Several months ago the CEL went on in my 1996 V6. Autozone pulled the codes which were P0133 (O2 sensor) and P0420 (catalytic converter efficiency low). The light went out by itself after 2-3 weeks. Two weeks ago it came back on. This time the only code was P0420. Should I infer from this that the converter is going and that somehow caused the O2 sensor code previously? Or could a failing O2 sensor cause the P0420 code? I certainly don't want to replace the converter if it ain't broke.
Are emission components covered by a longer warranty? I've read something about 8/80,000 miles on emission systems.
