In this article, you’ll learn the common symptoms, the tools you’ll need, a simple recalibration procedure that often solves the problem, and how to troubleshoot deeper if the issue persists. Let’s get that RZR fixed and get you back on the dirt.

What Exactly Is the 0 656 13 Polaris RZR Code?

First things first, let’s translate this numeric code into plain English. The numbers you see aren’t random; they follow a specific diagnostic format known as SPN/FMI.

In this case, the 0 656 13 Polaris RZR code breaks down like this:

SPN 656: This points directly to the Power Steering Control Circuit.
FMI 13: This specifies the fault type, which is Out of Calibration.

So, when your RZR displays this code, it’s telling you: “The Electronic Power Steering (EPS) system’s position sensor is not properly calibrated.” The brain of your RZR doesn’t know which way the steering wheel is pointed, so it disables the power steering assist as a safety precaution.

Your RZR’s EPS isn’t just for comfort; it’s a critical performance and safety system. It makes maneuvering through tight, technical terrain possible and reduces driver fatigue. When it’s not calibrated, the system can’t provide the correct amount of steering assistance, leading to the problems we’ll cover next.

Common Symptoms and Problems with 0 656 13 Polaris RZR Code

When the EPS system is out of calibration, your RZR will give you some clear warning signs. Ignoring them isn’t an option, as unpredictable steering is a major safety hazard on the trail. This is one of the most important 0 656 13 polaris rzr code tips we can offer: pay attention to how your machine feels.

Here’s what you’ll likely experience:

Loss of Power Steering: This is the most obvious symptom. The steering will become extremely heavy and difficult to turn, reverting to full manual steering.
Intermittent Assist: The power steering might work for a moment and then cut out unexpectedly, especially during turns. This can be jarring and dangerous.
“PS” Warning on the Dash: Your instrument cluster will likely display a “PS” (Power Steering) or “EPS” warning light, along with the check engine light.
The Code Itself: The numeric code 656 13 will appear on your digital display, often cycling with other information.

The biggest problem is unpredictability. One moment you have easy steering, the next you’re fighting the wheel. This can make navigating obstacles like rocks, ruts, or tight corners incredibly difficult and unsafe.

Your Step-by-Step 0 656 13 Polaris RZR Code Guide: Tools and Diagnosis

Alright, let’s get our hands dirty. The good news is that this code can often be fixed with a simple procedure and some basic checks. This section is your complete 0 656 13 polaris rzr code guide for getting started.

Essential Tools and Prep Work

Before you start, gather a few basic tools. You don’t need a full professional shop, but having these on hand will make the job much smoother.

Basic Socket and Wrench Set: For checking battery terminals and other connections.
Digital Multimeter: Absolutely essential for checking battery voltage and wiring continuity.
Dielectric Grease: A must-have for protecting electrical connections from moisture and corrosion.
Your RZR’s Service Manual: This is your bible. Procedures can vary slightly by model and year, so always have the official manual for your machine.

Make sure your RZR is parked on a level surface with the wheels pointing straight ahead before you begin any diagnostic work.

How to 0 656 13 Polaris RZR Code: The Recalibration Procedure

Often, the sensor just needs to be “re-taught” its limits. This simple recalibration procedure resolves the code a surprising amount of the time. It costs nothing and only takes a minute.

Disclaimer: While this is a common procedure, always consult your specific model’s service manual to confirm the steps.

Park on Level Ground: Ensure the vehicle is on a flat surface and the front wheels are pointing straight.
Key On, Engine Off: Turn the ignition key to the “ON” position but do not start the engine. Let the dash cycle through its startup sequence.
Turn Full Lock Left: Slowly and deliberately turn the steering wheel all the way to the left until it stops. Hold it there for a second.
Turn Full Lock Right: Now, slowly turn the steering wheel all the way to the right until it stops. Hold it again.
Return to Center: Bring the steering wheel back to the center (straight-ahead) position.
Cycle the Key: Turn the ignition key “OFF,” wait for 10-15 seconds, and then turn it back “ON.”

