2005 Scion xB 4 cyl Front Wheel Drive Automatic 304k miles

I just had the cat converter replaced at a dealership due to cat code coming up. Tech cleared all codes and indicators on dash went out. 20 min later dash indicators came back on. I took it back to dealer...after second diag check came up with bad O2 sensors. will bad O2s cause new converter to go bad?
