My car failed NJ State Inspection for Codes P0440 and P0443. What are these codes for. My service engine light is on--It has been on for the past couple of months. Any help is appreciated. They will not pass for inspection unless this is fixed.

Is this something that I can fix myself--Could it be the gas cap.

your gas cap being not tight enough could definately be your problem(s)..... check this link... http://www.ene.gov.on.ca/cons/3733.pdf

buy a new gas cap, then have your light reset. Hopefully it doeant come back on. If it does its not something you can do on your own. Evap system is a apin to work with at times.

Doesn't Nj inspection suck I fail People all day long for just having the check engine light on . but as far as you go make sure if you do the work yourself that the book they gave you is filled out corectly and you have all your part receipts. and if your don't wanna fix it yourself chose a guy from the book. Oh and once the light gets reset. drive around for about 500 -1000 miles mixed city and highway. and don't wait longer then 45 days once you do it's full inspection all over agian. Does sound like a gas cap not being tight enough.
