Has anyone seen this code on a 2018 Mountain Cat? (P1755. Engine RPM sensor circuit malfunction) This morning my sled was starting to burp and fart on the trail, especially when i hit some bumps, i assumed it was the throttle safety switch. It was happening off and on through the day but after we stopped at the cabin and the sled cooled off it got really bad, any throttle it was stuttering and burping but wide open seemed to wake up.

Any ideas?

OK well thanks for all your help everyone! :face-icon-small-con


Turns out inside the velcro loom strapped to the frame, the connector for the engine rpm sensor wasn't completely clicked together and was losing contact on bumps throwing the code and making the sled run like crap.

The end.
