Let’s get you back in control and back to riding.
Why You Can’t Ignore That Blinking Check Engine Light
It’s tempting to just keep riding and hope the light goes away on its own. Sometimes it might, but ignoring it is a gamble you don’t want to take. That little light is the front line of your Ranger’s Engine Control Unit (ECU), the onboard computer that monitors dozens of sensors.
Understanding the benefits of 2013 polaris ranger 800 check engine codes is about proactive maintenance. The code points you directly to the system that’s having a problem—be it fuel, air, spark, or an electrical gremlin.
Letting a small sensor issue go unresolved can lead to bigger, more expensive problems. A faulty temperature sensor, for example, could cause the engine to run too rich, fouling spark plugs and potentially damaging the catalytic converter over time. Addressing the code early saves you money, prevents a breakdown, and keeps your machine running at peak performance.
How to Retrieve Your 2013 Polaris Ranger 800 Check Engine Codes (No Scanner Needed!)
One of the best things about these machines is that Polaris built in a simple diagnostic mode. You don’t need a fancy OBD-II scanner like you would for your truck. This is a crucial part of our how to 2013 polaris ranger 800 check engine codes guide, and it only takes a minute.
Step-by-Step Code Retrieval Guide
Your Ranger’s instrument cluster is the key. Follow these simple steps to make it talk to you.
Sit in the driver’s seat. Make sure the vehicle is in Park and the key is in the OFF position.
Press and hold the Mode/Override button. This button is usually located on or near your instrument cluster.
Turn the key to the ON position. While still holding the Mode button, turn the key one click to ON. Do not start the engine.
Wait for the diagnostic mode. Continue holding the Mode button. The gauge will cycle through its self-test, and then the main display area will show “WAIT” or cycle through some numbers. Release the button once the check engine icon starts flashing or the code sequence begins.
Read the codes. The screen will now display a sequence of numbers. It will show a main fault code (like 51), followed by a sub-code or Failure Mode Indicator (FMI) number (like 3). It will cycle through any stored codes. Write them all down!
Turn the key OFF. Once you’ve recorded all the codes, simply turn the key off to exit the diagnostic mode.
Understanding the Display
The codes are typically displayed in a two-part format: the SPN (Suspect Parameter Number) and the FMI (Failure Mode Indicator). For example, you might see “520207” and then “4”. This means SPN 520207 (related to the injector) and FMI 4 (Voltage Below Normal).
Don’t worry about memorizing these just yet. The important part is writing down the numbers you see. We’ll decode the most common ones next.
Decoding the Most Common 2013 Polaris Ranger 800 Check Engine Codes
Now that you have your codes, it’s time to play detective. This section will serve as your field reference for the common problems with 2013 polaris ranger 800 check engine codes. We’ve broken them down into common categories.
Fuel & Air System Codes
These codes relate to how your engine is breathing and getting its fuel. They are among the most frequent culprits.
Code 22 – Throttle Position Sensor (TPS): This sensor tells the ECU how far you’re pressing the gas pedal. A fault here can cause poor throttle response, stalling, or erratic idle. Often, the wires get stressed or damaged. Check the wiring harness near the throttle body for any breaks or corrosion.
Code 41 – Intake Air Temperature Sensor: This tells the ECU the temperature of the air entering the engine. A bad reading can cause the engine to run too rich or too lean. Check the sensor’s connection—it’s usually located on the airbox or intake boot.
Codes 51 & 52 – Fuel Injector Circuit: These codes point to a problem with Injector 1 (front cylinder) or Injector 2 (rear cylinder). The issue could be the injector itself, but more often it’s a wiring problem. Check the plug on the injector for a solid connection and look for any chafed wires.
Electrical & Sensor Codes
Your Ranger’s electrical system is its nervous system. A single bad connection can cause a world of headaches.
Code 26 & 27 – Vehicle Speed Sensor (VSS): If your speedometer is acting up or your all-wheel drive isn’t engaging properly, this is a likely cause. The VSS is often located on the transmission. Check for a clean, tight connection or physical damage to the sensor or its wires.
Codes 10, 11, 12 – System Voltage Issues: These codes indicate the ECU is seeing voltage that is too high, too low, or out of range. The first thing to check is your battery terminals. Make sure they are clean and tight. Then, check your voltage regulator/rectifier (often found near the radiator) and its connections.
Engine Condition & Misfire Codes
These codes can sometimes point to more serious internal issues, but always start with the simple checks first.
Code 61 – Engine Misfire Detected: This is a general code indicating one of the cylinders isn’t firing correctly. Don’t panic! The most common causes are simple: a fouled spark plug, a bad plug wire, or a weak ignition coil. Start by inspecting and replacing the spark plugs if they look worn.
