How many service resets are there for this model car? I bought it used and eventually found out the upstream oxygen sensor needed to be replaced, which is now replaced and isn't reading with the ecu. I tried the manual ECU reset, but couldn't get it to work. Then I found out scan tools have resets that tell the ECU to relearn which is what I'm trying to find out now. I'm asking how many resets there are for my car since I've replaced so many parts including the fuel pump. The scan tool companies can't seem to tell me.
