the fault persists.

Step 5: Consult a Professional

If none of these steps resolves the issue, it's advisable to consult a qualified mechanic. They can perform a thorough diagnostic to identify underlying problems such as faulty sensors or electrical issues that may require specialized tools and expertise.

To prevent future power steering assist faults, consider implementing regular maintenance practices:

  • Regularly check fluid levels and top off as needed.
