All codes related to rear o2s. That includes heater codes. All cat codes. Not just p0420 and p0430. All evap codes.
Personally i would put p06DE to "no mil", you want the code there for diagnostic but you have less of a chance getting forced into limp mode when it fails.

The list of codes is very long.
