I took my truck to get inspected but it did not pass. They informed me that the code that apppeared was P0456. My check engine light is on. I have a 2005 Dodge Ram Quad Cab with a 4.7 Magnum engine. Any help would be greatly appreciated.

 

Small evap leak code. Check gas cap, may want to replace for good measure. Check evap canister for rotten lines. Or the fastest way is have it smoke checked. Smoke check will cost you.
