There’s nothing that kills a trail ride faster than your machine suddenly losing power. You press the throttle, but it just sputters and crawls. The check engine light glares at you from the dash, mocking your plans for the day.
If you’re seeing the dreaded 0 65613 2 polaris code, you’ve come to the right place. This error code can seem cryptic, but don’t let it intimidate you. We’re here to translate that technical jargon into plain English and give you a clear, actionable plan to get your Polaris running at full power again.
In this complete guide, we’ll break down exactly what causes this fault, the tools you’ll need to diagnose it, a step-by-step process to pinpoint the issue, and how to fix it right. Let’s get your rig out of limp mode and back on the trail where it belongs.
What Exactly is the 0 65613 2 Polaris Code? Decoding the Dash
When your Polaris throws a code, it’s not just a random string of numbers. It’s a specific message from your machine’s brain—the Engine Control Unit (ECU)—telling you what’s wrong. Let’s break this one down piece by piece.
Breaking Down the Numbers: SPN 65613
The first part, 65613, is the Suspect Parameter Number (SPN). Think of this as the “what.” It points directly to a specific component or system that’s having a problem.
In this case, SPN 65613 identifies the Accelerator Pedal Position (APP) Sensor 2. Your modern Polaris uses a “throttle-by-wire” system, meaning there’s no physical cable connecting your gas pedal to the engine’s throttle body. Instead, sensors on the pedal measure how far you’re pressing it and send that electronic signal to the ECU.
Understanding the Fault: FMI 2
The second part, 2, is the Failure Mode Identifier (FMI). This is the “why.” It tells you the type of fault the ECU has detected.
FMI 2 means “Data Erratic, Intermittent, or Incorrect.” This tells us the ECU is receiving a signal from APP Sensor 2 that it doesn’t trust. The signal might be jumpy, out of the expected voltage range, or—most critically—it doesn’t match the signal from APP Sensor 1. This disagreement between the two sensors is a major red flag for the ECU.
The Culprit: Your Accelerator Pedal Position (APP) Sensor
Putting it all together, the 0 65613 2 polaris code means the ECU has detected an erratic or incorrect signal from the second sensor in your accelerator pedal assembly. For safety, your Polaris has two of these sensors working in parallel. If they don’t agree on how far the pedal is pressed, the ECU can’t be sure what you’re asking the engine to do.
To protect you and the machine, it triggers a failsafe known as limp mode, drastically reducing engine power until the problem is resolved.
Symptoms and Common Problems with 0 65613 2 Polaris Code
While the check engine light is the most obvious sign, this code brings a few other frustrating symptoms along for the ride. Recognizing them can help confirm your diagnosis.
- Limp Mode: This is the big one. Your machine will have severely limited power and won’t accelerate properly. It feels sluggish and unresponsive, often capping the RPMs at a low level.
- Erratic Throttle Response: Before going into full limp mode, you might notice the engine surging or hesitating when you apply the throttle.
- Flashing Check Engine Light (CEL): The code will be accompanied by a solid or flashing CEL on your instrument cluster.
- No Throttle Response at All: In some cases, the machine might start but have zero response from the gas pedal.
The most common problems causing this code aren’t always a failed sensor. Before you order a new pedal assembly, consider these potential culprits:
- Corroded or Dirty Connector: Water, mud, and dust are the enemies of electrical connections. A bit of corrosion on the connector pins is a very common cause.
- Damaged Wiring: A wire could be pinched, chafed, or broken somewhere between the pedal and the ECU. This is especially common on machines that see heavy off-road use.
- Water Intrusion: A high-pressure wash aimed directly at the pedal assembly or its connector can force water inside, leading to short circuits.
- A Failed APP Sensor: Of course, the sensor itself can fail internally over time. This is often the last thing to check after ruling out the simpler issues.
Essential Tools and Safety Precautions
You don’t need a full professional shop to tackle this job. With a few basic tools, you can perform a thorough diagnosis right in your own garage. This is a great 0 65613 2 polaris code guide for the DIYer.
Your Diagnostic Toolkit:
- Digital Multimeter: This is non-negotiable. You’ll need it to test for voltage and continuity. A basic one from any auto parts store will do the job.
- Basic Socket and Wrench Set: To remove any panels or components needed to access the pedal assembly.
- Torx Bits/Drivers: Polaris loves using Torx fasteners, so make sure you have a set handy.
- Electrical Contact Cleaner: A spray can of this is perfect for cleaning dirty connectors without leaving a residue.
- Dielectric Grease: Essential for protecting electrical connections from moisture and corrosion after you’re done.
Safety First, Always
Before you start wrenching, always put safety first. It’s one of the most important 0 65613 2 polaris code best practices.
Disconnect the negative terminal of your battery to prevent any accidental short circuits. Work in a well-lit and well-ventilated area. If you’re not comfortable with electrical diagnostics, there is no shame in calling a qualified technician.
How to 0 65613 2 Polaris Code: A Step-by-Step Diagnostic Guide
Alright, let’s get our hands dirty. Follow these steps methodically. Do not skip straight to buying parts—nine times out of ten, the issue is simpler than you think.