For many riders, this simple sequence is all it takes. The EPS control module relearns the full range of motion of the steering rack, clears the 0 656 13 polaris rzr code, and restores power steering function. If the code is gone, start the engine and test the steering. If it’s back to normal, you’re good to go!

Beyond Calibration: Deeper Troubleshooting Tips

If the recalibration didn’t work, don’t panic. It just means we need to dig a little deeper. The most common culprit after a failed recalibration is an electrical issue. Low voltage or a poor connection can easily confuse sensitive electronics like the EPS module.

Step 1: Check Your Battery and Connections

A weak or dying battery is the root cause of countless electrical issues on modern UTVs. The EPS system draws a significant amount of power, and it’s very sensitive to voltage drops.

Check Battery Voltage: Use your multimeter to check the battery voltage with the key off. A healthy, fully charged battery should read between 12.6 and 12.8 volts. If it’s below 12.4V, charge it fully and have it load tested.
Inspect Terminals: Make sure the battery terminals are clean, tight, and free of corrosion. A loose or dirty connection can mimic a bad battery.
Check Grounds: Inspect the main ground wire from the battery to the chassis. Ensure it’s clean and securely fastened.

Step 2: Inspect the EPS Wiring Harness

The EPS unit is typically located under the dash or on the front firewall. Trace the wiring harness coming from it. You are looking for common problems that can trigger the code.

Look for Chafing: Check where the harness might rub against the frame, steering components, or other sharp edges. Vibration can wear through the insulation and cause a short.
Check Connectors: Unplug the main connector to the EPS unit. Look for any signs of corrosion (green or white powder), moisture, or bent/backed-out pins. Clean the contacts with an electrical contact cleaner and apply a small amount of dielectric grease before reconnecting.

Step 3: When to Call a Professional

If you’ve performed the recalibration, confirmed you have a strong battery, and thoroughly inspected the wiring with no luck, the problem may lie within the EPS unit itself. The torque sensor or the internal control module could have failed.

Testing these components requires specific procedures, pinout diagrams from the service manual, and a high degree of confidence with electrical diagnostics. At this point, replacing the entire EPS unit is often the only solution, which is a costly and involved job. This is where the benefits of 0 656 13 polaris rzr code knowledge come in—knowing your limit. If you’re not comfortable, it’s time to take it to a trusted mechanic or your local Polaris dealer.

0 656 13 Polaris RZR Code Best Practices and Prevention

An ounce of prevention is worth a pound of cure, especially with complex electronics. Following a good 0 656 13 polaris rzr code care guide can help you avoid seeing this code in the first place.

Proactive Electrical System Care

Your RZR’s electrical system lives a hard life—it’s subjected to water, mud, dust, and constant vibration. A little proactive care goes a long way.

Whenever you’re working on your machine, make it a habit to apply dielectric grease to any major electrical connectors you come across, including the one for the EPS. This simple step seals out moisture and prevents the corrosion that causes so many issues.

Also, invest in a quality battery tender. Keeping your battery optimally charged between rides extends its life and prevents the low-voltage faults that can trigger codes like this one.

Sustainable and Eco-Friendly RZR Maintenance

Thinking about a sustainable 0 656 13 polaris rzr code solution might seem odd, but it comes down to smart choices. When replacing parts, especially electronics, opt for high-quality OEM or reputable aftermarket components.

Cheaper, low-quality parts fail more often, leading to more waste in landfills. A quality EPS unit will last longer, perform better, and reduce the overall environmental footprint of your repairs. If you do replace a battery or an electronic module, be sure to follow eco-friendly 0 656 13 polaris rzr code practices by disposing of the old parts at a designated e-waste or recycling facility.

Frequently Asked Questions About the 0 656 13 Polaris RZR Code

Can I still ride my RZR with code 0 656 13 active?
