Power steering has made driving easier and safer since it was introduced to automobiles. It gives the driver more control over the vehicle and better maneuverability.

Hydraulic power steering and a power steering assist system are both included in the power steering system. A power steering assist fault alert will be displayed if it malfunctions. So how do you solve a power steering assist problem when it happens?

What Is Power Steering Assist?

Power Steering Assist Fault

There was just one way to steer a car in the old days. You put your hands on the wheel with both of your hands and give it your all.

In 1951, power steering was installed for the first time. The steering was assisted by hydraulic power. A 1951 Chrysler Imperial was the vehicle in question. For the following 50 years, this technology was relevant.

EPAS is now available to us. For electric power steering, this is the abbreviation to use. Hydraulic fluid and a pump are still required for this to function. Instead of using the engine’s energy to pressurize the fluid and assist with steering, this system uses an electric pump.

How Does It Work?

Hydraulics are used to operate the system. The question is, how does it work and how accurate is it?

Components both tiny and large work together to provide precision. When the steering wheel is pushed in a certain direction, the fluid in the reservoir is pumped. The force applied to the steering wheel is transferred and amplified by the hydraulic fluid before it reaches the wheels on the road.

Until recently, the engine was employed to power the pump. It was attached to the engine by a belt and used the engine’s power to run the pump. Modern electric pumps generate the energy needed for the pump itself.

A great deal of power was sucked up by the extra belt attached to the engine. Despite the fact that you aren’t driving, the belt is still attached. As a result, the system as a whole becomes inefficient. This problem is solved by the use of an electric pump.

The electric pump uses the battery’s energy when necessary, making the overall system more effective.

If you’re driving with a PAS system, you’re basically getting power steering. In the past, we used a system that relied solely on hydraulic fluid and engine power. Electric pumps are becoming more frequent in hybrid systems.

The EPAS is another feature of power steering. There is no hydraulic system required for this. In recent years, this has become a more common characteristic in the technology landscape. New steering systems like the EPAS steering system are the inspiration for many of the car’s new functions, like lane-keeping assistance, parallel parking assistance, and cornering assistance.

Why Does A Power-Assisted Steering System Fail?

Power Steering Assist Fault-2

The components of your car’s power assisted steering system will vary depending on the type of system you have. As a result, not all power assisted steering systems will experience the issues we mention below.

The steering wheel is the sole thing that gives you any control over how fast or slow your car moves. When the car needs to be stopped, the brakes and engine work together to get it there. The steering, on the other hand, is what keeps the vehicle in check. As a result, it requires extra care and upkeep.

Here are some of the most prevalent issues with the power steering assist system.

Electrical Malfunctions

This has nothing to do with the system’s hydraulics. A problem with the electrical system could be the cause of a difficult time turning the wheel. If your fluid levels are fine but you’re still experiencing this issue, it’s possible that your electrical system is to blame.

Pressurized fluid is not used for turns when an electrical pump malfunctions in an assist system. Because you’re not getting any turn-assistance, the steering is tighter as a result.

Use an OBD 2 scanner to quickly identify the problem. You should be able to figure out exactly what’s wrong by doing this.

The only way to find out if there’s a problem without one of these gadgets is to check about. The fuse box and the cables connecting to the steering system should be checked out.. There is a chance that something out of the ordinary is to blame. Continue to the battery and measure its voltage there if necessary.

If nothing has gone wrong so far, the code may be the result of an abnormality. Either the warning light or the power steering system’s electronics are at blame, or it could be something else entirely.

Restart your vehicle two or three times to see if that helps. Resetting the warning light or possibly resolving the issue can be accomplished by doing this. However, keep in mind that this is only a band-aid solution. You should have your car inspected as soon as possible.

Running Low On Fluids

Hydraulic fluid is required to run a hydraulic power steering system or a fluid electrical hybrid power steering system. A lack of regular steering fluid top-ups could leave you in danger of running out.

A lack of fluids and an inability of the hydraulic system to transfer energy to the wheels are likely causes of steering that requires five times as much effort to turn.

Check your gasoline level promptly if you feel it is low. When your automobile is still warm, it’s not a good idea to check the gasoline level. Before you can check the fluid levels, you’ll need to start it up and let it warm up. If you don’t do this, you won’t be able to see how much fluid is left in your vehicle.

Power steering system components might be damaged by driving with low fluids. To go through this drive without having to check the fluid levels, you might imagine that you can just brute force your way through it. If you don’t know what you’re doing, you might be able to fix it, but you might have to replace the entire steering system.

Rough When Turning

Your steering wheel may make grinding noises on occasion. This isn’t a big deal, and it’s usually a simple fix. However, at times, the noises could be frightening or unpleasant.

