Ok everyone I went to Autozone today because my SES light has been on for a year. Just been to damn lazy to go earlier. But anyways, I did the search for these codes that I got and couldn't find them in the ECU Fault thread. The codes were P0420 which they told me meant "Catalyst efficiency below threshold (bank 1), and the second was P1447 which was Electric SYS Closure valve flow fault. What I'm trying to see is if any of you guys have got either of these codes. If you have what exactly am I looking at as far as maintainance and what it cost to get fixed. Or if possible can I fix these things with basic tools. Any help would be good.

Thanks.

 

Bump. Anyone??
