Crankshaft position or phase?

I have a 2011 rzr 800s and it recently threw a code 636 with the small 2 under it. Now I feel like an idiot to ask this, but is a crankshaft position sensor and the crankshaft phase sensor the same thing? And is it the plug that’s right by the oil filter on the passenger side? I can’t find anything that looks like the position sensor when you google it, it looks like the phase sensor? Just a small black plug attached to the motor with a small bolt.
