P051D Catch can install
After installing UPR dual valve catch can i got a check engine Light Code P051D Crankcase pressure sensor circuit high. Ive checked immediate wiring nothing looks damaged. Has anyone experienced this?

I did a little research when I was thinking about getting a catch can for my truck. Pressure buildup over time was one of the problems that some people reported. I'm a little surprised that you'd see it immediately. Do you have it set up correctly? Are you flowing against a check valve? I'd troubleshoot air flow through the system to make sure there isn't a blockage.
Yah I had everything hooked up proper hoses facing right direction and all that. I removed the catch can and went back to stock. Code is still present even after clearing. I pulled the pcv valve it seems to be functioning correctly. Only thing I can figure is maybe the sensor failed do to debris or oil getting in there when I had it apart. Going to replace sensor and see if that does it. Thats all i can think of
