This has to be the third person i've heard on here with the same problem, same year.

I'm hoping they do a recall because i can't figure mine out either....

It's most likely NOT the sensor, most of the time its the wires and plug going to it. Check them for broken wires and wires pulled out of the plug. Polaris makes a plug rebuild kit for it. 9 times out of 10 thats the problem..
