Polaris Misfire Code??? Explained here

[@kellydavis4954]

thanks for clearing that up ,never understood why some videos say the belt causes a misfire

[@Moose2888]

2018 ranger 1000xp. I get the misfire code at start up while engine is cold and machine not moving. If engine hot and I start it I don't get the code. After driving it couple minutes it clears code.

[@Hunterworks]

Can’t say but that’s not clutch.

[@ethanh9535]

What would cause my 2017 Polaris RZR 1000 S to backfire/like a popping noise when I start slowing down only. Any help would be appreciated. Thanks.

[@Hunterworks]

An exhaust leak can or if you have a tune on it and you are not letting off the gas pedal all the way

[@damourssteeven]

2023 9r 3miles in to the ride. Got a DET and flashing chek engine. Changed plugs nothing. Would like to know more on what is the general purpose of the DET system. 91oct pump gas

[@Hunterworks]

what is a 9R? Take it back to the dealer since so new, we have not dealt with the DET system on it

[@damourssteeven]

@@Hunterworks its the new polaris rmk 900r 2023.

[@Hunterworks]

@@damourssteeven not sure utv have it. The trick is finding out why it’s denominating. But I’d have it back at dealer. Ecu might have too much timing in it

[@damourssteeven]

@@Hunterworks i added octane booster in it and it is less intense i only get the DET code while going full throtle. im bringing it to the dealer tomorow asap

[@richardshafer8105]

I just dropped my Polaris ranger XP 1000 off to the dealer with a misfire code 1st thing he said the belt was hourglass due to belt slippage and I said I don’t think so I think it’s more than that it only has 2600 miles on the belt and they said nope it’s a belt issue and I said They need to checked for something else that is causing damage to the belt. Their reply is there tech has been doing this for 13 years and he knows what he’s doing.

[@Hunterworks]

What year ?

[@tomayers6289]

Id have to agree belt, we change belts alot more often then 2600 miles.

[@Hunterworks]

@@tomayers6289 you need to contact me.

[@Wearedoom]

@@tomayers6289 I've never had a belt last 500 miles lol I have learned a lot on these videos though and just recently put the HW belt on, so we'll see.

[@Wearedoom]

Kind of like brakes, 500 miles and they are done. Found a lot better luck with brass though.

[@badboyoak]

After I went to the duraclutch I have been chasing the misfire fault. So brand new clutch primary and secondary. It normally will clear After a bit. Also put new plugs in so any help would be appreciated.

[@Hunterworks]

They offer a free flash for that if it started within 100 miles of the install

[@davidpic-gu5tc]

after i went to the duraclutch, now i'am getting the misfire fault 65590. brand new clutch primary and secondary. It normally will clear After a bit.

[@Hunterworks]

No, they offer a free ecu flash for false misfires.

[@davidpic-gu5tc]

hi, how did i get the free eco flash, thanks david

[@davidpic-gu5tc]

HI, how do i get the free eco flash? thanks! david

no need to reply, i found the sheet with the information i need to send in the ecm.

Hello good evening. I have 2 2015 Rzr 1000 XP. 1 of the unit's is experiencing lots of misfires. I have replaced the fuel pump, spark plugs, belt, and I still keep getting a misfire. Would it be the clutch or would it need to have the ECU reflashed? The other unit is fine and doesn't experience these issues. Thanks for your time.

[@Hunterworks]

If the belt is slipping or if there is a clutch issue making rpm raise out of the expected range it can be the clutch

[@grantjohnson3110]

Any idea what could cause a intermittent code. I come on every time we ride but always clears itself pretty quick

[@Hunterworks]

Sometimes it is hard to find until it stays until cleared manually. I can only tell you what to look for in the clutch to see if that is it. if you hit a rev limiter when you floor it at any speed it is the clutch

[@seanheavner358]

How do you reset the codes on a 2012 rzr800s ​@@Hunterworks

[@Hunterworks]

@@seanheavner358 Sorry, I do not know, I would assume once you fix what is causing the code it goes away, heard undoing the battery for a few min too. Not really my area of expertise.

[@angelromero5249]

what can a 2017 rzr have when I'm accelerating and I let off the throttle it makes a weird noise and stops moving then it's hard to change between the different gears PRNLH

[@Hunterworks]

I would start with our how to troubleshoot a primary clutch video

[@IronHunteroutdoors]

What if you ranger is idling rough and when driving it it seems like it wants to back fire or stall out

[@Hunterworks]

Are you getting a code on the dash?

[@IronHunteroutdoors]

@@Hunterworks I just realized that you can check that so I will when I get home

[@dusting4188]

2013 ranger 800efi changed plugs and injectors/cables only running on one side pull the plug on driver side still runs but bad pull the passenger side it dies ? Any ideas ? Just changed oil air filter everything but the belt code 651 5 was on before

[@Hunterworks]

No such thing as a belt code, that comes up as a injector issue but since not clutch related I am not a huge help on this one

[@dusting4188]

@@Hunterworks thanks for replying !!!👍

[@ATV_HowTo]

Got the two misfire codes, belt was definitely worn. Clutches bad too. Replaced primary, secondary, and got new belt. Codes still present. Any ideas?

[@Hunterworks]

Not enough information email me [e-mail] tell me the vehicle what exact brand clutches what collect kids etc. and I can help

[@heiditye7566]

2019 Polaris rzr 1000 eps s4 code 65590 7. Any idea? Doesn’t seem to be giving us any issues but engine light is on with that code

[@Hunterworks]

Without looking that actual code up, no pretyy sure is a misfire code though, have you floored it and ran it to top speed yet?

[@anthony46021]

I installed dalton clutch kit on my 2015 xp4 1000 and set it up for my 32" tires. Ran 28" 9 paddles in the dunes and threw misfire codes and went into limp mode. Are the smaller tires my culprit?

[@Hunterworks]

potentially, put your 32 back on it and run it hard and see, you might have gotten you a new clutch issue you didn't know about

Hey I bought a 2021 Polaris rzr 1000 xp high lifter drove it one time it ran fine, 2nd drive I hit a hole and it went under and after getting it unstuck it’s throwing same codes here. I’ve replace spark plugs new belt. Afterwards I got to 65 miles an hour and then I turned around drove back and rpm hit 8k and then dropped to 7k back to 8k and then dropped again and code misfired. I had the gas pedal all the way down when this happen? Any ideas?

[@Hunterworks]

You need to get into the clutch and see what kind of damage you see of just full of mud and water

[@nautique_la2178]

So what’s the fix?

[@Hunterworks]

Depends, if the clutch is causing it you fix the clutch, if not clutch then good luck can be an array of things

[@joshrobins6577]

Great video, good information.

[@mickeysouth6580]

I have a code coming up 1 51 ,what is the meaning of this code

[@Hunterworks]

a google search says this "code 51 is a stuck open injector on cylinder number one. It runs poorly at lower speeds because it can not handle the excess fuel being dumped into the engine"

2023 RZR Pro XP only 4 miles on it yes 4. I just started the machine up and 2 misfire codes 65590 & 65592.

better take that one back to dealer, might be the bad clutching set up and wrong washer in primary but so new, I would take it back

@@Hunterworks oh yes, totally stock.. it’s at the dealer…this machine is an absolute Monster! No real need to modify it. Literally have to try Not to do wheelies. Come to find out, it’s just a faulty switch.
