There’s nothing quite like the feeling of effortlessly guiding your Polaris Sportsman 570 through tight, technical trails. That Electronic Power Steering (EPS) is a game-changer, turning a potential wrestling match with the handlebars into a smooth, enjoyable ride. But what happens when that smooth ride suddenly turns into a full-body workout? You’re not alone.
We’ve all been there. One minute you’re cruising, the next a warning light pops up, or worse, the steering goes completely stiff in the middle of a tricky climb. It’s frustrating and can quickly ruin a day on the trail. Many riders immediately fear a massive repair bill, but it doesn’t always have to be that way.
In this complete guide from FatBoysOffroad, we promise to walk you through everything you need to know. We’ll break down the most common 2017 polaris sportsman 570 power steering problems, show you how to diagnose them with basic tools, and give you the confidence to tackle these issues yourself. We’ll cover everything from simple electrical checks to understanding trouble codes, so you can get back to what matters: riding.
Recognizing the Red Flags: Common Symptoms of EPS Failure
Before you can fix the problem, you need to know what to look and feel for. Your Sportsman will usually give you a few warning signs that its power steering system is unhappy. Paying attention to these clues is the first step in your diagnostic journey.
The Dreaded Power Steering Warning Light
This is your machine’s most direct way of telling you something is wrong. An illuminated EPS warning light on your dash is an immediate call to action. It typically indicates that the EPS control module has detected an electrical fault somewhere in the system.
This could be anything from low voltage to a sensor failure. Don’t ignore it, even if the steering still feels fine. It’s the earliest indicator of potential common problems with 2017 polaris sportsman 570 power steering problems.
Intermittent Power Steering Assist
This is one of the most confusing and common symptoms. One moment the steering is light as a feather, and the next it’s stiff as a board, only to return to normal a few seconds later. This on-again, off-again behavior is almost always electrical.
It often points to a poor connection, a wire that’s rubbing somewhere, or a battery that can’t supply consistent voltage. It’s especially noticeable when turning the handlebars at low speeds or when using other high-draw accessories like a winch.
Complete Loss of Power Steering
This is the most obvious and jarring symptom. You hop on your ATV, start it up, and the handlebars feel like they’re set in concrete. The power steering is completely gone. While this could mean the EPS motor itself has failed, it can also be caused by something as simple as a blown fuse or a disconnected plug.
Unresponsive or “Notchy” Steering
Sometimes the steering doesn’t fail completely but feels strange. You might feel a “notch” or a dead spot as you turn the handlebars, or it may feel like it’s lagging behind your input. This can indicate an internal mechanical issue within the EPS unit or a problem with the sensors that tell the motor what to do.
Your First Line of Defense: The Easy DIY Checks
Before you start tearing your ATV apart and pricing out expensive components, take a deep breath. Over 50% of all electrical issues, including those with power steering, can be traced back to the basics. Grab a few tools and let’s start with the simple stuff.
Check Your Battery and Charging System
The EPS system is a power hog. It needs a steady supply of clean voltage to work correctly. A weak battery or a faulty charging system is the number one cause of intermittent power steering problems.
- Visual Inspection: Start at the battery. Are the terminals clean and tight? Look for any corrosion (white or greenish powder). Clean them with a wire brush and ensure the connections are snug.
- Voltage Check: Grab a multimeter. With the ATV off, a healthy battery should read between 12.4V and 12.8V.
- Charging System Check: Start the engine. At idle, the multimeter should now read between 13.5V and 14.5V across the battery terminals. If it’s lower, your stator or voltage regulator might be failing, starving the EPS unit of the power it needs.
Inspect the Power Steering Fuse
The next simplest check is the fuse. Your Sportsman’s fuse box is typically located under the front storage rack. Pop the cover off and look at the diagram on the underside to locate the fuse labeled “EPS” or “Power Steering.”
Pull the fuse out and hold it up to the light. If the small metal strip inside is broken, the fuse is blown. Replace it with a new fuse of the exact same amperage. If the new fuse blows immediately, you have a short circuit that needs further investigation.
The “Key Cycle” Reset Trick
Sometimes, the EPS module just has a momentary brain freeze. A temporary voltage drop or a sensor glitch can cause it to throw a code and shut down as a precaution. A simple reset can sometimes clear it.
