A Power steering assist fault in a Ford Fusion is a common issue that can occur in various car models. This fault occurs when the power steering system of the vehicle fails to function properly, which can make steering more difficult and dangerous.
In this blog post, we will be discussing this common issue faced by Ford Fusion owners. We’ll explore the causes, its symptoms, and the steps that you can take to fix it.
How Does a Power Steering Work?
This is a system that helps to make steering easier by reducing the effort required to turn the steering wheel. It is an automotive system that uses a separate motor or engine power to reduce the effort necessary to turn the front wheels. This system helps drivers steer the car and makes it easier to maneuver at lower speeds.
To perform better, the power steering uses hydraulic pressure, which is generated by the power steering pump and controlled by the unit control module.
What Are the Causes of Power Steering Assist Failure?
1. Low Steering Fluid Level
The power steering system relies on hydraulic pressure to assist with steering. The small force applied on the steering wheel is amplified and transmitted through the fluid to help turn our car in the desired direction.
If the fluid level is low, there may not be enough pressure to operate the system effectively. This can cause the steering to become difficult or unresponsive. Therefore, it is essential to check the fluid level regularly and add more if needed.
2. Faulty Power Steering Pump
The power steering pump is responsible for generating the hydraulic pressure needed to assist with steering.
If the pump is faulty, it may not be able to generate enough pressure to operate the power steering system properly. This can cause the steering to become difficult or unresponsive. If you suspect a faulty pump, it is essential to have it replaced as soon as possible.
3. Electrical Issues
Many modern vehicles have an electronically controlled power steering system. Electrical issues such as a blown fuse, a faulty relay, or a damaged wire can cause the power steering system to fail.
These issues can prevent the power steering control module from receiving the signals it needs to operate the system effectively.
4. Faulty Power Steering Control Module
The power steering control module is responsible for regulating the power steering system. It is the interface between the steering wheel and the steering column necessary to transfer the driver’s input rotation.
It integrates clock springs, steering angle sensors, power tilt/telescope column controls, pedal position controls, and other simple and complex switches. When it is damaged, it can cause the power steering system to fail.
Signs of a Faulty Control Module
- Difficulty turning the steering wheel
- Warning lights on the dashboard
- Whining Noise When You Turn the Wheel
- Squealing Noise Upon Starting Your Vehicle
Steering Gear Issues
The steering gear is responsible for changing the movement of the steering wheel into the movement of the wheels. If the gear is damaged or worn, it can cause the power steering system in your ford to develop a fault.
Signs of Gear Issues
- A loose or wobbly steering wheel
- Unusual noises when turning
- Difficulty steering
How to Fix Power Steering Assist Fault in a Ford Fusion
The power steering assist fault in a Ford Fusion can result from various reasons, including a faulty steering gear, a failed power steering pump, or a malfunctioning power steering control module. Here are some steps that you can take to fix the power steering assist fault in a Ford Fusion:
1. Check the Power Steering Fluid Level
Start by checking the power steering fluid level. A low fluid level can cause the power steering assist fault. If the fluid level is low, add more fluid to the recommended level.
2. Check the Battery
A weak or dead battery can also trigger the power steering assist fault. Check the battery voltage and make sure it is fully charged.
3. Inspect the Steering Gear and Pump
Examine the steering gear and pump for any signs of damage, leaks, or wear. If there are any visible issues, replace the faulty parts.
4. Reset the Power Steering Control Module
The power steering control module may need to be reset to clear the fault. To reset the module, disconnect the negative battery cable and wait for 15 minutes. Then, reconnect the cable and start the engine.
5. Use a Diagnostic Scanner (OBDII)
If the above steps do not resolve the power steering assist fault, use a diagnostic scanner to retrieve any trouble codes stored in the power steering control module. Based on the codes, you can identify the specific issue and take the necessary steps to fix it.
Can I Drive with a Power Steering Fault Error?
With the power steering fault error, your car is still safe to drive. This warning message only informs you that the power steering assist has been disabled, leaving your steering system still capable of manual operation.
Although when this happens, you will discover that turning the wheel requires much more effort. If you’re used to power steering, it can be challenging, and on long trips, it’s nearly impossible.
