1991 240sx: Crankcase Position sensor code

[vancouverbc]

When I first retrieved the codes, I got Injector leak but when I cleared the codes and tried again I got the code for crankcase position sensor. When I did the mode 2 drive test , I was reading rich in idle and above 2000 rpm. The other day I fail emissions with high hydrocarbons and carbon monoxide. My oil level is high. Any thoughts?

Is the crankcase position sensor an integral part of the distributor? I dont see it sold separatedly so I assume so.

When mine went bad I had to buy the distributor so I also think it's integral.
