i got to take my first ride on my ace today, mostly woods behind my house. about a hour into the ride the check engine lite came on, i shut it off and got my manual out, but when i went to check the code it was gone. when you shut the engine off you loose the code, i didnt know that. it come on again latter and i got the code. the manual says there will be three numbers, one in place of the gear selector, one in place of the clock, and one in place of the odometer. so the code i got was 0,2,84. i went to check the book for the code and i caint find it in there. so the ? is does anyone know what that code means.

I did a Google search on Polaris diag codes, but the lists I came up with do not go as low as 0 or 2, nor as high as 84.
I'll try and get my hands on an ACE service manual.

Did you look on pg 45 of your user's manual?
Those numbers don't seem to match up either, but maybe this will help you re-evaluate how you are reading the code.
Or it may be that the service manual has a different, more complete set of codes and your is not in the basic one in the user manual.
Anyway, I'd be talking to the dealer straight away about a trouble code.

I purchased my Ace on Friday, and within the first mile the check engine light came on for about 2 seconds and then went off, it did that twice on the first ride. On Saturday I went for a 20 mile ride and it came on again for a couple seconds halfway during the ride. I have rode 3 miles since Saturday without any check engine lights. It was always in low range at idle or very low rpm's when the light came on. I have checked the battery connection and all fluid levels, everything seems in order, it runs fine, it did not store any codes that i could retrieve, my dealer is over three hours away, so i am just going to ride and see what happens for now.

well i took it in to the dealer today and they ended up installing a new speed sensor for either a ranger 900 or a razor 900, caint remember witch one he said, think it was the ranger.
there had been a recall on them and it was the same part number as mine. he said it also came with some kind of a spacer that they also installed. i`m just going to have to wait and
see if my light comes back on. there not even sure if it`s going to work. it took over a year to find a fix, and recall the ranger. he said the ace is so new he didn`t even have service
info on it yet. now that`s a little strange.

My check engine light went out before I got it loaded on the trailer.Dealership told me to bring it in anyway so they could check it.It was the speed sensor.They told me to drive it awhile and if it comes back on they will order a sensor and replace it.Thanks billbo for posting it helped to have an idea of what it was.

Today as i moved the Ace from the garage to the wash area the check engine light came on and did not go off, this time i could retrieve a code. 0 84 2 Does anyone know what this is? or where i can see a list of codes? It is not in the owners manual. If it is the speed sensor, what does the speed sensor on the Ace do? My 13 Silverado had one, It would cut off at 95 mph, I could not have that, had a custom tune done, now it does not cut off!

I did some research over on the Rzr forum. It seems that on a Rzr 900 that code means: Speed sensor: Data erratic or intermittent (or missing) and to look on the right hand side of the transmission just to the rear of the shifter linkage and check for damage or loose connection. I do not know how that compares to the Ace, but it is a starting place to check.

I found this in the Polaris ATV forums, from a fellow in NY with a 2011 X2 Sportsman 550 w EPS:

"Mine does this from time to time, it has to do with the vehicle speed sensor being a bit to sensitive. This almost always happens when shifting from reverse to forward ot vice versa/ When you shift gears, the shift fork in the transmission engages a gear, the gears may "jump" as they mesh together. The teeth on the gear that the speed sensor reads off of sees 2 gear teeth go by really quickly and the ECM interprets this as high vehicle speed and the CEL comes on.

There are a few threads on this, there is no real fix for it. Mine has done it 7 or 8 times in 1600 miles. I spoke to my dealer about it and he didn't have much to say other than to replace the vehicle speed sensor. A new sensor made no difference in mine. It doesn't happen often enough for me to worry about it, so I just ride it lol. The code always goes inactive and CEL always goes off on the next shift."


And this in the PRC Ranger Club Forum from a fellow with a 2014 900XP LE White Lightning Ranger :


  • Took the Ranger to the dealer about the code. When hooked up to their machine they saw the saved code but couldn't do anything about it. Ranger was running perfect. They pulled the sensor and checked it another way and nothing. Last time I rode the code came up and I let the dealer know and document it but was told if its running fine don't bother bringing it in! This is just an fyi post!






Sounds like we have a few Polaris owners experiencing this problem across different models, and are having the sensors replaced. But do we know that it is the cure, or is it what the dealers are doing in hopes that will fix it. Sometimes manufacturers leave the dealers hanging until they determine what is actually happening. It's always possible a certain component was made and didn't quite meet the standards required.

I applaud Polaris dealers for doing all they can, taking care of their customers, and diligently working to find the fix, sometimes without direction from the manufacturer. All warranty work does not pay off! Manufacturers don't always pay their warranty claims, especially if you have the same issue more than one time. And sometimes it costs more to file the claim than it does to just fix the customer's problem and eat the cost of fixing it.

Here's an example of a manufacturer hiding an issue, and making their customers pay to fix their problem unless they are the "squeaky wheel"!

My boss had an engine failure in his top of the line '07 GMC Yukon Denali @ 67,000 miles. We found a "dealer only" (not public knowledge) tech bulletin that stated that if trouble codes were these certain numbers, the engine ran rough and had a miss, then after removing the valve cover, you should find one or more valve springs laying loose on the head. If so, replace the engine!!! This was the GM Vortec 6200 engine. He had to press the regional GM service manager to get any help with the cost, as it was a private bulletin. Apparently, they had some valves that were not properly heat treated, and they could break and fail at any time. GM was apparently hoping that the majority of them would get out of the GM warranty period, and then they could redact the bulletin and charge customers for their own defective parts problem. The valves may have been sourced from China, or who knows where. Things can happen anywhere, but to try to cover it up or hide it, not recall the problem, that's the bad thing for the general public.

If the codes come back in the machines with the new sensors installed, I would be inclined to lean towards the explanation about the false speed being picked up in the computer from the gearing "jumping" and throwing the code. Polaris may be trying to replicate the error which throws the code with equipment connected to determine the actual malfunction. I am just glad that at least the code clears out and the vehicle goes back to operating properly until it gets thrown again. That's different than what is in our autos and trucks. That code stays in the computer until a scan tool clears it out...and the vehicle may or may not run properly. I would hate to pay a tow bill or push a dead ATV out of the woods!

We'll see what transpires.

I like the way you think!...I purchased the 4 year warranty on mine, usually right before the warranty runs out Iam ready for the new and improved model anyway.
