E70 P0363 Fuel Censor Circuit Code Post repair

[Mrchin]

Hi,
We had an AC issue. Hot air. Had a mechanics replace the AC Compressor. Replaced ok and working but now we got it back and it’s throwing the P code for the Furl sensors on both banks A,B

Wife also jus t filled up $85 and show low fuel all in the same day.

Unless it’s a coincidental same time bad sensor. What could be the cause? PCM flashed badly or wired during install?

Thanks
Martin
