What you might want to try first is have the codes cleared which most auto parts stores offer this for nothing (unless you have a programmer then you can do it yourself). Pour in some fuel injector cleaner into your gas, put a new air filter on. And when you fill up your gas tank, crank the cap several times when you put it back on.
See if the codes come back on after that.

This indicates that a part of the EVAP control system is no longer functioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses.

A code P0440 could mean one or more of the following has happened:
· The gas cap is not installed or working properly
· The purge solenoid has failed
· The canister is plugged and not working properly
With a P0440 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:

• Remove and reinstall the gas cap, clear the code, and drive for a day and see if the codes come back.
• Inspect the EVAP system for cuts/holes in tubes/hoses
• Inspect for damaged or disconnected hoses around the Evap purge solenoid
• Check and/or replace the sensor
• Check and/or replace the purge valve
• Have a professional use a smoke machine to detect leaks

Verifie si le bouchon du réservoir d'essence est bien en place, c'est la plus grande cause de ce code...

Check your gas cap, if it is not screwed on tight it can **** air in and give you that error code but i believe it is P0440 as emissionwiz states....
