If you own a Ford Fusion, you may have heard of the term Electronic Power Steering (EPS). This system is responsible for providing power assistance to the steering wheel, making it easier for you to turn the wheel and control the direction of your vehicle. In this section, we will discuss the working principle of EPS in the Ford Fusion and how it helps to prevent power steering assist faults.

EPS in the Ford Fusion works by using an electric motor to assist the steering system. The motor is controlled by a module that interprets the driver’s input and regulates the motor’s operation. When you turn the steering wheel, the module senses the direction and force of your input and sends a signal to the motor to provide the appropriate amount of assistance.

One of the benefits of EPS is that it can reduce the amount of effort required to turn the steering wheel, especially at low speeds. This can be particularly helpful when maneuvering in tight spaces or parking. Additionally, EPS can improve the overall handling and stability of your vehicle, especially when driving at higher speeds.

However, like any other system in your vehicle, EPS can experience faults or malfunctions. In the case of power steering assist faults on the Ford Fusion, there are several possible causes, including blown fuses, faulty power steering pumps, and worn-out electrical wires.

To prevent power steering assist faults, it is important to regularly check the fuse box and confirm that none of the fuses related to power steering are missing or blown. If you notice any blown fuses, replace them immediately and monitor the system. If it blows a fuse again, you need to have the electrical system troubleshot. Additionally, if your Ford Fusion is part of a recall, confirm if it was taken for a fix.

Why Does My Ford Fusion Display “Power Steering Assist Fault”?

If your Ford Fusion has been displaying a “power steering assist fault” message, it is likely that there is a problem with the power steering system. There are several potential causes for this issue, including sensor issues, system malfunctions, and other potential causes.

Sensor Issues

One common culprit behind a disabled power steering system is a malfunctioning sensor. The steering wheel position sensor (SWPS) and torque sensor are two sensors that can cause issues with the system.

A faulty SWPS can send inaccurate data about the steering wheel’s position to the control module, disrupting the system’s ability to provide appropriate assistance. Similarly, a malfunctioning torque sensor can lead to the system misinterpreting driver input and hindering assistance.

System Malfunctions

Another potential cause of a power steering assist fault is a malfunction within the EPS system itself. Software bugs, control module failure, and electrical wiring problems are all possible system malfunctions that can cause issues with the power steering system.

Temporary glitches in the EPS software can disrupt communication between sensors and the control module, while internal hardware issues within the module can lead to a complete system malfunction. Faulty wiring or damaged connectors can also disrupt communication within the EPS system.

Other Potential Causes

In some rare instances, a failing battery can cause insufficient voltage to the EPS system, triggering a warning. Loose steering connections, such as worn or loose components in the steering linkage, can also increase steering effort and mimic a power steering issue.

What to Do When You See ‘Power Steering Assist Fault’

If you are driving your Ford Fusion and see the message “Power Steering Assist Fault” on your dashboard, it is important to take immediate action to ensure your safety and prevent further damage to your vehicle. Here are the steps you should take:

Pull Over Safely: This message indicates a critical safety concern. Immediately pull over to a safe location and turn off the engine. This will prevent any further damage to your vehicle and ensure your safety.
Check Power Steering Fluid: If your power steering fluid is low, it could be the cause of the problem. Check the level and add more fluid if necessary.
Restart the Engine: After checking the power steering fluid, restart the engine. If the message disappears, the issue may have been low power steering fluid. However, if the message remains, there may be a more serious issue.
Limited Steering Capability: Be prepared for increased steering effort. Maneuvering will require more muscle, but steering functionality should not be completely lost.
Visit a Mechanic: If the message remains after checking the power steering fluid and restarting the engine, it is recommended to visit a mechanic as soon as possible. They will be able to diagnose the issue and provide a solution to fix the problem.

It is important to address the issue as soon as possible to prevent further damage to your vehicle and ensure your safety on the road. By following these steps, you can address the “Power Steering Assist Fault” message and get back to driving safely.
