Well my check engine light came on again today when i was driving home from school. so i check it out and it was cel 67 which was cat converter, does that mean i have to replace the cat?? My car runs fine everything seems to be working

 

i did a little searching and found some info, but some people were saying that i have to replace the second O2 sensor and the cat, but others say just the Cat, which on is correct??? and Also i hear that all HX models are still warranty by honda as long as it emission related, is that true??

 

Replace both of them and don't worry about it.
