2010 Nissan Sentra - P0455 Code

PO 455 code . put new fuel tank cap. Can not smell or see gas leaking from canister Have driven car almost 100 miles after new fuel cap and still showing SERVICE ENGINE SOON on dash.

there is probably a leak in the EVAP system. check the hoses for a leak

Service engine soon is different than the check engine light. Service engine soon usually means time to change the oil. Look in your owners manual for an explanation
