Catalytic converter warning indicator. More likely oxygen sensor circuit issue.

It may be due to the oxygen sensor like I previously mentioned.

i'm having the same issue with a JDM 1993 Accord SiR, and it's not throwing a code just the cat warning light

i've replaced the O2 sensor and checked i've got continuity from the harness plug to pinouts A11 O2 sensor (usually A6 on OBD1, but A11 for the Accord) and D14 O2 sensor

anybody know what pinouts i need to check for the other 2 wires, or any other things i can check?

any help very much appreciated

Chris
