P0455 NISSAN - How do I fix it

Question

My 2005 Nissan Titan has a PO 455 EVAP emission control system leak (large) , how do I know what to replace?  Could it be the gas cap?

Answer 1

Try inspecting the vehicle for damage parts, broken EVAP canister or loose evaporator hoses. If there are no visual damage, you may start by replacing the gas cap and clearing the code.
