RE: check engine light/code P0455
Thank you for your reply. Sorry I didn't reply sooner, My truck had to be put on hold. Anyways, we had the cap checked and they said it was fine. I bought it 3 years ago. If I rule out the cap, any idea what else it may be? Someone told my husband to check some canister in the back. I'm not sure what it's called. Do you know anything about that? Recently I was driving with the window down and the fumes coming from my truck were real bad. The fumes have a strong fuel smell. My husband is pretty good with cars but is totally stumped with this one. We want to avoid taking it to the shop if possible, so any other info you can provide would be great! Thank you!
