i have a code 440 and yes i have changed the gas cap

it has an evap leak. i was not thinking about the gas cap.
you need a scan tool, smoke machine and a voltmeter to find the issue. evap problems are one of the toughest to track done. a shop can do this to diag the issue and give you a bid.

valve is located under intake manifold cover, front, behind throttle body on top of intake manifold. easy replacement for around $40.
