Question about Cadillac Seville

Aftermarket converters can cause catalytic converter monitor issues, these are not O2 sensors, they are catalytic converter efficiency monitors, I know they look like a O2 sensor but they are very different in how they work, what are the codes you are getting.

The AF sensors are uupstream and the O2 down stream. The car' s computer tests them and it is saying your cats are bad. If you have a scan tool you could look at the data and see what the sensors are seeing. The Af sensors are the ones that control the fuel ratio in the car while the O2's just watch. AF's would be the one to change but there is no garuatee that the codes won't come back.
