Default CMP, EVAP, IMT, MAF, and IAT sensors wiring problem

So I have been trying to find the wiring problem that is causing my CMP intake, CMP exhaust, EVAP, MAF, IMT, and IAT sensors to all stop working. Someone found the diagram for me and it appears like all these sensors have a red/blu wire connecting them all to a loop. I'm guessing this is a ground wire and I could just reground each sensor using the red/blu wire. But I don't want to mess it up even more when I don't fully know what I'm doing. I can't really think of anything else that would cause all these sensors to fail at the same time. Also the only engine codes popping up are a low voltage signal for all the sensors. If anyone could shed some light on this for me I would appreciate it so much. Heres the diagram that was shared with me.
