That is correct, you have an oxygen sensor before the Catalytic but you also have an oxygen sensor on the exhaust manifold as shown on the picture. The way to get to it is to first secure the vehicle on jack stands, put a jack under the engine with a 4x2 piece of wood. Loosen up the center engine mount, drop the engine slowly, then under the car you can reach the oxygen sensor. It is extremely tight but doable.
