The 2012 Ford Fusion is known for its reliability, but many owners encounter the Power Steering Assist Fault message, which can make steering difficult. This guide aims to provide solutions for both DIY enthusiasts and those seeking professional help.

Understanding the Power Steering Assist Fault

The Power Steering Assist Fault message indicates issues with the electric power steering system. This system uses an electric motor to assist with steering, making it easier to turn the wheel, especially at low speeds. When the fault occurs, drivers may experience increased difficulty in steering, similar to vehicles without power assist.

Common causes of this fault include:

  • Electrical issues: Blown fuses, damaged wiring harnesses, or loose connectors.
  • Sensor malfunctions: Problems with wheel speed sensors or steering angle sensors.
  • Mechanical faults: Issues with the steering motor or internal steering components.

Diagnosing the Problem

Before attempting repairs, it's essential to diagnose the issue accurately. Here are some steps to follow:

1. Check for Diagnostic Trouble Codes (DTCs): Use an OBD-II scanner to retrieve any stored codes. Common codes related to power steering issues include C1277 and U3000.

2. Inspect Fuses: Check fuse #F19 in the under-hood fuse box, as a blown fuse can cause power steering failure.

3. Examine Wiring and Connectors: Look for any damaged wiring or loose connectors around the steering column and rack.

4. Test Sensors: Ensure that wheel speed and steering angle sensors are functioning properly.

DIY Repair Steps

If you're comfortable with basic automotive repairs, you can attempt some fixes yourself:

  • Replacing a Blown Fuse:

- Locate the under-hood fuse box on the driver’s side.

- Find and replace fuse #F19 (25A) if it is blown.

  • Inspecting and Reseating Connectors:

- Check connectors along the steering column and rack for looseness.

- Reseat any loose connectors securely.

  • Cleaning Sensors:

- Inspect wheel speed sensors for debris and clean them if necessary.

If these steps do not resolve the issue, further diagnosis may be required, potentially involving professional assistance.

Professional Repair Considerations

For more complex issues such as mechanical failures or persistent electrical problems, it may be necessary to consult a professional mechanic. Repairs could include:

  • Replacing faulty sensors or wiring harnesses.
  • Addressing issues with the electric power steering motor or rack assembly.

Be aware that repairs can be costly, often exceeding $1,700 depending on the extent of damage.
