How to Fix a Power Steering Assist Fault
What Is Power Steering Assist? In the middle of the 20th century, you had to force the steering wheel of a car to move in the direction you desired. Domestic autos were not equipped with power steering until 1951. Chrysler Imperial was the first vehicle to receive it.
The power steering system has gotten more sophisticated since its launch. Today, we have steering systems with electric power assistance. While it still utilises a hydraulic pump to propel fluid, it no longer absorbs the energy produced by the engine, as was the case with prior models. Instead, an electric pump is utilised to pressurise the fluid, so making steering easier.
In the reservoir, there is hydraulic fluid. As you spin the steering wheel, the fluid transfers and generates a turning force that turns the wheels. Belts are utilised to pull energy from the engine in older systems. Today’s vehicles, particularly hybrids, utilise an electric pump powered by the battery.
The significance of the power steering system stems from the fact that modern safety features rely on it. The EPAS system may play a role in the operation of your vehicle if it is equipped with parallel parking assist, lane assist, or other advanced technology.

In addition, the majority of automakers advise replenishing the power steering fluid every four years or 50,000 miles, whichever comes first. Not changing the fluid can result in contamination, diminishing its effectiveness.
2. Examine error codes
Before beginning any electrical troubleshooting on your vehicle, you should always read the error codes with an OBD2 scanner. This might provide you with very useful information so that you do not squander money.
If the power steering assist problem message shows on your dashboard, the reason the light is on is indicated by a fault code. You can either visit an auto repair shop to have the error codes read for you, or you can get your own OBD2 scanner. However, it is crucial to acquire a scanner that is compatible with the power steering assist system in your vehicle’s make and model.
If it appears to be displaying the correct information but your steering wheel is not straight at higher speeds, you may need a wheel alignment.
3. Replace Angle of Steering
Unfortunately, in some automobile models, the new steering angle sensor must be programmed, which is often done by the dealer.
If it is not the issue, it is time to move on to the electrical components of the system. If you discover frayed or damaged connectors or wiring, it is time to replace them.
5. Replace Failing Belt
However, numerous models make it difficult to replace the belt. If you are unsure of what you are doing, it is best to consult a specialist before further damage occurs.
6. Replace Steering Power Steering Pump
Consult the vehicle’s service manual to determine the necessary actions. If not, take it to a nearby auto repair shop for more assistance.
Price of Power Steering Assist Repair
Depending on the findings, the cost to repair your power steering assist problem could range from $5 to $550 or more. If you only need to add a small amount of fluid or replace a fuse, your repair costs will be inexpensive.
Repairing leaks, electrical issues, or critical components can significantly increase the cost. In addition to expensive parts and the requirement for a specialised mechanic to operate on the system, luxury vehicles are often always more expensive to repair.
If you can conduct the repairs yourself, it will be considerably simpler to limit your expenses. Nevertheless, you should never work on the hydraulic or electric power steering system if you are unsure of what you are doing. One tiny error can soon lead to larger difficulties, resulting in a skyrocketing repair price.
