Wierd 5v source wire problem on ecm harness isx15 cummins

So got the new exhaust pressure sensor and it got rid of all the codes. Crazy how that shorting out can affect all the sensors on the string including changing the voltage! Now I know next time something happens like that. Appreciate all the feed back and help. To diagnose with the cummins quickserve and insite requires a subscription to do that right? I see some have gone the Chinese route.

Fyi. In future if you want to load test a wire use a battery and an old style halogen head lamp. Also, if you look they all share the same 5v supply. So 1 bad sendor drags down all the rest, thus the multiple codes. Next time look into the the code with the most counts logged. Or if you have insite available monitor those sendors with same 5v supply. Sorry i was late to the game, i do not get on here but 1time every couple weeks. Keep ing it simple helps and dont overthink it
