Hello, I was recently in an accident deemed not my fault, my 250 was in perfect condition otherwise. After the accident when I recieved my car from the shop, they gave it back to me with the check engine light on and told me it was my O2 sensors. I ran a scan on them and the Bank 1 has low voltage, Bank 2 has high. What could be a cause of both of them to have voltage problems? The mechanics refused to believe the accident had anything to do with it, which is complete BS. I got hit on my passenger side, 11K in damage. Any advice would be phenomenal.

Did you already sign over the check to them? I would stop payment and call the insurance company to let them know. It definitely sounds like it's related to the accident, but without wiring diagrams, it's hard to diagnose. Dual failures at the same time is very rare. There is most likely a common problem that triggered both errors. But without more diagnostics or diagrams, it would be a crap shoot.
If the sensors are the same part numbers, I would swap them and see if the low/high voltage follows. If they don't, then it's not bad sensors.
