HELP with a Code Pull! "P0455"

[AmBo]

I went to autozone to have my Service Engine Soon Light code pulled. The guy pulled the code "P0455" and said it read something about an EVAC leak large? Something like that? What could this possibly mean?!

BTW the code means: "P0455 Leak or Blockage Detected in Evaporative Emission Control System."

Is this severe and fixable by myself?

Check the gas cap to make sure it's on tight. If it's not that let me know and I'll post a crapload of other things to check.

Ok rock on. So just take it off and put it back on? Stupid gas men! We don't pump our own gas in Jersey

First try turning it like you're tightening it and make sure it's on all the way. If it is, unscrew it and make sure it's not damaged or cross-threaded, then screw it back on, and go back to autozone and have them delete the code for you.

well the guy at autozone said all he could do was pull teh code, not delete it. is there a reason for this?

You can also just disconnect your battery, then leave a door open for a few minutes, to discharge whatever power is left in the capacitors. That will delete the code as well. If you get a MIL again after you fixed the gas cap, let us know.

the story i heard for auto zone not clearing codes was because they got sued (?) because someone brought there car in and they cleared the code and the idiot pulled out in front of somebody and they blamed it on auto zone. i used to work there part time and thats what my boss told me, hed let them erase the code but he wouldnt

Wow...what a dumb story. I still think it's cool though that they pull the code for you for free.

I'm going to be using my friends scanner to reset the code Tues. Hopefully it won't pop again...
