There’s nothing quite like the feeling of gearing up for a ride, only to be greeted by that pesky check engine light glowing on your 2014 Polaris 570’s dash. It’s a frustrating moment that can stop a great day on the trails before it even starts.
You’ve probably heard you can just “clear the code” and get back to it. While that’s sometimes true, doing it wrong can hide a serious problem or even make things worse. You need a reliable, safe way to handle it.
In this guide, we promise to walk you through the entire process. We’ll show you not just how to clearing codes on 2014 polaris 570, but more importantly, why you’re doing it, when it’s safe, and what those codes are really trying to tell you. We’ll cover the simple tricks, the reliable methods, and the best practices to keep your rig running strong.
First Things First: Why Are You Even Seeing a Code?
Before you even think about clearing a code, you need to understand what it is. That light on your dash is your Polaris’s way of talking to you. It’s connected to the Engine Control Unit (ECU), the onboard computer that monitors dozens of sensors.
When a sensor reading goes outside its normal range—even for a split second—the ECU logs a Diagnostic Trouble Code (DTC). This code is a specific message pointing you toward the problem area.
Common triggers on a 2014 Polaris 570 can be surprisingly simple. It could be a loose gas cap, a bit of water in a connector after a creek crossing, or a momentary voltage drop from a weak battery. Of course, it can also signal more serious issues like a failing oxygen sensor or a throttle body problem. The code is your first clue in solving the mystery.
The Critical Difference: Clearing vs. Fixing
This is the most important lesson you’ll learn today. Clearing a code is not the same as fixing a problem. Think of it like this: turning off a fire alarm doesn’t put out the fire. It just makes you feel better until you see the smoke.
Clearing a code without understanding its cause is one of the most common problems with clearing codes on 2014 polaris 570. If there’s a real mechanical or electrical issue, the code will simply come right back, and you’ll have wasted your time while potentially letting a small issue turn into a major repair.
Following clearing codes on 2014 polaris 570 best practices means you always treat the code as a symptom. Your job is to diagnose and fix the root cause first. Only then should you clear the code to confirm your repair was successful.
How to Clearing Codes on 2014 Polaris 570: The Step-by-Step Guide
Alright, let’s get to the nuts and bolts. You’ve investigated the potential issue, maybe tightened a connection or replaced a sensor, and now you’re ready to reset the ECU. Here are the three primary methods, from simplest to most advanced.
Method 1: The “Key On, Key Off” Reset (The Rider’s Trick)
This simple procedure can sometimes clear intermittent or “soft” codes that were triggered by a temporary glitch. It doesn’t always work, but it costs nothing and takes 30 seconds, so it’s always worth a shot first.
Insert your key into the ignition, but do not start the engine.
Turn the key to the “ON” position. Watch the instrument cluster light up and the check engine light cycle on and then off.
As soon as the check engine light goes out, turn the key to the “OFF” position.
Repeat this process three to four times in a row without starting the engine.
On the final cycle, go ahead and start the engine. If the code was a temporary fault, the light should stay off.
Method 2: The Battery Disconnect (The Old-School Reset)
This is a more forceful way to reset the ECU. By cutting all power, you force the computer’s temporary memory to wipe clean, taking the stored codes with it. Safety is paramount here.
Make sure your Polaris is turned off and the key is out of the ignition.
Locate your battery. You’ll need a wrench (usually 10mm) to loosen the terminal nuts.
ALWAYS disconnect the NEGATIVE (-) terminal first. This is the black cable. Loosen the nut and wiggle the cable clamp off the battery post. Tuck it to the side so it can’t accidentally touch the post again.
Wait for at least 15-20 minutes. This gives the capacitors in the ECU time to fully discharge, ensuring the memory is cleared.
Reconnect the battery. This time, connect the POSITIVE (+) terminal first (the red one), followed by the NEGATIVE (-) terminal last.
Ensure the clamps are tight. Start your engine and check if the light has cleared.
Method 3: Using a Diagnostic Scanner (The Professional Method)
While most ATVs don’t have the standard OBD-II port you’d find in a car, many dedicated powersports diagnostic scanners are available. Tools like the a
This is, by far, the best method because it allows you to read the specific code first. Knowing the exact DTC (e.g., “P0122 – Throttle Position Sensor Low Voltage”) tells you exactly where to start looking for the problem. After you perform the repair, the scanner can then be used to clear the code with the push of a button.
