I was getting repeated P0420 codes, I asked the dealer to confirm the diagnosis, dealer told me I needed the front CAT. Having no income right now, I got a reman from smithcat.com and put it in, reset the codes, ran the "idle learn" procedure. The P0420 came back after about 30 miles. Just to be sure I reset it again and the code didn't come right back (yet, but it's only been ~20 miles since) but in the meantime by scantool/ODBWiz tells me that "Heated Catalyst", "Evap System", and "AC Refrigerant" signals are not "Available". Does that info tell me anything?
The sensors came out easily and looked good visually so I re-used them.
I did get the ECU reflashed once before when I brought the car in for routine service. I'm guessing that was a one-time upgrade, yes?
'02 manual.
TIA
