Purchased a 2020 RZR Pro for 25k from Neilsen Enterprises in Lake Villa on May 5, 2020. Almost right out of the gate I started receiving DO NOT DRIVE notices for recalls on dangerous items like no x stitching in the 6 point harness and exploding primary clutches. The dealer had my machine for nearly 6 weeks while fixing these items and so Polaris did extend everyones warranties for 6 months due to these issues. We then went through winter here in the upper MW and began planning a trip down to Brimstone, TN. Last week we went there and rented a VRBO then had an awesome day of riding. The second day my check engine light came on with only 485 miles on the machine. Read the diagnostic code and it indicated a failed wideband O2 Sensor destroying our trip as I could no longer drive my 25K vehicle for fear of going into limp mode at the bottom of a canyon etc. This is not only dangerous could could potentially be life threatening. When I got back from our destroyed vacation as no one had the part we needed I inspected the O2 sensor and it was basically finger tightened the crush washer on it is not even crushed you can see the middle of the ring. I called to dealers and both had the same reply that I would need to take it up with Polaris myself as a customer issue as their experience with Polaris 100% denial of every non-warranty claim every time even in a case like this where I was only 5 days out of warranty. Polaris when called responded of course with you have to take this to the dealer and they then have to submit a claim creating a circular nightmare and additional charges for me due to their absolute negligence. Steer clear of this company if that is the best they can do to resolve such a dangerous and irresponsible attitude towards their customers who pay out large sums of money for their product.

You need a better winch.Eeeek! That's a bold statement! I will say this, there may be nothing there that is life threatening in your rig, but I would disagree with there not being anything remotely challenging in a stock Pro XP. I have gone there the last two years for a week each time, and can tell you this for certain, in a machine with stock tires and suspension, there are definitely some challenging trails. And truthfully, there is one I can think of that in a stock machine is life threatening. I wanna say it was 79 maybe? The problem isn't the hill, it's the ruts. If you don't have the ground clearance of a rig like yours, you're in trouble.
Last year, I was out on the section that is removed from the main property, had to take road to get there. I wish I could remember the trail number off the top of my head but I think it was trail 24. Anyway, it was a blue trail that ended up being so washed out towards the top that we came around a turn and the trail was rutted into a V shape on the left side so deep that the top of the ground was above the roof of my machine. I made it up, babying the throttle doing a one wheel wheelie the whole way, just bobbing the front end. It was definitely puckering.

87Y is the life threatening one, not 79. 23 is the washed out one, not 24.

Been up 87Y many times in many different rigs from 800s to present. It's actually fairly easy. One of my favorite trails at Brimstone. The only trail at Brimstone that is life threatening is 75Y. You need to be have crazy to even attempt it so I don't count it in the list of trails normal people do at Brimstone LOL. However I recognize the difficulty level for trails is dependent on experience and the machine

I hate 75y with a passion, but yet always find myself on it when we go to brimstone. It’s the last 30’ that SUCKS. Other than that it’s a great trail lol

Ahh crap. You're right, it is 75Y, I was hasty and didn't look close enough on the map, I looked up a video to confirm. 87Y was actually pretty sweet, we went up it last October. I am not really good at remembering trail names, more of a guy that has to see the terrain to know where I am at.Been up 87Y many times in many different rigs from 800s to present.

Ya, I have a good winch, but have never used it on this machine other than to pull other people out.

The Pro XP units all have wideband O2 sensors. Evap units from the XP Turbo line also have them, and I think the 21 and up XP Turbo line have them as well.

Wow thanks for the replies like a few of you should check yourselves yeah its frustrating when you finally get out somewhere good for the first time and this happens. Nice that you pile on thanks to the few that actually respond like human beings not with tales of what you can do. Actually replaced the sensor and still getting the light so if anyone has some idea of what might cause that outside of the actual sensor please comment, Thank you

You will find you'll get much better responses if you drop the attitude. If you have replaced the O2 sensor and the problem still persist you probably have a wiring issue. Check the connector to make sure the contacts are clean and making a good connection. Check the wiring harness to make sure there are no broken or frayed wires.

FWIW my buddy and I were out in the desert a month ago breaking in his new machine. It tripped an O2 sensor code as well that would not reset. After riding for the rest of the day (limp mode but still had some fun in the sand) he set an appointment w/ his dealer. They replaced the O2 right off the bat and when that didn't fix it they actually began to check things out (classic shotgun method, I've worked in automotive repair for 20 years and I've been guilty just like the rest) and what they found w/ a smoke test of the intake tract was a loose intake hose. That's where I'd start, find a way or someone to smoke test the intake system for a boost/vacuum leak and also check the blow off valve (bov) and see if it is prematurely letting off pressure. These can all lead to skewed a/f ratios and set an O2 sensor fault. Good luck, once you get it sorted out I'm pretty sure you'll be back in happy camper land and enjoying your new machine like you hoped to

Thanks for the good info I am going to have to head down that road as replacement and inspection of the wiring harness front to back I can find nothing. Something has to be causing it started looking for a wet plug somewhere to as we hit some puddles hard too out in TN you know the ones that don't look very deep by the power lines and such. Thanks I will post if I get it resolved
I am having the same code, I have ~2100 miles on my machine. At first when the light came on, it would come on while accelerating and then turn off when letting off the gas. But then it came on and stayed on for a while, so I check my voltage while riding (in limp mode) and I noticed my voltage was down at 11.2 volts. I was running all my accessories (2 air compressors, stereo, light bar, whips, etc) and riding pretty hard. When I turn everything off the voltage works its way back up to 13.5 volts and the code will clear itself while riding a bit. The last time the light came on it wouldn't turn off until I stopped the rig and let it idle for 60 seconds or so with all accessories off, then rode back to camp pretty hard without it coming on again. I am thinking the low voltage is affecting the reading of my O2 sensor and causing the code, thoughts?

Yeah I also got a weak battery with mine when purchased even though I use a battery minder it would drain like there was vampire voltage draw. Ended up buying 2 and replacing the new one and added second battery kit. Bought a wideband sensor from aftermarket assasins and also replaced the crap intake tube that tends to suck shut when you get on the turbo. Like was mentioned above a couple times after doing these installs took it out for a 30 minute ride and light disappeared and (fingers crossed) has not returned. RPM makes a silicone big fatty tube and if you have the cash get a silicone J tube and charge tube while you are at it.
It sounds like you answered your own question.
The feedback provided to the ecm is voltage. There is a range of expected voltage. If you are only feeding the circuit with 11 volts, that would definitely skew the voltage sent to the ecm.
Sounds like you are due for a second battery and an isolator.

Cheapest wideband sensor is the one from Aftermarket Assasins around 125 dollars

What "bolt-on" alternator would that be? Only ones I know of are ZRP & UTV INC, both $2k+
Larue $1275
