Difficulty turning the steering wheel, especially at low speeds.
A grinding or whining noise when turning the steering wheel.
A loss of power steering assist, making it difficult to control the vehicle.
A warning light on the dashboard that indicates a power steering system fault.

Causes of Power Steering Assist Fault

Low power steering fluid:The power steering system relies on hydraulic fluid to operate. If the fluid level is low, it can cause the pump to cavitate and lose pressure, resulting in a loss of power steering assist.
Faulty power steering pump:The power steering pump is responsible for generating the hydraulic pressure needed to assist the steering. If the pump fails, it can cause a loss of power steering assist.
Faulty power steering rack:The power steering rack is the component that converts the hydraulic pressure from the pump into mechanical force to turn the wheels. If the rack is faulty, it can cause a loss of power steering assist.
Electrical problems:The power steering system is also controlled by an electrical system. If there is a problem with the electrical system, it can cause the power steering assist to fail.

Diagnostic Procedures for Power Steering Assist Fault

Identifying the root cause of a power steering assist fault in a 2012 Ford Fusion requires a systematic diagnostic approach. This involves examining various components and parameters to isolate the issue.

Diagnostic Steps

Visual Inspection:Examine the power steering fluid reservoir for leaks, low fluid levels, or contamination. Inspect the power steering pump, hoses, and belts for any damage or loose connections.
Electrical System Checks:Use a multimeter to test the voltage and continuity of the power steering control module, power steering motor, and associated wiring harness. Check for any open circuits, short circuits, or ground faults.
Power Steering Pressure Test:Connect a pressure gauge to the power steering system and monitor the pressure readings. The pressure should be within the specified range, as indicated in the vehicle’s service manual.
Computer Diagnostics:Use a scan tool to retrieve any diagnostic trouble codes (DTCs) stored in the vehicle’s computer. These codes can provide valuable information about the fault and its possible causes.

Repair and Replacement Options for Power Steering Assist

When faced with a power steering assist fault in a 2012 Ford Fusion, there are several repair and replacement options available. The choice of repair will depend on the specific fault and the severity of the issue.

The most common repair option for a power steering assist fault is to replace the power steering pump. The power steering pump is responsible for providing hydraulic pressure to the steering system, and if it fails, the steering will become difficult or impossible.

Replacing the power steering pump is a relatively simple repair that can be performed in a few hours by a qualified mechanic.

Another option for repairing a power steering assist fault is to replace the power steering rack. The power steering rack is responsible for turning the wheels, and if it fails, the steering will become loose or unresponsive. Replacing the power steering rack is a more complex repair than replacing the power steering pump, but it can be performed in a few hours by a qualified mechanic.

Power Steering Fluid Flush

If the power steering fluid is contaminated or low, it can cause a power steering assist fault. Flushing the power steering fluid is a relatively simple and inexpensive repair that can be performed in a few minutes. To flush the power steering fluid, the old fluid is drained from the system and replaced with new fluid.

Electrical Repairs

In some cases, a power steering assist fault can be caused by an electrical problem. This could be a problem with the power steering control module, the wiring, or the sensors. Electrical repairs can be more complex and time-consuming than mechanical repairs, but they can often be performed without replacing any parts.

Costs and Timeframes

The cost of repairing a power steering assist fault will vary depending on the specific repair required. Replacing the power steering pump typically costs between $500 and $1,000, while replacing the power steering rack typically costs between $1,000 and $2,000.

Flushing the power steering fluid is a relatively inexpensive repair that typically costs less than $100. Electrical repairs can vary in cost depending on the complexity of the problem.

The timeframe for repairing a power steering assist fault will also vary depending on the specific repair required. Replacing the power steering pump or power steering rack can typically be performed in a few hours, while electrical repairs may take longer to diagnose and repair.

Preventive Maintenance and Troubleshooting Tips

Regular maintenance and proactive troubleshooting can significantly reduce the likelihood of power steering assist faults in your 2012 Ford Fusion. Here are some essential tips to keep your power steering system functioning optimally:

Preventive Maintenance

Check and maintain proper fluid levels: Regularly inspect your power steering fluid reservoir and ensure it is filled to the appropriate level. Low fluid levels can lead to insufficient pressure and potential system failure.
Inspect hoses and belts: Periodically examine the power steering hoses and belts for any signs of wear, cracks, or leaks. Damaged hoses or belts can compromise fluid flow and affect steering performance.
Monitor fluid condition: The power steering fluid should be clean and free of contaminants. If the fluid appears discolored, cloudy, or contains particles, it may indicate the need for a fluid change.

Troubleshooting

Check for leaks: If you notice any fluid leaks around the power steering system, it’s crucial to address them promptly. Leaks can lead to fluid loss and diminished steering assistance.
Inspect electrical connections: Loose or corroded electrical connections can disrupt communication between the power steering module and other components. Ensure all connections are secure and free of damage.
Reset the system: In some cases, a simple reset of the power steering system can resolve minor issues. Consult your vehicle’s owner’s manual for specific instructions on how to perform a reset.

Regular Inspections and Maintenance

Regular inspections and maintenance by a qualified mechanic can help identify potential issues early on and prevent more significant problems. Schedule routine checkups to ensure your power steering system is operating correctly and to catch any developing issues before they escalate.

Safety Considerations and Warning Signs

Power steering assist faults can pose significant safety risks, as they can impair the driver’s ability to control the vehicle. It is crucial to be aware of the warning signs that indicate potential problems and to take appropriate actions to ensure safety.