Step 1: The Visual Inspection (The Easiest Check)
Start with your eyes. Follow the wiring harness from the accelerator pedal assembly as far as you can. Look for any obvious signs of damage.
Are there any wires that look stretched, pinched by a zip tie, or rubbed raw against the frame? Is the plastic conduit cracked or broken? Sometimes the fix is as simple as repairing a single damaged wire.
Step 2: Check and Clean the Connector
This is the most common point of failure. Locate the electrical connector for the accelerator pedal. Carefully disconnect it. You might need a small flathead screwdriver to gently release the locking tab.
Look inside both ends of the connector. Do you see any green or white crusty corrosion? Is there any dirt, mud, or moisture inside? Even if it looks clean, spray both the male and female ends generously with electrical contact cleaner. Let it air dry completely for a few minutes.
Before you reconnect it, apply a small dab of dielectric grease to the inside of the connector. This will help seal it from future moisture. Reconnect it firmly until you hear it click. Clear the code if you can, and see if the problem returns.
Step 3: Testing the Wiring and Sensor with a Multimeter
If cleaning didn’t work, it’s time to break out the multimeter. This is where you confirm if the sensor is bad or if you have a wiring issue. The exact wire colors can vary by model, so having a service manual is a huge help here.
- Check for Reference Voltage: With the key on (engine off), you need to verify the ECU is sending power to the sensor. You’ll typically find a 5-volt reference wire and a ground wire. Test for 5 volts between these two pins on the harness side of the connector. If you don’t have 5 volts, your problem is in the wiring leading to the ECU, not the pedal itself.
- Test the Signal Wires: If you have good power and ground, you’ll now test the two signal wires. With the harness connected and using fine probes to back-probe the connector, set your multimeter to DC volts.
- Perform a “Sweep Test”: With the key on, slowly and steadily press the gas pedal from zero to full throttle. Watch the voltage on your multimeter. You should see a smooth, linear increase in voltage on both signal wires. One might go from ~0.5V to ~4.5V, while the other might have a different range. The key is that the voltage change is smooth. Any sudden jumps, drops, or dead spots indicate a faulty sensor inside the pedal assembly.
If the sweep test fails, you can be confident that the pedal assembly needs to be replaced.
Fixing the Problem: Repair and Replacement Best Practices
Once you’ve confirmed the pedal assembly is the source of your common problems with 0 65613 2 polaris code, it’s time for the fix. A proper repair is a sustainable repair—one that lasts.
When to Replace the Pedal Assembly
The accelerator pedal position sensors are integrated into the pedal assembly itself. They are not typically sold as separate, serviceable parts. If your multimeter test showed a faulty sensor, you will need to replace the entire pedal assembly.
Sourcing the Right Part
You have two main options: OEM (Original Equipment Manufacturer) from a Polaris dealer or an aftermarket part. While aftermarket parts can be cheaper, electronic components like throttle sensors are critical for safety and performance. We at FatBoysOffroad strongly recommend using a high-quality OEM part to ensure perfect compatibility and reliability.
The Replacement Process
Replacing the pedal is usually straightforward. It’s typically held in place by two or three bolts. Simply unbolt the old assembly, disconnect the electrical connector, and install the new one in its place. Torque the bolts to the manufacturer’s specification.
After installing the new part, reconnect the battery, turn the key on, and slowly press the pedal to the floor and release it 2-3 times. This helps the ECU learn the new sensor’s range. Then, start the engine and verify the check engine light is off and throttle response is back to normal.
Frequently Asked Questions About the 0 65613 2 Polaris Code
Can I still ride my Polaris with this code?
It is strongly discouraged. While limp mode allows you to slowly get back to the truck or camp, continuing to ride with an erratic throttle signal is unsafe. The machine’s behavior can be unpredictable, and you should diagnose and repair the issue as soon as possible.
Will just clearing the code fix the problem?
No. Clearing the code will only make the light go away temporarily. The ECU continuously monitors the sensors, and as soon as it detects the same erratic data from the APP sensor, the 0 65613 2 polaris code will return, and you’ll be right back in limp mode.
How much does it cost to fix a 0 65613 2 code?
The cost can vary widely. If the issue is simply a dirty connector, the fix might only cost you a can of contact cleaner. If you need to replace the entire accelerator pedal assembly, the part itself can cost anywhere from $100 to $300 or more, depending on your Polaris model.
Is the accelerator pedal sensor (APP) the same as the throttle position sensor (TPS)?
No, they perform similar functions but are in different locations. The APP sensor is on your gas pedal assembly and reads your foot’s input. The Throttle Position Sensor (TPS) is located on the engine’s throttle body and confirms the physical position of the throttle plate. Both are critical parts of the throttle-by-wire system.
Tackling an electrical code like the 0 65613 2 polaris code can feel daunting, but it’s entirely manageable with the right approach. By following a logical diagnostic process—inspecting, cleaning, and testing—you can save yourself a costly trip to the dealer and gain valuable experience working on your own machine.
Remember to work safely, be patient, and trust your diagnostic steps. Now you have the knowledge and the confidence to solve this problem and many others. Get those tools out, get that rig fixed, and we’ll see you back on the trails!
