Catalytic converter issue

[isanchezgdl]

Hello everyone, I have a question, if the catalytic converter overheats and for this a fissure appears in the shield or in the pipe a litle before or after the cat body, is possible this may cause the error codes for OS2 sensors after and before the cat?, I have the OS2 error of bank 1, sensor 1 and 2 but the cat have a hole in the shield or pipe (right now are working on repair this), is possible get this fail codes because the problem in the cat?
Thanks a lot

Yes, the loss of back pressure could result in a code being thrown by the O2 sensors.
