I have a 2003 Honda Civic HX. OBD code P1490 comes up when I access my PCM. I'm told that has to do with my catalytic converter however I have two on this car. Can I as a DIYer diagnose which cat is giving me problems or do I need to see a profesional? If I can diagnose this myself how do I do that?
have the same problem?
