In this guide, we will break down the mechanics of the Electric Power Assisted Steering (EPAS) system used in your Fusion. We promise to provide clear, actionable steps to diagnose the problem and explain your options for repair. We will preview the specific diagnostic codes to look for and the tools you will need to get the job done.
Whether you are a seasoned DIY mechanic or a car owner looking to avoid a massive dealership bill, understanding this system is the first step toward a fix. Let’s dive into the technical details of what makes your steering tick and why it might have stopped working.
Understanding the EPAS System in the 2012 Ford Fusion
Unlike older vehicles that used a belt-driven hydraulic pump, the 2012 Ford Fusion utilizes an Electric Power Assisted Steering (EPAS) system. This design eliminates the need for power steering fluid, hoses, and a reservoir. Instead, it uses an electric motor mounted directly to the steering rack to provide the necessary torque for turning the wheels.
The 2012 ford fusion electric power steering pump is technically not a pump at all, but rather a motor and control module assembly. This assembly is often referred to as the Power Steering Control Module (PSCM). It receives data from various sensors, including the steering wheel position sensor and the torque sensor, to determine how much assistance the driver needs.
This shift to electric steering was designed to improve fuel economy by reducing engine drag. However, it introduced a new set of electronic complexities. When the electronics fail, the system typically defaults to a manual steering mode, which feels extremely heavy and difficult to maneuver at low speeds.
The Role of the Steering Rack and Motor
The steering rack is the mechanical heart of the system, converting the rotational motion of the steering wheel into the linear motion that turns the tires. In the Fusion, the electric motor is integrated into this rack. This means that if the motor or the internal sensors fail, you generally have to replace the entire steering rack assembly.
The motor uses a drive belt or a gear set to apply force to the rack. Because this system is entirely electronic, it is highly sensitive to the vehicle’s electrical health. A weak battery or a corroded ground wire can cause the system to shut down even if the mechanical components are perfectly fine.
Why There Is No Power Steering Fluid
One of the most common questions from Fusion owners is where to add power steering fluid. Because this is an all-electric system, there is no fluid to check or change. If a mechanic tells you that you need a “power steering flush” on a 2012 Fusion with EPAS, they are likely mistaken or referring to a different vehicle model.
This “dry” system is cleaner and requires less maintenance under normal conditions. However, it also means that you cannot fix steering stiffness by simply topping off a reservoir. Troubleshooting requires a digital approach, often involving an OBD-II scanner with the capability to read chassis codes.
Common Symptoms of a Failing 2012 ford fusion electric power steering pump
When the steering system begins to fail, the symptoms are usually immediate and hard to ignore. The most common sign is the “Power Steering Assist Fault” or “Service Power Steering Now” message appearing in the message center of your instrument cluster. This is often accompanied by a total loss of power assistance.
You might also experience intermittent assistance, where the steering feels light one moment and heavy the next. This is frequently a sign of a failing torque sensor or a loose electrical connection. In some cases, the steering wheel may vibrate or “shudder” when you are making a turn at low speeds.
Another symptom is the steering wheel failing to return to the center position after a turn. This can indicate a mechanical bind within the rack or a calibration issue with the internal electronics. If you hear a grinding or whining noise when turning, it may point to a physical failure of the motor’s internal drive mechanism.
The Infamous Pulling or Drifting
Some owners report that the car feels like it is pulling to one side, even after a wheel alignment. This can happen if the torque sensor inside the steering rack is sending incorrect data to the control module. The system may “think” you are trying to turn when you are actually holding the wheel straight, causing it to apply unneeded assistance.
This pulling sensation is not just annoying; it can be a safety hazard on the highway. If the EPAS system applies sudden, unexpected torque to the steering wheel, it can catch a driver off guard. This specific behavior was one of the primary reasons for the federal investigations into Ford’s steering systems.
Sudden Loss of Assistance While Driving
Perhaps the most dangerous symptom is the sudden loss of steering help while the vehicle is in motion. While the car can still be steered manually, the effort required is significantly higher than a traditional car without power steering. This can be particularly difficult for drivers during tight turns or emergency maneuvers.
If this happens to you, the best course of action is to maintain a firm grip on the wheel and steer the vehicle to a safe location. Do not panic; the mechanical link between the steering wheel and the tires remains intact. The car will still steer, it will just require substantial physical effort to turn the wheel.
