Power steering kits are fairly complicated pieces of equipment, and our EZ STEER Power Steering Kits are no exception. They’re designed to perfectly translate your steering wheel movements to powered rack movements on the fly. All the while they have to counteract every bump and rut you hit on the trail.
All those moving parts working together mean that sometimes something can go wrong. Whether it’s hard to turn immediately following installation or it stops working years later, we’ve compiled our troubleshooting guide to help figure out your power steering problems. Follow these steps, and you can get your power steering kit running like new again.
These are the most common mistakes we see when someone calls in with a power steering problem:
Most likely, your issue is one of these four. We’ll walk through these issues and a few other less common issues that you can check for before giving customer service a call.
If your white activation wire isn’t connected properly, you’ll have power steering problems. In fact, your kit won’t function at all. This wire should be hot when your key is turned on.
First, you’ll want to make sure the connection between the white wire and your keyed-on power source is solid. A faulty connection can cause intermittent power loss.
If you’re unsure of where your keyed-on power source is located, look for your vehicle’s busbar or power bar. Here’s a list of busbar locations for various makes and models:
Some vehicles don’t have a busbar. Here’s where you can find a keyed-on power source for those UTVs:
Checking your connections is a straightforward process. First, unplug all connectors to the ECU, wait a few minutes, and plug them back in while making sure they’re fully seated. You should feel a click when they’re pushed in all the way. If you don’t, check for bent or broken pins that can interfere with the plug.
To check the ECU voltage output, touch the hot and ground in the plug running to the motor, turn the machine on, and then turn the wheel.
Your multimeter should be on the voltage setting (v) and you should read 3.0 to 6.0 volts going through the two wires. If it’s in the range of 2.0-7.0 volts, you’re good. If it is out of that range, the ECU may be bad.
When checking resistance on the motor, make sure the leads from the motor to the ECU are disconnected and the vehicle’s key is in the off position.
Set your multimeter to the OHM’s setting. Then, check the motor’s ohm reading across the two lead plugs going to the motor. This reading is important and should be checked at least three consecutive times to ensure accuracy.
Results should be between 0.0 to 1.2 ohms. If the ohms are higher, the motor may be bad.
The torque sensor is the brains of your power steering unit. If it’s out of whack, you’ll have power steering problems. Here’s how to check the torque sensor.
After checking the torque sensor, plug it back into the ECU and back-probe the plug. This time, check the voltage from the white and black wires to the ground (green wire). You can also ground your probe on the chassis.
Results should be around 2.0 to 2.5 volts on each wire.
Now, you’ll check to make sure the torque sensor functions properly while in use.
If you’re outside that range, give us a call.
When an EZ STEER power steering unit is installed on an ATV, it has looser steering than when it didn’t have power steering. This is completely normal.
Also, ATVs use the blue speed sensor wire. This will take away some of the voltage to the power steering unit as the speed increases to reduce the chance of over steering or over correction.
If you found a problem with your wiring, plugs, ECU power, or torque sensor that you can’t fix, what are you supposed to do now? Give us a call at 855-274-3427. Our technical support team is available Monday-Friday 8:00 AM to 5:00 PM ET and Saturday 9:00 AM to 2:00PM ET to answer any questions. They can help you with the next steps of troubleshooting so you can quit thinking about your parts and start thinking about your next ride.

Would it be ok to run little white wire to my fuse box.
Hey Richard! You can run it to the fuse box as long as you connect it to a key-on wire or fuse. Thanks for checking in with us!
I have had the EZ power steering fitted to my MGB GT V8 and whilst it works well as an aid to heavy steering at low speed the steering no longer self centres. The fitter tells me this is normal but I have my doubts as it makes the car a little twitchy at speed and the wheel has to be held quite firmly at all times. Is this Normal or is something not quite right as i suspect. Help required
Hey Michael, if I’m understanding correctly, you feel it’s touchy at high speeds. The universal kit has the transmission speed sensor, but you would have to figure out where that wire would need to go. It should not self center. Feel free to give us a call at 855-743-3427 for any help!
I’m fitting this superatv power steering to my Formula 500, where do I attach the white activation wire
Hey Diane! You should be able to attach this wire to any key-on power source. Thanks for reading!
I used your 600 watt universal power steering unit on a custom harley reverse trike. It works as far as making it easy to turn. My problem is the play in the unit. I don’t see any way to remove it. I will end up removing it. That might be why some people talk about it being twitchy. By the time I could catch the steering on the other side, it would cause me to over correct.