The belt drive is a common cause of this issue. Power steering pulleys should be checked. If you hear grinding noises, the first thing you should do is inspect the gearbox. Even if you aren’t in danger right now, grinding noises are a warning sign that trouble is on the way.

It’s not difficult to make the necessary repairs. Hire a friend to help you jack up your vehicle and then take control of the wheel whenever you want. While he’s rotating the wheel, you can go under and look at the belt. Tighten it if it seems to be slipping, then adjust it as necessary.

Fluid Leaks

Leaks in the power steering fluid might potentially lead to a breakdown in the power steering assist. A pool of oil in your driveway isn’t the only sign of a problem with your power steering system. After the leak, there are more pressing matters to consider.

Leaks in the power steering fluid can drastically reduce the steering system’s performance in a matter of minutes. When you’re driving, this could happen. You may run out of fluids while driving.

It will take some time to get used to driving without power assisted steering because you are so used to it. When you lose control of your vehicle while driving, you put yourself and everyone else on the road at risk.

In most cases, the color of steering fluid is red or pink. Transmission fluid is the same hue as this. You can tell whether you have a steering fluid leak by looking at where the fluid is leaking. A puddle under your engine will result from a steering fluid leak.

In contrast, transmission fluid leaks tend to be located in the centre of the vehicle.

How To Solve Power Steering Fluid Leaks?

A leak should be investigated as soon as possible if you notice it. Some of the most prevalent culprits for steering fluid leaks include worn out seals and worn out seals.

Take a look at the steering fluid hoses. If they’re worn out or damaged, they’ll need to be replaced The seals are another vulnerable location. Make sure there aren’t any slack straps or screws.

Proceed to the fluid pump if you discover any leaks. The pump itself can malfunction, so make sure to check the main rack first.

Snapped Belt

With an electrically powered assisted steering system, you’ll be using a belt that is attached to the crankshaft. Despite the fact that they are so rare, they eventually lose their integrity. The belt could break as a result of this. Another possibility is that they’ll trip and fall.

Pump failure occurs when the belt is disconnected from the crankshaft, as it is no longer able to generate sufficient power. You’ll have to put in more effort per turn if you don’t have a pump.

Having your power steering assist fail in this manner is among the worst possible outcomes. The driver is shaken up because everything happened so suddenly. It’s difficult to keep the car under control when you’re unable to easily operate it.

You can try to reinstall the belt if it has slipped. Regardless of whether the belt has snapped or slipped, the best remedy is to replace it. Using the same belt that slid because of a problem with the belt could cause it to slip again.

A common cause of power steering assist failure is one of these. The question of how to cure a power steering assist defect becomes a lot easier to answer once you have a basic understanding of the issues and potential solutions. shouldn’t worry you anymore.

Automobiles In Which Power Steering Assist Fault Is Common

Despite the fact that this is not a typical occurrence, certain car types do suffer from it on occasion. Steering problems are the last thing you want to deal with.

A general knowledge of frequent causes and solutions for this problem might help you avoid or cope with the issue linked with a particular model.

Ford Fusion Power Steering Assist Fault

Because of this problem, the Ford Fusion was issued a recall. The difficulty was that the bolts did not have the required coating to protect them. Because of this, they were more likely to rust. Motor detachment occurred as a result of this.

Steering systems will lose their power-assisted feature if this occurs. This makes it more difficult to spin the steering wheel at low speeds. Due to this issue, Ford Fusion models from 2013 to 2016 were recalled. Hermosillo, Oakville, or Salt Lake Assembly facilities manufactured the recalled Fords.

Wax was applied to all of the bolts during the recall, and if necessary, new bolts were installed.

Ford Focus EPAS Issues

The EPAS on the 3rd generation Ford Focus is cutting-edge (Electronic Power Assisted Steering). The Ford Focus is known to have problems with this system. The particular malfunctioning component is unknown. When a component in your electric power steering system fails, you will be unable to steer.

The 3rd generation Ford Focus has a well-documented power steering problem that frequently renders the vehicle inoperable. There is a silver lining here: This is a condition that occurs most frequently at modest speeds, between 10 and 20 miles per hour. As a result, EPAS-related fatalities are rare.

It’s unclear if Ford will remedy the issue or issue a recall at this time.

Ford Flex Power Steering Assist Failure

The electric power steering system has been known to malfunction in a small number of Ford Explorer models. The 2013 Ford Flex has a lot of this.

When this happens, it’s normally at modest speeds. No one knows why the experiment failed, and there is no explanation for this either. It has been suggested that a new relay system may be the solution to many of these issues.

