Symptoms of Power Steering Assist Fault

Before we dive into the troubleshooting process, let’s take a closer look at the symptoms that typically indicate a power steering assist fault:

  1. Hard-to-Turn Steering Wheel: If you find yourself struggling to turn the steering wheel, especially at low speeds or during parking maneuvers, it is likely due to a power steering assist fault.
  2. Steering Wheel Vibration: A vibrating steering wheel, particularly when driving at higher speeds, can be another indication of a power steering problem.
  3. Power Steering Warning Light: The power steering warning light illuminated on your dashboard is a clear indication that there is an issue with your power steering system.
  4. Burning Smell: If you notice a burning smell coming from the engine while driving, it could be a sign of a power steering fluid leak or a failing power steering pump.

If you experience any of these symptoms, it’s crucial to address the problem promptly to ensure your safety on the road.

Causes of Power Steering Assist Fault

To effectively troubleshoot and fix a power steering assist fault, it’s essential to understand its potential causes. Here are some common culprits:

  1. Low Power Steering Fluid Level: Inadequate levels of power steering fluid can cause a loss of hydraulic pressure, resulting in a power steering assist fault.
  2. Faulty Power Steering Pump: A failing or malfunctioning power steering pump may not provide sufficient hydraulic pressure to assist with steering.
  3. Bad Steering Rack: A worn-out or damaged steering rack can contribute to power steering problems, leading to difficulties in turning the wheel smoothly.
  4. Loose or Damaged Power Steering Belt: If the power steering belt is loose, damaged, or worn, it may not properly transmit power from the engine to the power steering pump, affecting the system’s performance.

By identifying the root cause of the power steering assist fault, you’ll be better equipped to tackle the issue and implement an appropriate solution.

How to Fix Power Steering Assist Fault

Now that we have a grasp of the symptoms and causes, let’s move on to the step-by-step process of troubleshooting and fixing the power steering assist fault in your Ford Fusion.

1. Check Power Steering Fluid Level

The first step is to inspect the power steering fluid level. Follow these instructions:

  1. Locate the power steering fluid reservoir in your Ford Fusion. It is typically labeled and situated near the engine bay.
  2. Remove the reservoir cap and check the fluid level. It should be within the recommended range specified in your vehicle’s owner’s manual.
  3. If the fluid level is low, add more power steering fluid carefully. Be sure to use the type of fluid recommended by the manufacturer.
  4. Once you’ve added the necessary fluid, replace the reservoir cap securely.

After verifying the power steering fluid level, start the engine and turn the steering wheel from one end to the other. Pay attention to any improvements in the steering effort and fluid noise. If the power steering assist fault persists, proceed to the next step.

2. Inspect Power Steering Pump and Belt

Next, we need to examine the power steering pump and belt for any potential issues. Here’s what you should do:

  1. Inspect the power steering pump for signs of leaks or visible damage. Look closely at the pump housing, hoses, and fittings.
  2. If you notice any leaks or damage, it is likely that the power steering pump needs to be replaced. Consult your vehicle’s service manual or seek professional assistance if necessary.
  3. Additionally, examine the power steering belt for wear, cracks, or looseness. A worn or damaged belt may slip and prevent the power steering pump from operating correctly.
  4. If the power steering belt shows signs of wear or damage, and the tension is not correct, consider replacing the belt or adjusting its tension accordingly.

Addressing any issues with the power steering pump or belt will help ensure proper functioning of the power steering system. However, if the problem persists, move on to the next step.

3. Check Steering Rack

A faulty steering rack can also contribute to a power steering assist fault. Follow these steps to inspect the steering rack:

  1. Visually inspect the steering rack for any signs of leaks or damage. Look for traces of power steering fluid around the rack assembly.
  2. Check for loose or damaged components within the steering rack. Pay attention to any excessive play or unusual noises when turning the steering wheel.
  3. If you detect leaks, damage, or loose components, it may be necessary to replace the steering rack entirely. Consult your Ford Fusion’s service manual or contact a certified technician for guidance.

Dealing with any steering rack issues promptly will ensure the integrity and safety of your power steering system. However, if the problem still persists, there is one final troubleshooting step you can try.

4. Reset Power Steering Control Module

Sometimes, resetting the power steering control module can resolve power steering assist faults. Here’s how you can perform a reset:

  1. Disconnect the negative terminal of your Fusion’s battery and wait for at least 15 minutes. Ensure that you have the necessary tools to disconnect and reconnect the battery safely.
  2. After 15 minutes, reconnect the negative terminal of the battery and ensure it is securely fastened.
  3. Start the engine and turn the steering wheel all the way to the left and then all the way to the right.
  4. Repeat this process a few times to allow the power steering control module to recalibrate.
  5. Finally, test the steering wheel to see if the power steering assist fault has been resolved.

Resetting the power steering control module can often clear any underlying issues with its software or calibration. If this step does not resolve the problem, it may be time to consult a professional mechanic for further diagnosis and repair.

Preventing Power Steering Assist Fault

Now that you’ve successfully addressed the power steering assist fault in your Ford Fusion, it’s important to take preventative measures to avoid future occurrences. Here are some steps you can take:

  1. Regularly check the power steering fluid level: Make it a habit to inspect the power steering fluid level and top it up if necessary. Follow the recommended guidelines provided in your vehicle’s owner’s manual.
  2. Replace power steering fluid periodically: Over time, power steering fluid can become contaminated and lose its effectiveness. By replacing it at the recommended intervals, you can maintain optimal performance of the power steering system.
  3. Inspect power steering pump and steering rack: Regularly examine the power steering pump and steering rack for leaks, damage, or signs of wear. Catching potential issues early on will prevent them from developing into more significant problems.
  4. Replace power steering components as necessary: If any power steering components show signs of failure, such as leaks, excessive play, or noise, it’s crucial to replace them promptly to ensure your safety and prolong the lifespan of your power steering system.

By following these preventative maintenance measures, you can minimize the risk of encountering a power steering assist fault in the future and enjoy worry-free driving.
