I Have a 2000 civic and I just changed the cat converter, now the CEL is on and giving me a code 67. Can someone please tell me what this code is? I resest my ECU once already, and it went away for like a dat then came back on.

 

Did you read the first thread on here, probably not, cause if you did then you would have read the rules also

 

you sure its 67 adn not 65 ? check the ecu code thread up there

 

--67 Catalyst System Efficiency: System below threshold, bad catalytic converter aka da CAT
3 seconds of searching got me this. First and last time.

 

Yea I read the first thread, but there is no code 67 in the list.
