Error code P1202 P1200

I got an error code P1202 today, then I got it back to shore, checked it again and code was P1200. What do I need to replace?

I simply had a loose connection to my blow by valve on the TOPS (top of the oil separator). Unplugged and replugged it a few times, wrapped it with some tape (to keep it from wiggling), good to go!

I ended up dumping quite a bit of oil when that valve didn't open (not sure from where). But fixing the connection eliminated the P1200 error, and no more oil in the hull. Whew!

Do you know, if I replace front and back sensors, will oil come out? I'm thinking it might on the back one.
Thanks
