That car has a total of four converters under it. Two are parts of the exhaust manifolds, the third is attached under the engine while the fourth is back under the car under the passenger side. They are items 3, 5, 12, 13 in the second image. Both of the front converter units have O2 sensors in them (9 and 10), the downstream sensors are 7 and 8.
The two downstream units do not have O2 sensors in them (3 and 5) so if you have a code it likely isn't either of those. However they can get plugged.
Hope that answers the question, if you have more questions about them just ask.
