2012 sportsman 850 eps Everything issues

Hey everyone,

This is my first time posting mostly just enjoy the threads and good place to pick up technical data but I am stumped this time. I have a 2012 sportsman 850 EPS with 1300km on it (for the American friends 809 miles). I purchased it second hand last summer with 600km (372 miles). So the issues I am having first was 3234767 Asm., Switch Shaft decided to grenade locking me in lo range. took apart replaced added new fluids put everything back together perfect ran great. Next came the all so famous TPS code 520194 – 7 dealer inspected replaced the TPS sensor and set it. Start quad up now throwing code 51-3 TPS voltage to high as well as 102 – 2 Manifold Absolute Pressure Sensor and now throwing 520194-7 again. All sensors were replaced the first go around and to top it all off shifting became increasingly harder and now it is stuck once again in high range now. To note the belt was recently replaced and the old one had normal wear on it and clutches were checked for proper shimming etc. So if anyone has any thoughts on this it would be greatly appreciated as I do love my 850 but if this keeps up there will be a outlander 1000 with my name on it.