Code 110 – Engine Coolant Temperature (ECT) Sensor: This is a critical sensor. A fault can cause hard starting when cold or overheating issues. It’s located on the engine head. Check the wiring first, as the connector can get brittle from heat.
Your Essential Toolkit for Diagnosing Check Engine Codes
You don’t need a full professional shop, but having a few key tools makes troubleshooting much easier. This is part of our 2013 polaris ranger 800 check engine codes care guide to being self-sufficient.
Digital Multimeter: This is your number one diagnostic tool. It allows you to check voltage, continuity, and resistance to test sensors and wiring.
Basic Socket & Wrench Set: For removing and tightening battery terminals, sensors, and covers.
Dielectric Grease: An absolute must-have. Use a small dab in every electrical connector you check to prevent corrosion and ensure a good connection.
Contact Cleaner: Perfect for cleaning dirty electrical plugs and sensor connections.
Service Manual: While our guide is great, having the specific service manual for your Ranger is the ultimate resource for wiring diagrams and sensor specifications.
Best Practices for Troubleshooting and Repair
Following a logical process will save you time, money, and frustration. Here are some 2013 polaris ranger 800 check engine codes best practices we swear by at FatBoysOffroad.
Start with the Simple Stuff First
Before you start ordering expensive parts, always check the basics. Is the battery fully charged and are the terminals clean? Are all the fuses in the fuse box okay? Did a branch snag a wire and pull it loose? You’d be amazed how many issues are solved by simply re-seating a connector with some dielectric grease.
The Importance of a Clean Machine
Mud and water are the enemies of electrical systems. After a muddy ride, take the time to gently wash your Ranger. Pay special attention to cleaning around the engine and wiring harnesses. This not only makes it easier to spot problems but also prevents dirt from working its way into connections.
When to Clear the Code (And How)
After you’ve fixed what you believe is the problem, you’ll want to clear the codes. On most 2013 Rangers, the codes will clear themselves after a few successful run cycles where the ECU no longer detects the fault. You can also disconnect the battery for about 15-20 minutes to reset the ECU, but be aware this may clear other settings.
Knowing When to Call a Pro
There’s no shame in calling for backup. If you’ve gone through the basic checks, tested the wiring, and are still stumped, or if the code points to a serious internal engine issue, it might be time to take it to a trusted mechanic. Being a smart DIYer also means knowing your limits.
Sustainable and Eco-Friendly Repair Tips
Being an off-roader means respecting the trails and the environment. Incorporating sustainable 2013 polaris ranger 800 check engine codes practices into your repairs is easy and responsible.
When you fix a problem causing a rich fuel condition (like a bad O2 or temp sensor), you’re not just fixing your rig—you’re reducing emissions and improving fuel economy. This is an eco-friendly 2013 polaris ranger 800 check engine codes benefit.
Furthermore, always dispose of old parts and fluids properly. Used coolant, batteries, and old electronic sensors should be taken to a proper recycling or hazardous waste facility, not thrown in the trash. This small step helps keep our riding areas clean for generations to come.
Frequently Asked Questions About 2013 Polaris Ranger 800 Check Engine Codes
Can I still ride my Ranger with the check engine light on?
It depends. If the light is steady and the machine seems to be running normally, you can likely limp it back to the truck or camp cautiously. If the light is flashing or the engine is running very poorly, shutting it down is the safest bet to prevent major damage.
Will disconnecting the battery clear the check engine codes?
Yes, disconnecting the negative battery terminal for about 15-20 minutes will typically reset the ECU and clear any stored fault codes. However, if the underlying problem hasn’t been fixed, the code will come right back as soon as the ECU detects the fault again.
Why did my check engine light come on after washing my Ranger?
This is a very common issue! High-pressure water can force its way into electrical connectors that aren’t perfectly sealed. This moisture can short a connection, triggering a code. The best fix is to go through major connections (TPS, injectors, voltage regulator), unplug them, dry them out with compressed air if possible, and apply dielectric grease before re-connecting.
Does a check engine code always mean an expensive repair?
Absolutely not! In our experience, the majority of check engine codes on these machines are caused by simple, inexpensive issues: a loose or corroded wire, a bad connection, or a relatively cheap sensor. The key is to diagnose properly instead of just throwing parts at it.
That check engine light doesn’t have to be a mystery. By learning how to pull and understand your 2013 polaris ranger 800 check engine codes, you’re taking a huge step toward being a more capable and confident owner. You’ll save money, avoid being stranded, and gain a deeper understanding of the machine you love.