Benefits of Clearing Codes on 2014 Polaris 570 (When Done Right)
When you follow the “diagnose first” rule, clearing the code becomes a powerful part of your maintenance routine. This is where the real benefits of clearing codes on 2014 polaris 570 come into play.
Confirming a Successful Repair
This is the number one reason to clear a code. After you replace a sensor or fix a wire, clearing the code and driving your Polaris is the ultimate test. If the light stays off after a good ride, you can be confident you’ve fixed the problem.
Resetting the ECU for a Fresh Start
After installing a new component like an oxygen sensor or fuel injector, clearing the codes resets the ECU’s learned fuel trims and other adaptive settings. This allows the computer to start fresh and learn the behavior of the new part, ensuring optimal performance.
Eliminating “Ghost” Codes
Sometimes a code gets logged due to a one-time event, like trying to start the machine with a nearly dead battery. The issue is gone, but the code remains. In this case, clearing the code is perfectly acceptable maintenance to get rid of the annoying light on your dash.
Common Problems and Mistakes to Avoid
Being a good DIY mechanic means knowing what not to do. This simple clearing codes on 2014 polaris 570 care guide can save you from big headaches.
Ignoring the Root Cause
We can’t say it enough. Never, ever just clear a code and hope it goes away for good. You’re ignoring a warning sign. That small sensor issue today could become a catastrophic engine failure tomorrow if left unchecked.
Improper Battery Disconnection
Always disconnect the negative terminal first and reconnect it last. Accidentally touching your wrench from the positive terminal to the frame while the negative is still connected will create a big, dangerous spark and can fry sensitive electronics.
Assuming the Code is Gone Forever
After clearing a code, take your 570 for a proper test ride. Some codes only appear under specific conditions (e.g., at a certain RPM or temperature). A short idle in the garage might not be enough to trigger the code again, giving you a false sense of security.
Sustainable and Eco-Friendly Practices for Your Polaris
You might not think about it, but your approach to maintenance has a broader impact. A discussion about a sustainable clearing codes on 2014 polaris 570 process is really about long-term vehicle health.
By diagnosing and properly fixing the root cause of a code, you ensure your machine lasts longer. This reduces waste and the need for major replacement parts down the road. That’s sustainability in action.
Furthermore, many codes are directly related to engine performance and emissions. A faulty O2 sensor or MAP sensor can cause your Polaris to run rich, burning more fuel and producing more pollution. Adopting an eco-friendly clearing codes on 2014 polaris 570 mindset means you’re not just turning off a light; you’re restoring your engine to its most efficient, clean-burning state.
Frequently Asked Questions About Clearing Codes on a 2014 Polaris 570
What tools do I absolutely need?
For the simplest methods, you just need your hands and your key. For the battery disconnect method, a basic socket or wrench set (usually with a 10mm socket) is all you need. A dedicated powersports code reader is a highly recommended investment for any serious DIYer.
Will clearing the codes void my warranty?
Simply clearing a code using the methods described here will not void your warranty. However, if you clear a code to hide a problem and that problem later causes a major failure, a dealer may deny a warranty claim. Honesty is the best policy; if your machine is under warranty, it’s often best to let the dealer diagnose it.
The code came back immediately after I cleared it. What now?
This is a clear sign that you have a “hard fault”—a persistent, active problem. The sensor is still reading out of range, or the circuit is still open. This means your initial diagnosis or repair was not successful, and you need to go back and re-investigate the root cause. The problem is not fixed.
Can I ride my Polaris with the check engine light on?
It depends. If the light is steady and the machine seems to be running normally, it’s likely a less critical issue (like an emissions sensor). You can probably ride it carefully back to the truck or garage. If the light is flashing or the engine is running poorly, sputtering, or making strange noises, stop immediately. A flashing light often indicates a severe misfire that can quickly destroy your engine or catalytic converter.
Mastering the art of clearing codes on your Polaris 570 is about more than just turning off a light. It’s about understanding your machine, taking a methodical approach to troubleshooting, and respecting the complex systems that keep it running. Remember to diagnose first, repair completely, and then clear the code to verify your work.
Now you’ve got the knowledge. Get back in the garage, tackle that code with confidence, and we’ll see you out on the trail. Ride smart, and ride safe!
