I have an 06 Accord that needs a CA smog test done. The battery was removed, causing all sensors to reset and, for the life of me, I can’t get the catalytic converter sensor to ready. I’ve run through the steps to reset it in the manual and driven for 2k miles now, but still no luck. Short of “drive it more,” is there anything else that could cause this to stay incomplete?

    If the O2 sensors are old and lazy or the cat is marginal you might have a pending P0420 cat efficiency code.

    I would look at o2 sensor voltages and waveforms to see if one or both sensors are not up to spec.
