I have a 2002 Dodge Durango that failed the emissions test, the error code is p0456. I changed the gas cap and tried once to reset the computer by disconnecting the battery. Someone suggested that an evaporator hose may be cracked or split. Does anyone know where these hoses are located? Thanks.

if you had an evaporator hose split you'd have an a/c problem not a check engine light! Read the posts for your codes and evap codes on Dodge then look under the hood at the vaccum schematic, find the service port with green port and trace the hoses through the circuits from there. If the gas cap is a parts store replacement it could still be responsible for the dtc.
