Fuses to O2 sensors?

Are there fuses related to the O2 sensors?

Still dealing with a CEL after Bank 2 S1 sensor was replaced, twice now.

Getting a constant 16538 code of no activity in B2 S1 O2 sensor.

Thanks.

Wiring from ECU to O2 sensor more likely, though there is a fuse for the HEATING side I believe.

I think he'd get a different code for a heater issue.
