O2 Sensors Location

Hi guys i have been reading that there are 3 sensors. I am aware of the front 2 sensors. Is it possible that I only have 2 sensors?

The 3rd one is behind the cat and is a sub-sensor.

My 1GS is a California car so I would not be surprised if the Federal cars do not have the sub-sensor. It only monitors a/f anyways as opposed to the main sensors that the ecu relies on.

Edit: Confirmed on alldata that the Federal models only came with 2 oxygen sensors.
