  • '98 civic P0420 code and O2 sensor?

    Got a P0420 code come up on my '98 civic. I have been doing research and the voltage values on the 2 O2 sensor are very close. Does that mean that catalytic converter is no longer working? Should the value on sensor 2/post catalytic converter be significantly higher than sensor 1/pre-catalytic converter?

    I haven't had the power loss issue that others have talked about, still runs great!!

    I think that this means my converter went out?

    Thanks
Working...
