I had my code for the cel read today and it said p0443 "evaporative emissions control system purge-control valve circuit malfunction." Where should I start on fixing this issue? All my truck info is to the left, and it now has 140 thousand miles. I've read it can be an evap cansister, or evap canister purge valve. I need to start with the most likely cause of the light (besides fuel cap not functioning. already tried that one lol). Any help appreciated!
