Common Symptoms of a Ford Fusion Power Steering Assist Fault:

When your Ford Fusion experiences a power steering assist fault, you may notice some or all of the following symptoms:

  • Loss of Power Steering: The most immediate and noticeable symptom. You’ll find it more difficult to turn the wheel, especially at low speeds.
  • Warning Light on Dashboard: Your vehicle’s warning light will illuminate on your dashboard indicating an issue with the power steering system.
  • Inconsistent Steering Wheel Feel: If there’s inconsistency in how stiff or loose the wheel feels when turning it, this can signal a problem.
  • Noise When Turning Wheel: Unusual noises such as creaking or moaning sounds might be noticed during turns, which typically indicate wear and tear in the steering components.

Here is a simple table that summarizes these symptoms:

Loss of Power SteeringHarder to turn wheel, especially at slow speeds
Warning Light on DashboardIndication of an issue with power steering system
Inconsistent Steering Wheel FeelVariations in stiffness or looseness when turning
Noise When Turning WheelCreaking or moaning sounds during turns

It’s important to address these issues quickly to prevent further damage and maintain safe driving conditions.

Causes of Power Steering Assist Fault in Ford Fusion:

There are several reasons why the Power Steering Assist may malfunction in your Ford Fusion. Understanding these causes can help you identify and fix the issue more effectively:

  • Damaged Power Steering Motor: This is often a common cause for power steering assist faults. The motor can wear out over time, or it could be damaged due to poor maintenance.
  • Faulty Sensors: Sensors provide critical data to the power steering system. If they fail, they won’t send accurate information, leading to problems with the system.
  • Software Glitches: Sometimes, an error in the car’s computer software can trigger this fault. A simple update or reset may solve this problem.
  • Low Fluid Levels: Low levels of power steering fluid could lead to difficulty handling your vehicle and potentially damage some parts of the system if not addressed promptly.

Here’s a quick breakdown on how these factors play into causing a Power Steering Assist Fault:

Damaged MotorWear and tear or lack of maintenance can lead to motor failure.
Faulty SensorsInaccurate sensor readings disrupts smooth functioning of power steering mechanism.
Software GlitchesErrors in car computer software leads to wrong signals being sent which triggers fault warning.
Low Fluid LevelsInsufficient fluid levels increases friction between components thus raising chances for potential damage.

Faulty Power Steering Pump:

The power steering pump in a Ford Fusion plays an essential role in making your driving experience smooth and easy. Here are some signs that could indicate a faulty power steering pump:

  • Noisy When Turning: If you hear a whining noise when turning, especially at low speeds, it’s likely the power steering pump is failing.
  • Stiff Steering Wheel: Difficulty in turning the wheel may suggest that the pump isn’t providing enough hydraulic pressure.

If these symptoms persist, consider checking out these common causes of a faulty power steering pump:

  1. Fluid Leakage: The most common cause of failure. Over time, seals can wear out and leak fluid.
  2. Broken Belt: A damaged belt won’t be able to provide the necessary force to drive the pump.

Here’s how both issues affect your car’s performance:

Fluid LeakageLeads to reduced hydraulic pressure which makes it difficult to steer
Broken BeltPrevents proper function of several components including alternator and water pump

To avoid frequent “Power Steering Assist Fault” warnings or potential control loss while driving, regular maintenance checks on your Ford Fusion’s power steering system are recommended.

Low Power Steering Fluid Levels:

The Ford Fusion Power Steering Assist Fault can occur due to low power steering fluid levels. This problem is common and easily identifiable. Here’s why it happens:

  • The fluid serves as a hydraulic medium that makes steering effortless.
  • When the level drops, your car may respond with the fault warning.

Causes of Low Fluid Levels:

There are typically three main reasons for low power steering fluid levels:

  1. Leakage: Leaks in the system can cause a significant drop in fluid levels.
  2. Wear and Tear: Over time, components degrade leading to lower than normal fluid levels.
  3. Neglecting Regular Check-ups: Skipping regular maintenance checks may result in not noticing reduced fluids.
LeakageRapid decrease in fluid level
Wear and TearGradual decrease over long periods
Neglecting Regular Check-upsSudden realization of extremely low or depleted fluids

To avoid getting this fault message, ensure you check your liquid regularly, repair leaks promptly, and replace worn-out parts when necessary.

Issues with the Electric Motor or Sensor:

One common cause of a Ford Fusion Power Steering Assist Fault is problems with the electric motor or sensor. Let’s take a look:

  • Electric Motor Failure: If this component fails, it can’t provide the necessary power for steering assistance.
  • Sensor Malfunctions: Sensors monitor steering input & vehicle speed to determine how much assist is needed. Any error in these readings could trigger a fault warning.
  • Excessive Noise: A worn-out motor often makes loud noises.
  • Reduced Efficiency: The car may require more effort to turn if the motor isn’t functioning properly.
Erratic ReadingsThe power steering behaves inconsistently, sometimes providing too much or too little assistance.
Failure to CommunicateNo noticeable change in steering response despite changes in speed or turning force.

In both cases, immediate professional help should be sought to prevent further complications and potential safety risks while driving your Ford Fusion.

Worn-out or Damaged Drive Belt:

A worn-out or damaged drive belt is a common cause of the Ford Fusion power steering assist fault. This essential component ensures proper functioning of your car’s power steering system.

  • The drive belt, also known as serpentine belt, powers multiple parts in your vehicle including the power steering pump.
  • Over time, due to wear and tear, this belt can get damaged or lose its tension.

Here are some signs that may indicate a faulty drive belt:

  1. Squealing Noise: A high-pitched noise coming from under the hood often indicates a slipping drive belt.
  2. Visual Damage: Cracks, frays or looseness visible on the drive belt suggest it needs replacement.
  3. Steering Difficulty: If you find turning the wheel harder than usual, it could be due to a failing drive belt affecting the power steering pump.
SignsPossible Causes
Squealing NoiseSlipping Drive Belt
Visual DamageOld / Damaged Drive Belt
Steering DifficultyFailing Power Steering Pump


  • Regular inspection and maintenance can prevent damage to your vehicle’s drive belts.
  • Replacing an old or worn out serpentine/drive-belt at regular intervals is necessary for optimal performance of your Ford Fusion’s power steering system.

Replacing these components when they show signs of wear can help avoid further issues with “Power Steering Assist Fault”.

Electrical Problems and Wiring Issues:

When it comes to Ford Fusion’s power steering assist fault, electrical problems and wiring issues are a common cause. Here’s why:

  1. Faulty Battery Connection: A loose or corroded battery connection can interrupt the power supply to the electric power steering system.
  2. Damaged Power Steering Control Module (PSCM): This is the computer that controls your electric power steering system. If damaged, it may lead to a loss of control over your vehicle’s steering.
  3. Wiring Harness Issues: The wiring harness which connects various parts of the electric power steering might be worn out or damaged causing an interruption in communication.

Here are some symptoms related to each issue:

Faulty Battery Connection• Intermittent loss of power steering
• Vehicle starts but dies shortly afterward
Damaged PSCM• Complete loss of power-assisted steering
• Warning lights on dashboard
Wiring Harness Issues• Intermittent operation of electrical systems
• Flickering lights

In conclusion, always check for poor connections, inspect your PSCM regularly and ensure there are no visible damages on your car’s wiring harness.
