Default O2 sensor question

Is there a relay or fuse for the O2 sensors?

It didn't take long to google it, but from the 5 seconds of research I just did on the subject there is a fuse, but I don't see a relay. That doesn't mean there isn't one, just means my research hasn't shown one yet.

I checked my owner's manual, didn't show one but that doesn't mean much. Trying to read the FSM, but not seeing much there either.

Appreciate it since you found what I couldn't if you'd share where it is please?

It should tell you which fuse is for the oxygen sensors inside the cover to the fuse box in the engine bay.
