Someone correct me if I'm wrong, as I may be off base here...
My understanding of the OBD-II diagnostics is that it reports
about the sensors in the system, whether they are working and
within range or not. What sensor is there that would finger
a catalytic converter as being bad? That is, what does the
OBD-II diagnostics test to determine the cat is bad.
