Says Catalyst System Low Efficiency (Bank 1)

I can't find the thread where someone else was talking about this.
Is it just one oxygen sensor or several which throw this code?

Seems like someone may have referenced it in this thread:

Welp...
They reset the engine code after changing the oil and it has not come back after driving 200 miles.
no idea of the cause.

Would be nice if it was just a one time fluke. Thanks for the update and keep us posted.
