P0457 Code - EVAP Control System Leak Detected Fuel Filler Cap Loose/Off

What Does P0457 Mean?

Code P0457 stands for Evaporative Emission System Leak Detected (Fuel Cap Loose/Off).

The evaporative emissions (EVAP) system is designed to prevent hydrocarbons (fuel vapors) from escaping into atmosphere. When hydrocarbons mix with sunlight and nitrogen oxides they form smog. To prevent this, the EVAP system stores the hydrocarbons in a canister. Then, when the time is right, the hydrocarbons are pulled into the engine and burned.
