Electrical power steering systems use no fluid, so a top off is not an issue when the warning light comes on. In most cases, a simple technical glitch in the computer system may be the culprit, so a simple reboot is in order. All you need to do is turn off your engine, then restart it so the light can reset.
It is never advisable to drive once the power steering warning sign pops up on your dashboard. The best you can do is perform the diagnostics yourself if the problem is minor and check on your mechanic immediately. The steering system is the most critical part of your vehicle because it helps guide your car.
The light warns you that the power steering system has failed and prompts you to investigate for a cause. The cause may vary according to the type of power steering system in your car. In hydraulic power steering systems, a leak in the system causing a low fluid level is the most common cause for this problem.
This warning light can indicate malfunctions in your power steering system or low power steering fluid. The light looks like a steering wheel with an exclamation point to its right.
The EPS light comes on when the computer detects an issue with the vehicle`s electronic power steering system. If the computer detects an issue with the system it will set off the warning light to notify the driver of… Your vehicle is equipped with electronic power steering (EPS).
Answered by CarsGuide. The power steering is an electrical system, so a problem with the battery could affect the power assistance. You should still be able to steer the car even without power assistance. It won`t affect the braking.
How much should I expect to pay? While the price of this repair can vary, expect to pay between $500 and $800 to get your power steering pump replaced. Depending on your car, the cost could exceed that price, or fall below it.
The electric power steering system (EPS) Warning Light is located on the instrument panel. When the light is illuminated, it means that the EPS system is not functioning properly, and the vehicle should be serviced. Tip Like all warning lights, the EPS warning light briefly illuminates when the car is turned on.
Malfunction Indicator Light

This dashboard light comes on steady or blinks when there`s a potential emission control malfunction. However, it can also detect when your fuel filler cap is loose or missing or if you`re running low on fuel.

Electric Power Steering (EPS) is virtually maintenance-free. There is some system that still uses 2 phase DC motors with brushes. Ultimately they wear and need replacing. The EPS needs careful calibration when it comes to its steering angle and or torque sensor.
This issue with the EPS light can also be caused if you have recently had to jump-start your car, or you`ve disconnected the battery. Occasionally, the problem can be fixed by simply turning your vehicle off and on again.
EPS is a relatively simple system. The steering shaft torque sensor, located in a section of torsion bar in between the steering input and output shafts, is the PSCM`s main input for determining steering direction and the amount of assist needed.
While it is technically possible to drive the car with a failing electric power steering system, it is not going to get any better. The vehicle will need to be serviced as soon as possible. The module is still pulling excess power from the battery and robbing the rest of the vehicle.
Electronic failure is when the electrical systems keeping the power steering running stop functioning. This type of failure can be caused by a fuse issue, so you can easily check the fuse box to see if one of the fuses needs replacing.
Now, when it comes to the power steering system, if the alternator fails to supply the vehicle with electrical power, the power steering pump will fail, and you will lose hydraulic pressure needed for assisting in steering. You will also lose many other systems in the vehicle.
The average cost for a Power Steering Control Module Replacement is between $900 and $929. Labor costs are estimated between $108 and $137 while parts are priced between $792 and $792.
How often does a power steering pump need to be replaced? Most vehicle`s power steering system will last for 100,000 to 150,000 miles before a pump replacement is warranted.
Diagnostics on any EPS system should begin by scanning the EPS module for diagnostic trouble codes. For example, a “C-series” code indicates problems within the feedback and electromechanical assist portions of the system.
Today`s electronic power steering systems may fail due to issues with the mounted electric motor. In particular, excessive heat on the motor is likely to cause the failure modes. Infiltration of the system environment by water, dirt, or other contaminants will also likely lead to EPS failure.
Electronic power steering systems (EPS) are now more common than ever on newer Nissan vehicles.
Electric power steering systems are simple. Hydraulic power steering systems tend to be heavier than electrical systems. Hydraulic power steering systems require hydraulic fluid, which must be changed from time to time. Electrical systems don`t use any fluid, so you don`t have to do as much maintenance.
One of the most common problems power steering systems have is leaks. The high pressure of the system combined with the soft hoses carrying the fluid makes it relatively susceptible to leaks. A low fluid level can cause a whining power steering pump and even a loss of fluid pressure and a loss of steering assistance.
Just as important, the fluid attracts moisture, and since moisture/water has different (less effective) properties than steering fluid, with time the fluid delivers decreased power through the system. On top of that, water is corrosive and can damage steering components over time.

