2007 Ford Explorer - Check Engine Light

[shanna.lundberg]

I have been having some problems with my 2007 Ford Explorer - Check Engine Light is on. I brought it to AutoZone and had them hook it up to the scanner. P0455 was the code, I proceeded to purchase a new gas cap from the dealer. Code was cleared and now 2 days later it is back on again. Can anyone help with what the problem is....

Check for a vacuum leak, possible cracked fuel filler neck or bad charcoal canister valve.
