    Sure that is a 3.6? I don't see that engine 08.
    OR what is the code or reason you want LDP ..... will then be able to add picture.

    PS advise if this is Calif emissions.

    P0440 GENERAL EVAP SYSTEM FAILURE

    with no other codes -
    I would split possibilities - do you have a scanner to observe live data?


    Possible Causes
    start at purge valve -
    EVAP PURGE SOLENOID see diagram 12v on DB/BR KOEO
    EVAP PURGE SOLENOID VACUUM SUPPLY # 5 0r #6
    EVAP PURGE HOSE/TUBE AND FRESH AIR FILTER OBSTRUCTION

    second set of checks
    (Z910) GROUND CIRCUIT OPEN
    (K107) ESIM SIGNAL CIRCUIT OPEN
    EVAPORATIVE EMISSION LEAK
    EVAPORATIVE SYSTEM INTEGRITY MONITOR SWITCH