2012 equinox reduced power light engine light and traction light came on. Lost a lot of power got home and all light except engine
ANSWER : Your car has what is called a "safe mode" that will be engaged by the computer when it detects that something critical has gone wrong related to any of the major components in your engine chassis or power train. This may be related to a number of things, most of which should have been registered in the computer when the check engine light came on. I recommend having an expert from YourMechanic come to your location to inspect your check engine light and diagnose any codes registered by your vehicle’s computer.

Steering wheel shakes, light came on power steering assist failure 2010 Ford Escape
ANSWER : Hi there – this behavior, sometimes called "phantom steering shake" is often due to a steering torque sensor in the steering column. This device sense how much effort is being put into the steering wheel to make a turn. This determines how much "power assist" the electronic steering adds to your own effort to turn the steering wheel. If you are getting the "shake" while idling and still, this can be the beginnings of failure of this sensor. I would first go back to Ford to discuss the Recall (#14V284000), because this appears to be precisely the problem you are having. Escalate to Ford Customer Service. If this is unsuccessful, I recommend a steering wheel shakes inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, confirm this diagnosis, and give you an accurate assessment of damage and cost estimate for repairs.

The electric power steering system warning light is on and check engine light is on and don’t turn on
ANSWER : Hello, thank you for writing in. The vehicle is having obvious issues with the power steering system. When the problem is detected while the computer runs scans as it starts, and the problem is bad enough, the system will not allow the vehicle to start or be driven. With that being said, the issues detected by the computer can be read with a scan tool. Once you have these codes, you can use them to help you narrow in on the exact issue. You can take corrective action from there. Unfortunately without these codes, it is a guessing game to figure out what the issue may be. Typically this would require a tow to the shop, however you do have access to our mobile technicians through our service department.

I had a warning message in my 2013 Ford Fusion that the power steering assist failed. I have power steering capability now. Is it safe to drive?
ANSWER : Some 2013 Ford Fusion models are part of a safety recall involving loss of steering assist. Contact your dealer with the Vehicle Identification Number (VIN) or check your VIN number on safercar.gov to verify if this recall applies to your vehicle. Loss of steering assist can be dangerous if you are caught off guard. It would be best to not drive the vehicle. Contact your dealer to have it towed to their location.

3 warning lights on, power steering, VMS, and electronic lights. Any clue?
ANSWER : The fact that these lights are on is a warning to the driver that there are fault codes stored because one of more control systems have detected a problem. The vehicle will have to be read with a code scanner to retrieve the codes and move on with the diagnosis from there. The problem can be as simple as a blown fuse, however something caused the fused to blow so that will need to be tracked down. I do not have your model of Honda so it will be a little difficult to offer suggestions. Consider hiring an experienced technician like one from YourMechanic who can come out for a closer look at the warning lights and offer a more personal diagnosis.

Abs light, emergency brake light, steering wheel assist light, engine light, EPC light, traction control light
ANSWER : Hello, thank you for writing in. The vehicle does utilize a lot of the same sensors for these systems. Are there any other codes that are coming up when this code appears? If so you will want to take these into consideration when processing the repair and making a diagnosis. The module may be bad, and replacing it should fix the problem. The lights should turn off once the main computer recognizes the new module and the sensors sync up. If you believe the sensors need to be cleaned you may do so. Do as minimal as possible to make sure you are not damaging the sensor or disrupting the wiring inside. A bad connection would make the lights stay on. With so many lights that are effected by the module being illuminated, the module is likely bad or does not have a connection. Check the connection first and then resort to replacing the unit.