Safety Recalls and Manufacturer Extended Warranties
The 2012 ford fusion electric power steering pump system has been the subject of significant safety recalls. Specifically, Recall 15S18 (NHTSA Campaign Number 15V340000) was issued to address a potential loss of power steering assist. This recall affected hundreds of thousands of vehicles across the Ford and Lincoln lineups.
The root cause was identified as a potential fracture in the internal circuit board of the PSCM. This fracture could occur due to thermal cycling or vibration, leading to a loss of communication within the system. If your vehicle is covered under this recall, Ford dealerships are required to perform the repair at no cost to you.
It is crucial to check your Vehicle Identification Number (VIN) on the NHTSA website or Ford’s owner portal. Even if you are the second or third owner, recall repairs are free of charge. Some vehicles that were not part of the initial recall were later covered under “Customer Satisfaction Programs,” which extended the warranty on the steering rack.
What the Recall Repair Involves
Depending on the specific diagnostic codes found by the technician, the recall repair may involve a software update or a full replacement of the steering rack. If the system has already stored a permanent failure code (like U3000), the dealership must replace the entire rack assembly.
The software update was designed to provide a “limp home” mode. Instead of shutting down completely, the updated software allows for a more gradual reduction in assistance, giving the driver more time to react. However, many owners found that the software update was merely a temporary fix for a hardware problem.
Dealing with Out-of-Warranty Failures
If your Fusion does not fall under the recall or the extended warranty period has expired, the cost of repair can be significant. A new OEM steering rack can cost upwards of $1,000 for the part alone. Labor can add several hundred more, as the subframe often needs to be lowered to access the rack.
Before paying out of pocket, contact Ford Customer Relationship Center. In some cases, they may offer “goodwill” assistance if the vehicle has low mileage or a documented history of steering issues. It never hurts to ask, especially given the well-documented history of these specific steering components.
Diagnostic Steps for the Home Mechanic
If you are a DIYer facing a steering fault, the first tool you need is a high-quality OBD-II scanner. Standard scanners that only read engine codes (P-codes) may not be enough. You need a tool that can access the Chassis (C) and Network (U) codes stored in the PSCM.
Common codes associated with a 2012 ford fusion electric power steering pump failure include:
- U3000: Control Module Internal Failure. This is often a “death sentence” for the rack and usually requires replacement.
- C0051: Steering Wheel Position Sensor. This might indicate a calibration issue or a failure in the clockspring/sensor area.
- P07A3: Power Steering Control Module Performance. This often points to voltage issues or internal motor faults.
Before condemning the rack, check the basics. Inspect the battery and the charging system. The EPAS system can pull over 60 amps of current during heavy maneuvering. If your battery is more than three years old or your alternator is struggling, the steering module may shut down to protect the rest of the electrical system.
Checking Grounds and Connections
Corrosion is the enemy of electronics. Locate the main ground strap for the steering rack and ensure it is clean and tight. A poor ground can cause “ghost” codes and intermittent steering loss. You should also inspect the large electrical connectors plugging into the rack for signs of water intrusion or backed-out pins.
Use a digital multimeter to verify that the rack is receiving full battery voltage. Test this while someone else turns the steering wheel (with the engine running), as this is when the current draw is highest. If the voltage drops significantly, your problem might be the wiring harness or the battery rather than the steering rack itself.
Resetting the System
Sometimes, a simple system reset can restore assistance, at least temporarily. Disconnecting the negative battery terminal for 15 minutes can clear the volatile memory in the modules. However, if a permanent fault code like U3000 is present, the light will likely return the moment you start the car.
For a more thorough reset, tools like FORScan (a software specifically for Ford vehicles) can perform a “Module Reset” or a “Self-Test” on the PSCM. This software is a favorite among Ford enthusiasts because it provides dealership-level access for a fraction of the cost. It can also be used to calibrate the steering angle sensor after a repair.
Step-by-Step Guide to Steering Rack Replacement
Replacing the steering rack on a 2012 Ford Fusion is a labor-intensive task that requires a good set of tools and a safe working environment. If you decide to tackle this yourself, plan for a full day of work. You will need to support the engine and lower the rear of the subframe to gain enough clearance.