I’m trying to get a hold of superatv for my power steering problem on my Polaris ranger. It stop working n I did all the test to diagnose it and everything came back good but the system is still not working need help the number is disconnected to talk to any representative all the ohms and the testing came back properly the light blinks on and off when I unplug the motor when I plug the motor in a blinks once and shuts off does not blink againA phone number to talk to a representative would be nice to get some better results thanks again been a customer for 8 to 10 years now
Hey CJ! I’m sorry for the trouble. Shoot an email over to our warranty department and we can try to get you squared away. You’ll need to make sure you have your order number available, and let them know the details of the trouble you’re having. It’s warranty@superatv.com. We’ll be glad to help get things taken care of for you. Thank you for the continued support!
Can i jump the motor somehow to see if it works and if so how?
Thanks for tuning in with us! Check out the section labeled “Checking OHMs on the Motor” for instruction on this.
I have super atv power steering on a 07 rhino steering is strong you can turn all the way right whip it to left it will keep turning with no contact on wheel till it is turned full right
Just finished installing the 400w universal unit in my 1952 Chevy sedan, must say it’s amazing how smooth this unit works ! Made the frame brackets and u joints to the rack and pinion and steering column. The installation was a good 12 hr. Job but will worth the time and money investment. I had previously installed a after market front end assy, with a manual rack and was way hard to turn when standing still with this unit it is a pleasure to drive now. I highly recommend this addition.
That’s awesome to hear. Thanks for the support and feedback, Bill!
hi last august i got your kit for a 2019 polaris sportsman 850 was working very good and then i heard a bussing noise from the power steering and then it stop but still out and i get 5v on the green and orange wires!!!!
Hey Daniel. It could be a few different things. It could be caused by your Sportsman’s battery if it’s dying and outputting less than 12.8 V on the white, key-on wire while the power is on without the engine running. Or the solenoid could have gone bad. The good news is that if you bought it last year, you should still be covered by our warranty. If you can’t get it working again, give us a call: 855-743-3427. Thanks for reading!
batt. ok at 12.7 when this happend at first i could hear a buzzing noise from the power steering for 20 sec. about as soon as i would put the ing. on and on the 4 wires i get 5v on the green and orange but nothing on the white and black!!!!!!
12.7 V is borderline, so that could be your issue. It really wants 12.8 or more. Make sure you don’t have any other accessories drawing too much power, like hand warmers (even if they’re off, they can eat up too much voltage). If you can, try checking it with a newer battery and see if it works then. If it does work with a newer battery, then you just need to replace your battery. If it doesn’t work with a newer battery, then it’s your ECU, and you need to give us a call at 855-743-3427 to get it replaced.
I have this system on a CFMoto CF500AU and EPS has an error code 32
just following your checks as no other info out there on these chinese ATVs
i have power in to ECU but no power to motor, i pulled motor out and works connected to battery
torque sensor shows 5 volts when plugged in but nothing unpluged as per you instructions, also the white / black to ground ok
and 0-4.0 when trying to turn steering ok
thinking ECU is bad
Hey Paul, your white key-on wire should get a minimum of 12.8 V with the key on, but not the ignition. If you’re not getting 12.8, it could indicate either a bad ECU or a dying battery. If you’re saying that your CFMoto’s battery is good, then it’s mostly likely the ECU.
You can give us a call at 855-743-3427, and we can help you out. EZ Steer carries 3-year warranty, so hopefully we can get you up and running without too much trouble.
I have an EZ Steer system on a JD Gator 825i that is not working. It was installed prior to my purchase. The red indicator light is flashing 2 longer lights followed by a slight pause and then a short flash. All the connections seem to be good and the battery is new. Any suggestions for diagnosis? Thank you.
Hey Rick. That error points to the torque sensor, which is part of the motor. Either the torque sensor itself is bad, or the ECU isn’t communicating with the torque sensor properly. The best case scenario would be a loose connection between the motor and the ECU. Follow the steps above under the “Checking Your Torque Sensor” section. Odds are you’ll need to replace either your ECU or motor. Give us a call with your results at 855-743-3427 and we can get you taken care of.
Good afternoon
We have the ez steer system on our micro sprint. The problem we are having is that it randomly shuts off while racing. If you cycle the toggle switch From off to on it will start working again. Another car owner with the same system on their Micro Sprint said they have had the same issue. Any suggestions?
