How to Fix A Polaris Ranger Speedometer That Will Not Work/Jumps Erratically Code 84

[@michael.clingingsmith_3517]

I'm getting the 0 84 2 code on my 2012 Ranger 800 xp. I can be stopped in neutral, increase the RPMs and I can hear a low noise coming from under the bed behind me, that's when the check engine light comes on & it throws the code. I'm not having Spedo issues, do you know what that noise can be? It's hard for me to pin point the low noise over the high RPMs of the engine.

I’m not sure. Wish I could help but hard to say without seeing it in person
