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.
