    P0442 Evaporative Emission (EVAP) System Small Leak Detected (often this is a loose or bad gas cap!)
    0456 ?

    Did you fill up with gas and forget the cap due to financial shock?

    Small leak is rarely a gas cap problem. Most likely a cracked hose near the charcoal canister. Read this to understand how the EVAP system works.
