Lost several systems at once

[KJKWillys]

Hoping someone can help me before I have to take to the dealer. Wife started our 21 JLU last week and dash reads “fuel sensor unavailable”, “TPMS unavailable”, “service 4WD”, “start/stop unavailable”, and the “check engine”. Jeep starts and runs fine. Thinking it would have to be a module or bus for all these system to stop communicating at once. Anyone have any ideas???
Edit: was able to pull code P0463 with an obd2- Fuel Level Sensor “A” Circuit High.

Mice ?? I had a similar challenge with our Audi (different but many lights/systems) and it was mice chewing wiring.

I don’t think so…. Put it on the rack traced all the wiring from the back to the front. Beyond frustrating

Ok. I’m not sure how the wiring runs in our Jeeps. I had to remove some of the interior and center console to find it! What a PITA.
