Default Error Codes

Have a few codes showing up on the read-out and the engine light staying on, any ideas ?
She is a 2003, 1500, 4.7 Magnum, 2wd, auto, 56,000 miles.

Codes are;
PO456,
PO440,
PO441

All to do with EVAP I am guessing ?

Any way to check individual components, Solenoid, purge valve etc ?
All help, very gratefully received !

Cheers,

Alan..........

Sounds very much like the evap system. Sounds like you have a small leak somewhere. This may be a good thread to subscribe to:

has a lot of good information as far as codes. Just a thought my friend.

If you check the 3rd Gen Ram FAQ section, you'll find a detailed description of all error codes as well as a diagram of the evap system...
