P2272 code, just the O2 sensor itself?

Pesky P2272 has popped up on my 2008. That refers to the downstream passenger side O2. Emissions O2, not the upstream ones used for AFR etc. Yes I could disable in the tune but I have factory cats, no point. The wiring looks ok, has anyone had experience with an O2 sensor just randomly going out?
