Re: P0440
440 code covers a lot of things.
You will need a scanner to get the other evap codes to help narrow it down.
Like small leak or large leak or what solenoid or sensor is not working.
First thing to check for is gas tank holding vacuum.
Check your vacuum and vent lines from engine back to fuel tank.
The get the good engine capable codes and post back code. no
