Polaris Ranger 800 Fuel Injector Problems: [Causes & Fixes]

A wrecked fuel injector can affect the UTVs performance. And in the long run, the engine can face difficulties to start. That is why it’s better to solve the problems beforehand.

So, what are the Polaris ranger 800 fuel injector problems?

The problem codes you can get are 6515, 6513, 6525, 6523, 35983, 35984, and 52024113. This code can come if the fuel injector, connecting wire, or ECU is damaged. Changing or repairing the wires can solve the first 6 codes. And the last code needs fuel injector calibration to be programmed.

That was a quick look at the problems. But you do need the details to fix them. Let’s get into the details of how you can solve the problems. 

How to Check Problem Code on Polaris Ranger 800?

To see the problem code, you need to use the mode button on the speedo meter. Press on the button and scroll down to the check engine option. You will find it’s written, “NCK ENG.” When the screen shows that, press and holds the mode button for 3 seconds.

Then the screen will appear the problem codes.

What are the Polaris Ranger 800 Fuel Injector Problem Codes?

There can be a lot of different problems with the fuel injector. The check engine sign will light up if anything is wrong with the fuel injector. But how do you know the problem is with the fuel injector?

In the table below, I have given all the problem codes related to fuel injection. So, if this code appears, that means the problem is fuel injection. You can also get these codes if Polaris ranger injector is not firing. 

All of these codes are related to fuel injections. Now let’s see which codes mean what. And how you can solve them. 

How to Solve Fuel Injector Problem Codes?

There are a few problems that follow the same solutions. But some of the problems require specific solutions. That is why I have included all the solutions to this problem. So, let’s start

Code 6515

When you see code 6515 on the speedometer, that means the problem is on the MAG side. MAG side means, the driver-side fuel injection. You need to repair the fuel injector cable. So, what can be the reasons for this problem? 

Reasons

• Damaged wire
• Faulty fuel injector
• Faulty ECU
• Faulty Connection 

Solution

In order to solve this, follow the steps below. But before that let’s get the list of the tool you will require.

• Wrench
• Pick tool
• Flat head screwdriver
• Wire cutter wire stripper
• Wire crimper
• Soldering machine
• Wire tape

Now let’s move on to the steps.

• Remove the fuel injector cable from the engine. The cable will be under the back seat. Make sure to remove the driver-side cable. Detach the cable from the port and the harness.
• Discard the white tape from the cable. Afterward, detach the terminal from the connector. Use the picking tool to remove the connector. 
• Hold the connector and detach the crimp from the cable. Afterward, slide the water seal on top of the cable. Make sure not to damage the water seal, cause we need to use that again. 
• Break the metal crimp on by rocking it back and forth. Cut the damaged, exposed wire using the wire cutter. Afterward, use the wire stripper and expose the new wire. But make sure not to expose more wire than you need. 
• Bring the water seal down and attach the crimper using a wire crimper. Afterward, use the soldering machine to solder the exposed wires. 
• Attach the terminal back to the connector. Make sure to attach it the right way. Also, the polarity of the wire is right. Push the wire in the connector and pull it back to lock it in. 
• Use black tape to cover up any exposed wire. Afterward, take the blue silicon seal from the connector in the engine. Attach the seal on the cable connector and plug it into the port. 
• Attach the harness and use a zip tie to secure the harness. The zip tie will lock the cable to the harness. So, in the future, the cable will not damage.

This is how you can solve code 6515. After the steps, start the engine and check in the engine light is on or not. 

Code 6513

When you get code 6513 that means, there is a short voltage on the MAG side. The problem is similar to code 6515. That is why the solution to this problem is the same as well. You need to fix the damaged cable as we discussed on code 6515. 

Reasons

The reasons are the same as code 6515.

Solution

Follow the steps addressed in code 6515.

Code 6525

The code 6525 is similar to code 6515. The only difference is the problem is on the PTO side. The PTO side is the fuel injector cable on the passenger side. The problem is referred to as an open circuit on the fuel injector cable. 

Reasons

The reasons are similar to the causes of code 6515.

Solution

To fix this follow the steps mentioned in code 6515. 

Code 6523

This code is similar to code 6513. The only difference is this is on the PTO side. So, the solution to this problem is the same as code 6515. You have to fix the cable wiring on the fuel injector cable. 

Reasons

• Damaged wire
• Faulty fuel injector
• Faulty ECU
• Faulty Connection

Solution

Apply the measures discussed in code 6515. 

Code 35983 and 35984

When the output voltage on the injector is higher than the limit, you can see code 35983. And when the output voltage is lower than the limit, you’ll see code 35984. But, the reasons for this problem are similar to code 6515. So the solution to this problem is the same. 

Reasons

• Damaged wire
• Faulty Connection

Solution

Follow the solution for code 6515. If the check engine light is still on, you made it into replacing the connecting wires. 

Code 52024113

When the fuel injector calibration has not been programmed, you can see this code. Calibration makes sure the engine is getting the right amount of fuel. So, you get better fuel efficiency. Also, do not use the vehicle when you see this code.

Over time when you use your vehicle, the calibration can go off. That is why you need to calibrate again. But, why does this happen?

Reasons

• Rough and bumpy driving
• Calibration has not been programmed

Solution

You need to take the fuel injector to a mechanic to program the calibration. Calibration requires precision computing. And the system can be difficult to get in hands at home. That is why it’s better to be done by someone professional. 

FAQs

How to Remove Fuel Injector from Polaris Ranger 800?

To remove the fuel injectors, detach the fuel injector connections first. The connectors are located under the back seats of the UTV. After you remove the connectors, use a wrench to take the fuel injector line off. 

What are the Symptoms of a Bad Fuel Injector?

Engine misfire is the most common thing when you have a bad fuel injector. Also, idling will go rough with a defective fuel injector. You might see the speedometer needle dance as well. And sometimes, the UTV won’t even start. 

How to Replace Fuel Injector on Polaris Ranger 800?

To replace the fuel injectors, you need to remove them first. Before you start working, make sure the engine is not running and is cold. Remove the old fuel injectors under the back seats. Attach the new ones using a wrench with the fuel injector line. 

Verdict

So, that was everything you needed to know about Polaris ranger 800 fuel injector problems. A fuel injector is a really important part. And it’s never a good idea to use the UTV with a check engine light.

Always take protective measures when working under the hood. And take help from professionals if you’re not feeling confident.
