Does anyone know what a P044.2 and P045.5 diagnostic code on a 2001 g.caravan means? I'm stationed in Korea and can't find anyone that knows how to read it out.
Thanks
Thanks

Check the hoses leading to the charcoal canister on the underside of the van. It is possible that one of the hoses has come loose or gotten caught on something that caused it to break. The gas cap issue usually will go away quickly. If you still have the problem then the hoses are probably the cause.
There is also a purge solenoid located under the hood that may have malfunctioned. Doubtful but you can check it to see if the vacuum lines are still good leading to the solenoid.
