P0456 Evap Leak Very Small 2001 – 2011 Caravans and Town and Country
The most common cause of this code in this vehicle is easy to fix. In the front of the engine compartment on the passenger’s side is the Evap solenoid. There are two rubber hoses (maybe 3 inches each) that link formed plastic line to the solenoid. This rubber breaks down and cracks. This code can be fixed if this is the case by replacing these rubber hoses with 5/16th bulk transmission cooler or fuel line. DO NOT break the plastic because Chrysler only sells the solenoid and all attached hoses and lines as a kit.

Just another quick tip. The Dodge trucks from the late 90’s to a few years ago had a similar issue. The E.V.A.P. canister is hidden under the air box or fuse panel depending on application and the hoses are prone to cracking and setting off codes. They made the hose molded into a tight U shape and replacing this with a longer hose will fix the issue. It won’t look as pretty but it will save the headache of ordering the factory replacement and doing it over every few years.
