Cam Phase Sensor!!

I’ve got a 2011 rzr 4 that i bought used, and the bike is throwing the cam phase code, but the only problem, is that there is no cam phase sensor on the engine. I know its supposed to be right above the oil filter.. The plug from the harness is just sitting there but there is no where for the sensor to go. The bike starts and runs and everything, just has a sputtering issue at around 3,000 rpm on take off. Any help is appreciated.
