TPS Fail

[Freeride1]

Just wanted to let you know what a TPS failure looks like. I started with a high idle coming out of a warm garage thursday night. Next morning it was fine. Saturday I had no reverse but it idled normal. Made it 5 miles and it started to cut out when I stopped then it stalled. It would stay running if I kept the Trottle Safety Switch engaged. It would start if I pulled it then grabbed the flipper to keep it runing but not until it fired initially. I tried unplugging the TSS under the hood (yellow 2 wire plug) and it was perfect for 10 minutes then when back to being screwey. Eventually I lost all sprak and had to re plug the TSS then unplug and re plug the TPS whech made it run lik it did with the stalling at idle.

My sled is a 2012 Pro RMK. I hear of another 2012 Pro doing the same thing and a 2011 that might have done the same all this weekend around me.

The TPS Polaris has used in the IQ and Pro seem to fall out of whack. There is a sticky thread in the Polaris section that shows you how to make a tool to calibrate it.

We had similar symptoms....high idle and no reverse and it was the ground to the bumper....cleaned it up and tightened and it went away.
Also make sure you don't have too much throttle cable slack activating the safety switch.??

I had the same issue, apparently water got in and corroded the connector pins. New one installed last week, hopefully it works now. Havent had a single ride yet this season without tps issues

The problem is moisture in the connector to the TPS, clean it up and use the contact grease

My connector was thoroughly greased with dielectric grease that I use on all my salt water WaveBlasters. The bumper was clean and tight since I had just put a new one on that week.

Did it start right after you replaced the bumper? That's exactly when it started on ours...when the bumper was replaced. If so, might scuff up the bumper and the mating surfaces for the ground. Fixed it on this one.
