I have a problem with my car that I have never heard of anyone having with their car before and I am a mechanic. As I drive to work from my girlfriends house, when I get to a specific location the check engine light comes on. It has done it at that location every time the last 5 times I have come through there. It is a 2001 Toyota Avalon and the code it throws is P0440 which is "Evaporative Emission Control System Malfunction". It did it again on my to work this morning. Any other mechanics on here have any idea what it could be?
