I recently had a cel pop up with a P0440. I purchased a brand new gas cap considering it was cheapest and easiest to do and didn’t fix it. Next I’m going to replace the eve app control valve. Where is this located I cannot find anything on the Internet. Is it in engine bay? Or under car in rear? Thank you….John

Engine bay, driver side mounted to the fuse box behind batt

Do you ever smell raw gasoline? A code p0440 indicates a small leak anywhere past the charcoal canister. This could be a leak in the gas tank itself (fuel pump o ring, evap hose ring, or vacuum lines, filler neck etc.) Less commonly, the vacuum lines in the engine bay or a cracked charcoal canister. You can test the evap purge valve manually using a scantool, before running out and wasting money on a replacement.

Ok thank you. I will check everything over good tomorrow. Hopefully I can figure it out. It runs fine no issues. Just hate seeing the cel on. I don’t ever smell raw gas either.

So I just seen both hoses popped off of it probably when I was working on it the other day in that area. I hooked them back up. Cel still on but I guess it might take a little bit to go away. If I try to clear it with my code scanner, it won’t erase.
