How to Fix Power Steering Assist Fault Ford Escape – Useful Manual

To have steering problems is frightening and should be handled right away. The most typical reason for poor power steering is a lack of power steering fluid.

A power steering assist is a mechanical device that enhances vehicle handling by lowering the force required to move the wheels. It is an important component that aids in driving and moving automobiles.

Drivers must compensate for the lack of assistance by being more attentive to their surroundings if it fails. Power steering works by directing power from your engine to your front wheels via a hydraulic system.

Drivers must understand how to fix power steering assist fault ford escape in order to repair it.

This guide will go through the power steering assist system and have a peek at what could be causing the issue.

What Is Power Steering Assist and How Does It Work?

Power steering assist is an electronic feature of an automobile that allows the steering system to attempt to help some drivers overcome their difficulties with steering control.

Power steering is concerned with the loss of energy imparted to the steering wheel during acceleration and the gravity in a car. Power steering assist is driven by power or an electric motor. The increase in consumption and driver behavior from great accelerations may be diminished.

Without power assist, the steering of most vehicles would be extremely heavy, particularly during low-speed maneuvers.

Power steering works by directing power from your engine to your front wheels via a hydraulic system. Some power steering failures arise as a result of contaminated hydraulic fluid or dirty components restricting the passage of hydraulic fluid to your assistant.

When the driver presses on the power steering button, the power steering assist activates. A motor inside the vehicle activates the power steering assist’s mechanism. This mechanism turns the steering wheel and tries to move the vehicle in the direction you’re trying to drive it.

This way, you can make turns easily and safely. The power steering assist also minimizes the chance of your vehicle rolling over during turns.

Power Steering Assist Fault Causes

There are various things that may go wrong with your steering, and if they do, you may be stuck attempting to operate your vehicle without the aid of this crucial equipment.

1. Fluid Contamination

The power steering aid is only effective when the hydraulic fluid is clean. If the steering fluid is contaminated, it might cause harm to equipment such as the pump. Furthermore, unclean fluid might render numerous components, including the power steering assist system, inoperable.

The car’s owner manual recommends changing the power steering fluid every “N” amount of time set by the manufacturer.

2. Causes in fluid level

An automobile requires hydraulic fluid to steer whether utilizing a hydraulic power steering system or a fluid-electric hybrid system.

Power steering systems require specific fluid amounts to function properly. If you use too much pressure in your power steering system, the excessive pressure may cause seals and valves to fail. Furthermore, your automobile will not turn if you do not have adequate fluid in your system.

When your power steering system leaks, the fluid evaporates, rendering the steering inoperable. To avoid this, it is vital to have a regular timetable for refilling the fluid.

3. Belts that may be torn

When actuated, power steering systems draw power from the engine. This is due to the fact that power steering belts must remain operational even when switched on.

Any damage to the power steering system’s hoses, belts, or other components causes the system to fail quickly. This is due to the fact that the engine and power steering pump are linked by a pulley, and frayed or corroded belts or hoses cause the system to fail. The system will not endure long if any of its components are damaged, frayed, or rusted.

Power steering belts should be replaced when they exhibit symptoms of wear, aging, or damage. Belt checks should be conducted at every automobile maintenance session.

4. Failure of the Steering Wheel Pump

Pumps are used in both traditional and electric power steering systems. However, the two system implementations work differently. Fluid flow cannot be disrupted if a pump fails.

Because the power steering relies on it, the power steering pump is the most important component.

Whenever you drive your car, this important piece of equipment will be used. While pumps are very durable, they can wear out and need to be replaced.

A failing pump can make a lot of noise when you spin the wheel. This is an indication that the pump is approaching an early demise.

5. Excessive Force

Power steering can survive harsh road conditions such as potholes and shock-mounted wheel bumps. However, power steering is not without flaws.

When steering system components like belts and pumps are strained, they can burst fast.

Avoid difficult roads unless you have an off-road car or four-wheel drive vehicle equipped with a steering pump built for harsh terrain or avoid very rough roads. Those who do not possess these automobiles should avoid driving on exceptionally bumpy roads.

Common Causes of Ford EPAS Failure

The Escape 2008 and subsequent models use electric-assist power steering. The system uses a power steering control module or PSCM an electric motor, a steering angle sensor, a torque sensor, and a steering wheel position sensor as well as various angle sensors to generate the required steering effect.

To make fuel-efficient vehicles, the EPAS (Electronic Protocols Application Software) was developed to replace the hydraulic steering system. It assists the steering rack with a motor and only activates when the steering wheel is turned.

However, Ford’s EPAS technology has had several severe issues that have hampered the driving experience. The problems are caused mostly by steering torque sensors and steering position sensor failures.

The cost to fix a power steering assist fault

Power steering repairs can cost anywhere from $15 to $530 they increase in price depending on the diagnosis. Replacing a fuse or adding steering fluid to the system is an affordable way to repair the failure.

But the exact price depends on what exactly went wrong with the system. For example, if you only need to replace the hose, you will only spend $60 to $150 on the parts and more on labor.

