02 sensor location

I've got a '90 B190 with the 460 engine - does anyone know if there is more than one o2 sensor?!?
I replaced one that is just before the catalytic converter. I've seen references online to one or two more, but can't find anything.

The one you found should have been between where the left and right bank come together just before the cat. On a 90 that's all there is.