Hey Matt. Sorry for the delay getting back to you. Micro sprints usually lack the charging system that side by sides have, so the power steering ends up shutting off after the battery gets to an insufficient voltage. The thing most people do is install a switch so they can power the system right before a race and shut it off right after.
Hopefully that helps!
Hi , I have a 2013 can am maverick that I have had the electronic power steering on. When turning you can notice one side turns further than the other. And while driving down the road it drifts left and right finding yourself constantly chasing the steering. When jacked up you can push on either wheel and it will turn about 3” before the other one begins to turn with the other. It’s the same from both sides.
Hey Chad, that doesn’t sound like a power steering problem. Even if the motor were going bad or had a lot of slop, you wouldn’t be able to push one wheel 3″ before the other starts moving. It sounds like your alignment’s off and you’ve probably got some parts wearing out. Check your bushings, wheel bearings, tie rod ends, and your rack. Any or all of those could be causing all that play. Hopefully you get it sorted out. Thanks for reading!
new install binds and motor mount bounces in two positions when turning wheels.
guidance please.
Hey Steve, loosen up everything and realign your shaft and motor. Get everything lined up perfectly and then tighten it down. That should get you riding smooth. Thanks for the question!
I have a 2014 Can-Am Maverick Max 1000 r I recently washed it and after that my power steering stopped working. I went through all the Diagnostics and found the red and black wire coming from the torque sensor is reading zero. Can I just replace the torque sensor or do you have anything else I should diagnose first?
Hey Brandon, you can’t replace the torque sensor alone, unfortunately. You’d have to replace the whole motor. But usually, when a torque sensor alone goes bad, your wheels automatically move all the way to the left or right. So you could have a bad motor on your hands, but that almost never happens. Give us a call at 855-743-3427 so we can go over your issue in more detail to make sure we get you fixed up the right way.
Hello SuperATV,
I am looking for EZsteer kit for 2005 Polaris Sportsman 400. Which kit will fit my ATV?
Hey Rob, we don’t have an EZ-STEER kit for your Sportsman unfortunately. If you don’t mind doing a little welding, you can get our universal kit (https://www.superatv.com/universal-power-steering-kit-380w) installed pretty easily. It’s a pretty popular choice for folks who can’t otherwise find a kit for their machine.
question..power steering quit working. checked all we could and find it is probably the sensor on the motor. can i replace the sensor by taking it off and not replace the whole motor.
Hey Steve. You can’t replace the torque sensor separately from the motor unfortunately. Give us a call at 855-743-3427, and we’ll see what we can do to get you running again.
Just finished installing EZ-Steer on my 2015 RZR 900S. Unit appears to work but turning left is very limited, turning right seems ok. What have I done wrong and easiest way to fix?
Hey Pat. That’s weird that it’s one-sided like that. If you mean that you’re turning radius when turning left is limited, the you need to redo the steps to center your rack. If you mean that there’s little to no assist when turning left, then you need to give us a call at 855-743-3427 so we can get you sorted out.
Just installed the EZ steer. The power steering unit is working, but my indicator light is off the question I have is the indicator light needs to be on or does it come on when there’s something wrong.
Hi, Mike! Our EZ Steer kit is a stand-alone unit. It doesn’t speak with the stock ECU. The ECU is no longer finding the stock EPS so the indicator light is always going to be off. The only way to change that is to flash the ECU to make it forget about the stock unit. Totally normal.
do they have a power steering kit for a 2021 hisun 550 eps
Hi Keith! We don’t have a specific kit for the Hisun, but we do have 3 options for universal power steering kits that may work for you. Check them out here: https://www.superatv.com/search/?q=universal#/filter:product_category:Power$2520Steering
My installation works fine, but the steering wheel light with the exclamation point beside is on and I can’t get it to turn off. I’ve done the steering initialization, toe check and centered the wheel. Any suggestions?
Hey Lou, unfortunately there’s no way to make that light turn off since our power steering unit bypasses the ECU. Some people put a piece of electrical tape over it so they can forget about it. It’s not ideal but hopefully that helps. Thanks for the question!
What size fuse is used on the 220 watt system?
Hi Brian. There are multiple 220-watt EPS kits. Do you have one you’re looking for specifically? I’m not certain all the fuses are the same across units, so I want to be specific.
I installed the 220-watt EPS kit on a Honda Pioneer 500, works excellent but I noticed that there is a lot of up/down flex on the upper mounting bracket.
