Well went to ride today and my reverse dont work, and having it pinned in deep snow it would kinda seem like it would skip half a beat. It was idling low so i turned it up. Maybe TPS out of wack?? Ideas?? thanks

TPS FIRST
TPS TPS TPS.
Thanks!
I had the same thing as glassman but dealer ended up replacing my tps under warranty.
Replace tps. I had the same issue and after making adjustments and riding again it came back. Dealer should warranty it.
I'll give them a call after school and see what they have to say. Normally really good to me and treat me right.

I have had this issue on and off for the last month also. It is definitely getting frustrating. My sled won't idle right and the reverse won't work. I have had it in at the dealer 3 or 4 times. Every time my sled is dry in the morning it will work, but after riding for an hour or two it will start acting up. They just replaced the TPS and supposedly sealed up the connection, but when I went riding on Saturday, the reverse wasn't working again and the engine won't idle high enough to keep the screen on. Polaris either needs to buy a different kind of TPS system or completely re-route the harness and change connectors to eliminate this problem. I am seeing way too many people out there with this problem. I honestly do not know what to do next, anybody have any ideas?
I am not total convinced that it is just the TPS causing all these issues. The pins are actually quite large on the connector and they have alot of spacing between them. It could actually be caused by moisture in getting to the ECU or some other connection. They have micro pins and I think the moisture would be more of a factor. My advice is to pull the hood off and pull apart every connection, let it dry completely and di-electric all of the connections. If this doesnt cure it, then there is some other issue. The fact that the ECU connectors are on the side and the moisture could actually collect at the bottom of the connection and "arc" the two lower pins is quite likely.

Moisture in the TPS is causing common problems as described above. 3 out of the 3 PRO’s I ride with (including mine) have had a moisture issue causing the symptoms. Filling the connector with dielectric grease is the solution. A hot engine with snow spray on the engine creates a high moisture environment and these sensors are EXTREMELY sensitive to any resistance change within the connector. The grease is an insulator and fills the voids and keeps the moisture out. Simple solution.
There could be other problems resulting in similar symptoms, but I'm seeing a consistant pattern, with the TPS and moisture. In the cases I have observed, it's been after a heavy snow, where snow is coming up over the hood. The sled is shut off while warm, and the problem starts.

Took it in to dealer and TPS was all messed up. I guess on bright side reverse works and it idles and 2200 now ha. Only thing that sucks is that when you stop it stays lingering at 3500 forever.

Well, last night I went through most of my connections, the two worst ones with water were the lower ECM Connector and of course the TPS Connector. After drying out the ECM Connector, my sled still wouln't idle properly or go into reverse. I then dried out and used dielectric grease on the TPS Connector, and then my sled started running like a dream. I hope this is not something I have to do after every single ride.
