I have a continuing problem with my 2014 sportsman 570. I keep getting the 520194 7 error code especially after the machine has warmed up. I have adjusted the throttle cable and get a positive change in voltage with the safety sensor.
I checked the TPS sensor and getting 0.46v at idle position as recommended. The throttle never actually sticks but it throws the code and then the engine goes into limp mode until it cools off. Really becoming a problem and I don't want to just start replacing expensive sensors without some knowledge as to what is really wrong.
Any help would be great.

I have a 2014 570 doing the exact same thing as well. I have checked everything I can think of. Seems to only do it when it’s good and warmed up after riding awhile. I’ve checked all the wiring, checked adjustment on the TPS, adjusted throttle cable every which direction, on and on. Did you ever figure out what was causing it?
