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.
