Generally a higher milage vehicle possibly a bad oxygen sensor or catalytic converter. What year, how many miles?

I have access to the info, general manager of independant service facility.

SOrry to resurrect an old post, but could this have been caused by a bad tank of gas? I, too, have this error coming up on a scan tool, along with a P0051 "HO2S Bank 2 Sen 1 Heater Circuit Low" error. My wife filled up at an off brand, never before been used gas station and these errors came up 2 days later.

I just wrote them down and cleared them and will monitor them in the near future. Any thoughts?
