Default Catalyst not being read at DEQ

I recently went to DEQ. I got a "not ready" on the catalyst. They told me their computer was not reading my Cat. I recently disconnected the battery because my CEL was on. I did the turn the key on and off trick and got 2 codes, P0440 and P0441. When I disconnected my battery my CEL went off. I drove around both city and highway for about 50 mile total before going to DEQ. Any thoughts??