- Safety First: Park the car on a level surface, engage the parking brake, and disconnect the battery. Jack up the front of the vehicle and support it securely on jack stands. Never work under a car supported only by a floor jack.
- Disconnect Steering Linkage: Inside the cabin, remove the bolt connecting the steering column to the rack’s input shaft. Ensure the steering wheel is locked or strapped in place to prevent it from spinning, which could break the clockspring.
- Remove Outer Tie Rods: Remove the front wheels and disconnect the outer tie rod ends from the steering knuckles. You may need a tie rod puller or a pickle fork if they are stubborn.
- Lower the Subframe: Support the subframe with a jack. Remove the rear subframe bolts and loosen the front bolts. Carefully lower the rear of the subframe a few inches. This provides the “window” needed to slide the old rack out.
- Swap the Rack: Disconnect the electrical connectors from the rack. Remove the mounting bolts holding the rack to the subframe. Maneuver the old 2012 ford fusion electric power steering pump assembly out through the wheel well or the gap in the subframe.
When installing the new rack, ensure all bolts are torqued to the manufacturer’s specifications. It is highly recommended to use new mounting hardware, as many of these bolts are “torque-to-yield” and should not be reused. Once the mechanical installation is complete, the job is not yet finished.
The Importance of Programming (PMI)
A new or used steering rack will not work immediately upon installation. The PSCM must be programmed with your vehicle’s specific As-Built data. This process is called Programmable Module Installation (PMI). It tells the steering module the car’s weight, tire size, and other parameters needed for proper assistance.
If you are a DIYer, you can perform this using FORScan and a compatible OBD-II adapter (like the OBDLink EX). You will need to download your car’s As-Built data from the Ford Service website and upload it to the new module. Without this step, the steering will likely remain disabled, and you will have a “Configuration Incomplete” error code.
Post-Installation Alignment
After replacing any steering component, a professional wheel alignment is mandatory. Even if you carefully measured the tie rod lengths, the geometry will be slightly off. Driving without an alignment will cause rapid tire wear and may interfere with the Electronic Stability Control (ESC) system.
Inform the alignment technician that you have replaced the steering rack. They will need to perform a “Steering Angle Sensor (SAS) Reset” as part of the alignment process. This ensures that the car’s computer knows exactly where the “straight ahead” position is, which is vital for the lane-keep assist and stability systems.
Frequently Asked Questions About 2012 ford fusion electric power steering pump
Can I drive my Ford Fusion if the power steering fails?
Technically, yes, the car remains mechanically steerable. However, it requires significantly more physical effort, especially at low speeds or when parking. For safety reasons, it is not recommended to drive the vehicle long-term in this condition, as your ability to perform emergency maneuvers is severely compromised.
Is there a fuse for the electric power steering?
Yes, there is a high-amperage “mega-fuse” located in the Battery Power Distribution Box under the hood. It is usually an 80-amp or 100-amp fuse. If this fuse is blown, you will lose all steering assistance. However, these fuses rarely blow without a major short circuit or a catastrophic internal failure of the steering motor.
Can I replace the electric motor without replacing the whole rack?
On the 2012 ford fusion electric power steering pump assembly, the motor and the steering rack are designed as a single integrated unit. While some specialized shops might attempt a rebuild, for the average DIYer or independent mechanic, the only reliable solution is to replace the entire rack and motor assembly as one piece.
How much does it cost to fix the power steering on a 2012 Ford Fusion?
If the vehicle is covered under a recall, the cost is $0. If you are paying out of pocket at a dealership, expect to pay between $1,500 and $2,200 for parts and labor. An independent shop using a high-quality remanufactured rack might charge between $900 and $1,300. DIYers can often complete the job for $500 to $700 in parts and software tools.
What is the difference between a “Power Steering Assist Fault” and “Service Power Steering Now”?
Generally, a “Fault” message indicates a detected problem that may be intermittent or related to a sensor. “Service Power Steering Now” usually indicates a permanent failure that has caused the system to shut down entirely. In both cases, the diagnostic codes stored in the computer will provide the most accurate information.
Final Thoughts on Maintaining Your Fusion’s Steering
Dealing with a 2012 ford fusion electric power steering pump issue can be stressful, but understanding the system empowers you to make the right decision.
