Well i got an 03' 2 door hemi ram. Probably the first one they sold in 2003 when they got the first 2 hemi 2 doors in. I've had problems with the (evap sys perf) code PO440 and PO446 (evap emmisions vent valve perf. I changed the gas cap like a week ago and light is still on. Dodge changed the (solenoid) whatever solenoid that is like 20k miles ago when it was PO441 (evap purge flow monitor). I'm not sure and I haven't gone under the truck and looked but made I have a "hose loose". It's a great truck, at 51kmiles I havent had any other problems. Anyone had the same problem?

 

any suggestions before I bring her back to dodge for service?

 

It is leaking pressure somewhere. Hard to tell without a smoke test.
