What Is Polaris Code 520 344?
The Polaris code 520 344 is a problem that may occur when riding an ATV. This code indicates that the fuel pump is not operating correctly, which can lead to several issues with the vehicle.
Usually, the system is in diagnostic mode when this code appears. The possible reason for going into diagnostic mode is if there is a problem with the engine or some other critical component of the ATV.
Another possibility is that the electrical system is at fault, such as a short circuit happening due to wires getting damaged. In this case, the diagnostic mode would help to identify and fix the issue.
What Is 520 344 17 Polaris Code?
The Polaris code 520 344 17 is a specific error code that can be generated on an ATV rider. This code may indicate a problem with the internal electric configurations and the fuel system.
Again, if this code is generated, it is recommended that you take your ATV to a repair shop to have it inspected and repaired.
4 Reasons Behind The Polaris Code 520 344
The fuel pump of the ATV may not work for several reasons inside the system, and the pump itself may not be at fault.
Let us look at 4 real reasons and how to solve the issues.
Reason 1: Engine Management Failure
The most common causes of engine management failures on ATVs are lack of oil, dirty or plugged air filters, bad spark plugs, and a low or dead battery.
To solve an engine management failure on an ATV, you’ll need to identify the correct problem.
Solution: Replace The Battery And Spark Plugs
The first step is to check the oil level and add oil if necessary. Then, inspect the air filter and do some cleaning. Or replace it depending on what serves the needs.
Next, look at the spark plugs and replace them if they default. The way to know is by removing the spark plugs from the engine and inserting it into a spark plug tester. If there is no spark when you turn on the tester, then the spark plug needs to be replaced.
Finally, charge the battery if they are going too low. And so, you will be seeing the engine delivering better performance.
Reason 2: Problem In The Ignition System
Several problems can occur in an ATV’s ignition system, but some of the most common problems are broken connectors and faulty ignition coils. If you experience any problems with your ignition system, you should first check the wiring and connectors for damage or corrosion.
Solution: Replace The Faulty Parts
Damaged wirings can be replaced, as mentioned before. You should also check the ignition coils for damage or defects and replace them alongside the connectors.
To do the process, remove the vehicle’s old wires, ignition coils, and connectors. Be sure to label each wire or connector as you remove it so that you can easily put them back in the correct place later.
The code will not appear again as the inner components are new and fresh to provide ultimate performance.
Reason 3: Issues With The Fuel System
Fuel system issues on an ATV can be caused by various problems, such as a clogged fuel filter, water in the fuel, or a bad fuel pump.
If you are having trouble starting your ATV or it is not running properly, you should troubleshoot the fuel system to determine the cause of the problem. It can be done by checking the fuel level in the tank; if it is low, then you can add more fuel.
Look at how the solution works-
Solution: Clean Or Replace The Fuel Filter
First of all, check the fuel filter; if it is clogged, you can easily clean it. If there is water in the fuel, you can drain it by removing the petcock and draining the tank.
To clean a fuel filter, you will need to do the following:
- Locate the fuel filter; it will be found in the engine compartment near the firewall.
- Disconnect the fuel line from the fuel filter and place a container under the line to catch any spilled fuel.
- Using petroleum jelly, coat the entire outside of the fuel filter. Any contamination of dirt and debris can be taken out with this approach.
- Suck out as much of the dirty fuel as possible using the turkey baster or siphon hose. Discard any fuel that has been sucked out.
- Soak a rag in diesel fuel and use it to clean off any remaining petroleum jelly from the filter housing. Wipe until all traces are gone.
- Reattach the fuel line to the fuel filter and close your vehicle’s hood.
You can also add a fuel stabilizer to the fuel tank to keep the fuel from going bad. Again, if the problem doesn’t solve, you will need to replace the fuel filter completely.
Reason 4: Faulty Powertrain
A few things can go wrong with an ATV’s powertrain, but the most common is a failure in the ignition system. As the ignition system is not working, the powertrain won’t work either in terms of delivering power to run the engine.
The powertrain transmission system can be fixed by following a few simple steps.
Solution: Fixing The Powertrain Transmission System
The first step is to ensure the engine is turned off and the key is out of the ignition.
Then, find the hood release lever located at the vehicle’s front. After locating the lever, pull it towards you and lift it on the hood.
The cover from the engine needs to be removed. This can be done by loosening and removing the screws that anchored the engine in place. Then, gently lift up the cover and pull it away from the engine.
You can see the transmission system after removing the cover. The first step in fixing the transmission is checking all fluid levels. The fluid levels should be checked using a dipstick near or near the transmission.
If fluid levels are low, add more until they reach their correct levels.
After checking and correcting all the fluid levels, you can begin repairing any damaged parts on the transmission system. There are many different types of transmissions, so it is essential to know what kind of transmission your vehicle has before attempting any repairs.
Important Note: Certified mechanics must do all the repair and replacement work at the repair shop, do not try to do this yourself to be safe and sound.
How To Prevent the 520 344 Error Code
A few things can be done regarding regular maintenance to prevent the 520 344 Error Code from appearing on an ATV rider.
You should be regularly checking the fluid levels in the ATV. If the levels are too low, this can cause the code to appear. It is also essential to clean the ATV’s interior and exterior more often.
Other than that, do drive carefully and avoid doing anything that could cause damage to the ATV.
These tips should help prevent the 520 344 Error Code from appearing on an ATV rider.
How Do I Reset The Polaris Error Code?
If you are experiencing an error code on your Polaris ATV, reset it by turning off the machine and unplugging it from the power source. Remove the key from the ignition, wait for the power source to reconnect, and plug in the key.
What Does Code 520344 Mean On A Polaris Rzr?
The code 520344 is a diagnostic code associated with the Polaris RZR. It indicates a fuel system problem, which should be addressed as soon as possible.
Does Disconnecting Battery Reset Codes?
There is no clear consensus on whether or not disconnecting the battery on an ATV will reset the codes. If you are having trouble with the codes on your ATV, it may be worth disconnecting the battery to see if that clears them up.
At the end of the day, flashing Polaris code 520 344 means you need to upgrade the vehicle’s internal system. We have told you what you need to do depending on the situation.
Hopefully, things will work out fine.