These are just a few of the vehicles for which power steering assist has been a problem in the past. This problem has long been associated with Ford. Even the Ford Escape has had power steering failure concerns.

How To Reset Power Steering Fault Code?

You should never overlook the dash notification indicating a power steering failure. To avoid using it while driving, you can follow the steps outlined below to reset it.

That alarm can be easily reset by restarting your automobile. Turn on and off all of your vehicle’s systems. Your car’s electrical systems will be reset as a result of this procedure. The power steering assist malfunction alert can be removed by repeating the procedure 2 or 3 times.

When it comes to driving, the power steering system is a critical part of the equation. When this fails, it raises serious concerns about the safety of the user. Since the steering system is critical, you should not ignore any warnings about it. When you have the opportunity, have it examined.

The problem will not be solved by resetting the codes. There is an early warning system in the form of the power steering assist failure alert. Indicating that the power steering system may be out of order, Resetting the code and ignoring it will compromise the drive’s security.

If you don’t take action, the notice will reappear. You’ll lose your power steering if you keep resetting the alert every time it appears.


Have you ever wondered how to fix power steering assist? Here are a few of the most often asked questions.

What Causes Power Steering Failure?

Even though there are numerous possible causes for power steering failure, you can usually limit it down to one of the following.

Steering wheel failures are most often caused by one of these three factors. Pump failure, deterioration of hoses, or the intrusion of air into the steering fluid system can all cause the fluid to become contaminated.

How To Identify Steering Fluid Leak?

It is necessary to go through this procedure if you see a pool of liquid on the ground when you take your car out of the garage and are wondering if it is steering fluid.

The first thing to notice is the color. It’s either pink or red when it comes to steering fluid. There is antifreeze, as well. Next, consider the surface’s sheen. Antifreeze is out of the picture if it’s slimy. Smell the fluid if it’s brownish. There will be a burnt smell to dirty transmission fluid.

If you’re still stumped as to what the puddle of liquid is, have a look at where it came from. If the leak is near the engine, steering fluid is most likely the culprit. This is a sign of transmission fluid leakage.

How To Identify Steering Fluid Leak?

Power steering fluid should be replaced every four years or 50,000 miles, whichever comes first. When it’s all said and done, The power seeing fluid should be replaced as soon as possible if it appears to be tainted or brown, rather than waiting four years.

What Happens When You Drive With Low Power Steering Fluid?

Driving with low power steering fluid is not recommended for a reason. Ineffective lubrication and cooling of the steering system will occur if the power steering fluid has a low viscosity.

Your steering system will eventually be damaged and cost you money if you continue to do this. Driving with a sluggish steering wheel could result in an accident. This could result in a big disaster.

How Often Should You Flush Your Power Steering Fluid?

The manufacturer provides this information. If you don’t pull or haul anything particularly big, or if your car sits for extended periods of time, the recommended interval is more than adequate.

How Much Does It Cost To Change Power Steering Fluid?

Changing the power steering fluid costs, on average, only $120. There are a variety of steering fluids recommended by different manufacturers. The pricing may be affected by this. But on average, the price is $120.

How Much Does It Cost To Fix Power Steering Assist Fault?

This is entirely dependent on the component that has been damaged in the first place. In most cases, if the problem is caused by filthy or low fluid levels, the repair costs roughly $120.

If an electrical malfunction is the root of the problem, expect to pay more. In this situation, you can anticipate to pay up to $300 for the repair of a damaged electrical component.

If your pump fails, it’s the worst-case situation. Steering fluid pumps can cost as much as $1000 for some types.


When it comes to driving safely, power steering is a must-have feature. Only the steering wheel can be used to control the vehicle. However, despite the fact that the engine and the brakes allow you to accelerate and decelerate, they cannot keep your car on the road.

When it comes to power steering, there are three categories to consider. We begin with a 1951 hydraulic steering system. A hydraulic fluid is used to transfer force from the engine to a nearby object.

The EPAS follows next. This is a battery-powered electric system. This is not uncommon when it comes to newly produced automobiles. Finally, a hybrid system is in place. An electric battery is used to power the hydraulic fluid that transfers power.

A power steering assist error can occur for a variety of reasons depending on the steering system being used. Hydraulic fluid or electrical malfunctions are the most common culprits. You have to deal with the power steering failure in accordance with the cause of the problem.

The trouble codes can be cleared simply restarting your vehicle. However, you should not disregard this caution. An issue is on the horizon, as indicated by the notice. As a result, you should have your vehicle inspected as soon as possible. Changing the code will not fix the problem.

There’s a good chance you’ll see it again soon. You risk losing your power steering if you ignore the warning light.
