Question Heater Core bypass

Hey,

I removed my heater core after it went out and am bypassing it using HELP! bypass caps. I'd rather just do a U-turn with a piece of hose but the inlet/outlet are different diameters. Anyone out there do something similar? What is the sensor that plugs into one of the metal coolant pipes that's connected to the uppoer intake manifold? Does it take incorrect measurements when bypass CAPS are used since flow is eliminated? Can those two pipes (all one piece) be removed and the hole in the manifold be plugged? Will it set off a check engine light or will something else get screwed up if that sensor is disconnected? Thanks.