Hi Edgar—Glad to hear you’re enjoying the EPS kit. Some flex isn’t unusual. We don’t want the brackets to be too rigid, because that puts them at higher risk of breaking under stress. If you’re concerned that you might be seeing too much flexing, don’t hesitate to contact customer service to troubleshoot with you.

Hi! I have a PS-P-SPT-380 kit on a Sportsman 570 2018 model. The EPS works very well, but the steering is too sensitive at higher speeds and driving may even be dangerous. I connected the VSS signal from the sensor to the EPS as instructed.
How can I check, e.g. with a multimeter or other means, if the EPS is receiving the VSS signal from the ATV correctly? The speedometer on the ATV is reading correctly and there is no problem with its operation.
Thanks for reading!

I tried calling your number and I cannot get through. I have a bad ECU according to your test.
Hi Jimmy, sorry you’re having trouble. Make sure you’re calling 855.743.3427. If you still can’t get through for some reason, you can text 318.666.3419 or email sales@superatv.com.
So with the above troubleshooting guide, on the ECU Voltage Output, I am getting 9.6V, which is out of range. On the torque sensor, I am getting 5V out of the red wire and around 2.5 V on each of the white and black wires, BUT when I turn the wheel all the way in either direction, my range is between 2V and 3V and not 1V and 4V.
Any thoughts on whether this is a major issue? My steering wheel is very loose with the PS on and wondered if this has to do with the additional voltage above the top end 7V?
On another note, because the speed sensor option is not available for me, if I wanted to create a manual speed setting with a potentiometer (0V to 5V), which wire would need to be connected to the 5V signal to create the same effect as the VSS?

21 rzr xp 300 miles torque sensor damaged due to electrical overload on winch does your easy steer plug and play without changing all components or does all steering sections down to rack replace?
Hey Rick,
You would replace the steering shafts, motor, and ECU module! There’s no need to worry about your rack.
On another note, because the speed sensor option is not available for me, if I wanted to create a manual speed setting with a potentiometer (0V to 5V), which wire would need to be connected to the 5V signal to create the same effect as the VSS?
I have same question that Jordan has but i dont have option to call can you reply to my email
Hey Roope,
Here is our email to reach out to a technician. sales@superatv.com
I have the 220 W on my Honda ATV ever since I installed it(immediately) there was slop in the steering (handle bars) of over a 1 1/4″ either turning to the left or right. All tie rods, ball joints, steering stem are tight. Any ideas why? Unit works perfectly, but I don’t like this slop. you end up over compensating. You can visually see the top shaft on the motor turn that distance, while the bottom shaft doesn’t move at all.
Hey Earl,

What happens if the motor is installed upside down I.E. the torque sensor is facing down? not up
Hey Earl,
We don’t recommend installing it upside down—it would fight against itself to turn. This could lead to damage.
I double checked my install and its installed according to the directions. The handle bars move approx. a 11/4 to 1 /12 before the front wheels begin to move. Every ball joint tie rod ends etc. have been changed. So again why is there so much play and is there anything to correct it?
Hey Earl,
A technician can assist you if you give us a call! 812.574.7777
I have this system in a CF Moto 600, and the power steering has just failed. The steering only works turning right, and as soon as I try to turn left, the dash flashes a code 32. Motor resistasnce is 0.7ohms, The torque sensor output has 5v, and then 2.5 on each leg. When turning the range is 0.8v to 4v. That all seems normal.
Where I think there is a problem, is that when I probe the ECU voltage output to the motor, I get a surge of up to 14v before it goes to 0.
Is the ECU bad?
Hey Mark,
Unfortunately, you’re going to have to replace your ECU! Give us a call and we can help you out.

Give us a call for more assistance! 812.574.7777
Hello
Thank you for reply but the problem is that I am based în Europe, so could you provide a whatsapp number to contact you?
Hi Madalin,
Unfortunately, we don’t have a Whatsapp number. Can you confirm that the machine is charging when it is running? If not, it will run a low voltage to the EPS and cause it to work intermittently. If it is charging, disconnect all connections and reconnect them. Do you have an email where I can send you a troubleshooting guide?
The charging in on point,between 13.8 and 14.2 v. On the red and black wires that goes from the EPS to the motor, with the engine running, I have the same voltage as the battery, sometimes it works for about 2 or 3 cycles left-right, othertimes it works only one turn from center to full left.