Sometimes the problem is the motor that provides the mechanical power steering or a loose connection between the motor and the steering wheel. These can be repaired on a DIY basis with little or no cost. The total cost of replacing the motor is about $250.

Power Steering Assist Fault Signs

  • Warning light on the dashboard.
  • Strange sounds while turning.
  • At low speeds, steering wheel trouble.
  • Whining sound upon starting the car.
  • Hydraulic fluid leaks are seen beneath the vehicle.

How to fix the Ford power steering assist fault

In 2005, Ford introduced its breakthrough electric power-assisted steering (EPAS). This invention brought with it both benefits and difficulties.

Car owners need to understand how to identify and fix power steering assist fault in order to repair it.

Ford’s power-assisted steering is a malfunction that makes driving difficult for people who can’t safely pilot their vehicles. Below are some solutions to this problem that you can try yourself.

1. Check for power steering fluid level

Refill your power steering fluid reservoir when necessary to ensure proper functionality of the power assist. This usually indicates a low fluid level, which can be identified by checking the fluid’s specific gravity.

It’s a good idea to inspect the power steering and replace the power steering pump if everything appears to be working properly.

Regular inspection of vehicle fluids can help a person notice problems with their car before they become major maintenance expenses. Checking vehicle fluids at least once every oil change interval makes it easy to find problems and fix them before they become big problem.

2. Change the steering angle sensor

Although error codes indicate a problem with the steering angle sensor, a wheel alignment that appears perfect indicates a need to replace the sensor.

The steering angle sensor in most versions must be changed by removing the steering wheel.

3. Change the torque sensor

The torque sensor package includes instructions for removing the upper and lower steering column. Make sure that the steering shaft keyway slot is aligned with the diamond-shaped mark on the sensor’s body before removing the previous torque sensor.

It is critical to note that even little movements might cause the steering column to slide out of place.

4. Repairing an Electrical Fault

Many of these common electrical faults in automobiles are rather simple to repair. Replacement fuses and spark plugs are available at your local auto supply store. If you locate any frayed or broken connections or wires, it’s time to replace them.

For more difficult electrical difficulties, you may need to consult a professional to have the problem properly rectified.

5. Swap Power Steering Pump

You should just need basic hand tools to swap your power steering pump. However, some specialized flare-nut wrenches and a specialized tool for carefully removing the pulley from the pulley shaft will make the job much easier.

These are normally available for hire or borrowing from the same car parts retailer that sells you the new pump. Otherwise, take it to a nearby vehicle repair shop for assistance.

Is a power steering assist fault a serious problem?

While power steering assist fault issues aren’t as dangerous as head gasket failures, they should still be addressed immediately. Looking into these issues is a good idea since it doesn’t damage your head the way a head gasket failure can.

When you ignore a mechanical problem, you risk damaging your steering system. Instead, you’re more likely to experience serious problems with your vehicle.

Power steering is required to effectively steer a car without any control issues.

Hydraulic Power Steering system

The name hydraulic power steering lends itself to the use of hydraulic fluid pushed by an engine-driven pump.

Technological advancements in this field have proven useful to car manufacturers for the past 50 years. The constant operation of the pump drains unnecessary energy from the engine, even when the car is on a straight course and doesn’t need any help.

Regular upkeep and regular line replacement are required for the hydraulic power assist. Any leaks in the hydraulic system render the power assist inoperable. It’s still possible to drive a vehicle without power steering, just with reduced assistance from the system.

Electric Power Steering system

Modern automobiles commonly use electric power steering or EPS. The steering wheel still connects to a metal steering shaft its function is to steer tires as the rack controls the vehicle.

An electric power steering requires electricity pulled from the vehicle’s electrical system to work. This can be accomplished through a motor that’s mounted on the steering column or rack.

A computer monitors the torque sensor, which measures how hard the driver is steering. The computer determines how much assistance is needed based on this information.

Many vehicles utilize a microchip that automatically adjusts the amount of steering effort required. This allows for easy turning at low speeds but provides a heavier turn when traveling faster. The added stability and control this provides give the driver a sense of confidence.

The advantages of an Electric Power Steering System

  • Increases fuel economy by a few percentage points.
  • Because the electric motor only pulls power when needed, hydraulic fluid maintenance is eliminated.
  • Electric power steering enables any driver-assist or convenience function that includes spinning the wheels without the driver’s involvement.
  • Lane-keep assist, automatic parking and lane changes, and the ability to lead the car around obstacles are all features that make use of EPS’ capacity to steer itself when appropriate.


How much does it cost to fix the power steering assist fault?

Depending on the diagnosis, power steering failure repairs might cost anywhere from $10 to $530 or more. If all you need to do is add some steering fluid to the system or replace a fuse, your repair costs will be minimal.

The problem is sometimes the motor that supplies mechanical power steering or a loose connection between the motor and the steering wheel.

What does steering assist fault service required to mean?

The Power Steering Assist Fault warning indicates that your electrical or mechanical power steering system is malfunctioning.

The cure might be as simple as replenishing power steering fluid or addressing an electrical defect, but it could also be the result of a more serious problem.