Turn the key to the “ON” position (don’t start it), wait 5 seconds, then turn it “OFF.” Repeat this process 3-4 times. This can sometimes clear a soft code and restore power steering function. It’s not a permanent fix, but it’s a great troubleshooting step.
Diving Deeper: A Step-by-Step 2017 polaris sportsman 570 power steering problems Guide
If the easy checks didn’t solve your issue, it’s time to dig a little deeper. This section will guide you through inspecting the system’s wiring and understanding what your ATV is trying to tell you through its diagnostic codes. This is how to 2017 polaris sportsman 570 power steering problems are truly diagnosed.
Inspecting the EPS Wiring Harness and Connectors
The wiring harness for the EPS unit lives a tough life, exposed to mud, water, and vibration. You’ll need to remove the front plastics and possibly the front storage rack to get good access.
Look for the main connectors going to the EPS unit, which is mounted to the steering column. Unplug them and inspect the pins inside. Look for any signs of green corrosion, dirt, or moisture. Clean them out with electrical contact cleaner and a small brush. Before plugging them back in, apply a small amount of dielectric grease to the seal to keep moisture out in the future.
Carefully trace the wires as best you can, looking for any spots where the loom might be pinched, chafed, or melted against the exhaust. A single damaged wire can take down the whole system.
Understanding Diagnostic Trouble Codes (DTCs)
When your EPS light is on, the computer has stored a code that points you toward the problem. You can often read these codes right from your instrument cluster without a special scanner.
The procedure can vary slightly, but it often involves cycling the key or pressing the override button in a specific sequence. Consult your owner’s manual for the exact steps. Some common EPS codes you might see include:
- Code 520207 & 520208: These often relate to low system voltage or an inconsistent power supply. Go back and double-check your battery and charging system!
- Code 520230 & 520231: These can indicate a fault with the EPS control module itself or a loss of communication.
- Code 61: This is a common one indicating a steering torque sensor failure, which is internal to the EPS unit.
These codes are your roadmap. They tell you where to focus your attention instead of just guessing.
When the Fix is a Replacement: Sourcing and Installing a New EPS Unit
After thorough testing, you may come to the conclusion that the EPS unit itself has failed internally. This is the most expensive scenario, but it’s a manageable DIY job for a weekend mechanic with the right tools and a bit of patience.
OEM vs. Aftermarket: Making the Right Choice
You have two main options for a replacement unit. You can go with an OEM (Original Equipment Manufacturer) part from Polaris, which guarantees a perfect fit but comes with a hefty price tag. Or, you can explore aftermarket options from companies like SuperATV, which often offer robust, well-regarded units at a more competitive price.
Do your research, read reviews from other Sportsman owners, and choose the option that best fits your budget and needs. The benefits of 2017 polaris sportsman 570 power steering problems being solved with a quality part are long-term reliability and peace of mind.
Basic Steps for EPS Unit Replacement (A High-Level Overview)
Replacing the unit is an involved process. We strongly recommend you get a copy of the official service manual for your 2017 Sportsman 570 before you begin. However, the general steps are as follows:
- Safety First: Disconnect the negative battery terminal.
- Gain Access: Remove the front wheels, front plastics, and front storage rack.
- Disconnect Steering: Remove the tie rod ends from the steering knuckles. Unbolt the upper and lower steering shaft connections from the EPS unit.
- Remove the Unit: Unplug the electrical connectors and unbolt the EPS unit from the frame.
- Install New Unit: Installation is the reverse of removal. Bolt the new unit in, reconnect the steering shafts, and plug in the electrical connections.
- Final Assembly: Re-attach tie rod ends, reinstall plastics and wheels. Reconnect the battery.
Take your time, take pictures as you go, and make sure every bolt is torqued to spec. An alignment is highly recommended after this job.
Proactive Care and Best Practices for a Healthy Power Steering System
An ounce of prevention is worth a pound of cure. Following a few 2017 polaris sportsman 570 power steering problems best practices can help you avoid these issues in the first place and extend the life of your components. This is your essential care guide.
The Importance of a Strong Electrical System
We can’t stress this enough: keep your battery healthy. If you don’t ride often, use a quality battery tender to keep it topped off. A strong battery is the foundation of a reliable EPS system.
