Insite says turbo spinning when truck isn't running

[tree98]

2019 X15 performance 565 h.p. factory stock 75,000mi. I'm getting charge flow and turbo speed codes and insite shows the turbo spinning even when the truck isn't running. I pulled the speed sensor out, no change, unplugged it, no change. Tried a new one, no change. Re flashed ecm, no change. At this point I'm thinking it's gotta be the harness from the speed sensor to the ecm or the ecm itself right?
