There it is—the dreaded orange Polaris General check engine light. Don’t panic just yet! Not all codes are a disaster. Sometimes it can be something as simple as a loose gas cap!

With this handy guide, you can figure out your Polaris General check engine codes and resolve them for good.

How to Locate the Codes on Your Polaris General

Accessing diagnostic codes for each model and year can vary. Be sure to check your machine’s manual for specific instructions.

To locate the check engine codes on a Polaris General, follow these steps:

Using the Display:

Turn the Key to “ON” Position without starting the engine
Access the Diagnostic Screen
- Press the “Mode” or “Toggle” button on the digital display until you reach DIAGCODE, CK ENG, or Engine Error Codes.
  - Some models may require you to press and hold the MODE button to open the diagnostics code menu.
- More than one code may be present at a time. Press the UP button to see if more codes are present.
View the Error Code
1. You’ll see three numbers
  1. First number (far left): This number can range from 0 to 9. This represents the total number of diagnostic codes present.
  2. The second number (top right): This number can be 2 to 6 digits in length. This number is the SPN, or Suspected Area of Fault
  3. The third number (bottom right): This number can be 1 to 2 digits in length. This number is the FMI, or Fault Mode
Record the numbers
1. Write down the numbers you see and compare to your owner’s manual or our definition table at the end of the article

Blink Code Method (Older Models without a Digital Display):

The Polaris General has had a digital display since 2017, when Polaris launched the Ride Command System on the machine. If you have a 2015/16 General or different older Polaris model without a digital display, you’ll use the blink code method below.

Again, different models may use different methods. Check your machine’s manual for specific instructions.

Cycle the Key
- Turn the ignition key ON-OFF-ON-OFF-ON quickly, leaving it in the “ON” position on the third cycle
Check the Engine Light Blinks
- Count the flashes of the check engine light. The flashes will indicate a 2-digit error code (e.g., 2 flashes, a pause, and 3 flashes = Code 23)

Using a Diagnostic Tool (Optional):

For more detailed diagnostics, you can visit your local Polaris dealer or a well-equipped shop in your area. Or you could pick up a Dynojet Power Vision 3 ECU Tuner to read your own codes, monitor machine performance in real time, and more.

Locate the Diagnostic Port
The diagnostic port on General models is located under the hood near the firewall.
Connect a diagnostic tool
Use a diagnostic tool to retrieve, read, and reset Polaris General check engine codes

Common Polaris General Check Engine Light Codes

65590, 65591, 65592

If you get an error code like 65590, 65591, or 65592, you’re probably dealing with a clutch belt problem.

Most Polaris General check engine light codes are related to the drive belt and pop up after belt replacement. If you own any Polaris machine, this probably doesn’t surprise you.

These error codes tend to show up after belt replacements because the interior of the clutch is still dirty, or the belt wasn’t installed or broken in properly. This can lead to a misfire code due to belt slippage or damage. And, of course, these error codes aren’t generally included in your manual!

We’ve got you covered when it comes to installing and break in a drive belt properly. This guide will help you get your belt installed correctly the first time—and resolve your check engine light.

If you’re sure it’s not the belt, this code can also indicate an issue with spark plugs, the coil, plug wires, injectors, compression, timing, or a fuel issue causing a misfire.

520344

The 520344 error is generally related to the emissions system or O2 sensor. You can get an FMI (fault mode) of 15 or 17 with this error.

An FMI of 15 is often caused by a dirty air filter—a relatively simple fix.

An FMI of 17 is generally a result of a clogged fuel filter—another simple fix.

However, both FMIs can be caused by a bad oxygen/O2 sensor. And 15 can be an issue with the MAP sensors or caused by exhaust or intake leaks, which can be much harder to resolve.

FMI 17 can also indicate a bad fuel pump, which can cost you a pretty penny.

Cross your fingers and hope for a dirty filter if you see Polaris error code 520344!

3056 & 520209

Polaris General check engine code 3056 and 520209 are also fairly common. These errors generally indicate some problem with the O2 sensor as well.

The problem could lie with the sensor itself or bad wiring. The sensor may need cleaned, rewired, or replaced.

Other Codes

Your General can throw tons of other codes. Polaris shares just under one hundred SPNs, each with at least one FMI—and many have more.

We include a handy Polaris General diagnostic code table below to help you brainstorm solutions for the problem causing your check engine light.

Refer to your Polaris General service manual for a complete list of error codes and troubleshooting steps. If the issue persists, consult a Polaris dealer or technician for assistance.

Resetting Your Check Engine Light

1. Fix the Problem

Your number one choice should always be to fix the problem that’s throwing the code. Of course, that’s easier said than done.

But if you’re confident you’ve fixed the problem that was causing the light to come on in the first place, it may be time to try something else.

2. Ride Your Machine

If your General’s check engine light doesn’t reset, it doesn’t necessarily mean you did something wrong. Your UTV might just need some time to sort itself out.

The length of time required to reset your light depends on the diagnostic code you get, and it’s hard to tell which ones will take longer.

With some codes, the check engine light will reset after 4000 engine revolutions (assuming the issue is fixed). Others will take much longer and require many key-on and off cycles.

And there are some that won’t reset with this method at all and require specialized tools.

3. Use a Tool

If your General’s check engine light doesn’t reset on its own, you can try using specialized tools.

There are a number of tuners and other scan tools that can manually reset your check engine light.

If you don’t have one, don’t want to get one, or it doesn’t work for you, you may have a code that can only be reset using Polaris’ proprietary “Polaris Digital Wrench Software.” Your local Polaris dealer should have access to this software and be able to reset your light in this case.

If you’ve tried everything else and can’t get your check engine light to go away, you’ll have to take it to a dealer.

4. Disconnect the Battery (Last Resort!)

If you’re at your wits’ end, and you have to get that check engine light off RIGHT NOW, there’s one more thing you can try.

Before we tell you what to do, we’ll tell you why we consider it a last resort. This process resets your ECU, but it can inadvertently reset parts of your ECU’s memory, which can lead to more issues. Some are easy to resolve, but others might require you to replace your ECU if it’s permanently damaged.

In theory, this is a risky method. In practice, it seems to work out.

To reset the ECU, you have to disconnect the battery completely. Then touch your General’s wire harness terminals together. This will drain the capacitors and anything else in your ECU that holds a charge and is a guaranteed method of resetting your Polaris General’s check engine light.

Just remember—if you didn’t fix the problem, your check engine light is going to come back on eventually.

Say Goodbye to Your Check Engine Light

With your check engine light resolved, you can ride with confidence knowing your machine is ready for the ride ahead. And when your buddy’s check engine light turns on, you can save the day.

Because the most common causes of check engine codes are caused by belt issues, make sure to upgrade your drive belts, and say goodbye to your Polaris General check engine light.
