I posted to the forum a while back about an engine light code 0456 & was told that i have an air leak in EVAP system. I would like to inspect hoses for holes/cracks. Where do i start & which hoses need to be inspected? Thanx 4 ur input

 

Hello,

Inspect the rubber hoses from the LDP valve which is in the engine bay. These transition to hard plastic in the vicinty of the engine, then turn back to rubber before going below the engine where they turn into aluminum tubing. These run back toward the fuel tank. Focus on the rubber hoses. There should only be 2 that would be suspect. Replace any that are cracked or split. Although I looked at them all, it was the hose directly above the battery that was split. It was about a 5 minute fix (once I bought the hose). Good luck hunting...
