code 41, O2 sensor fixed, then code 67 ???
Primary heated O2 sensor heater circuit fault ( sensor 1 ) was replaced, code 41 vanished and followed by code 67, Catalyst system efficiency below threshold.
Honda Dealer would replace a cat for $1,200 plus labor, shop supplies, etc and taxes.
High flow cat or a resonator does not come with O2 sensor fittings.
Has anyone installed a test pipe on OBD-II CIvics without hooking up sencondary O2 sensor?
