What's the 7e8 engine code Hyundai Elantra?

This code flashes if there's a leak in the Evaporative Emission Control System of the Hyundai Elantra, particularly in the evaporative canister. However, this code is indicative of a small leak in the evaporative emission canister and not a large one. This emission control device or canister traps vapors from fuel evaporation and sends them to the fuel tank for later use. This prevents environmentally harmful vapors from entering the atmosphere and increases the fuel mileage of a tank of fuel. If there's a leak, the check engine light will illuminate. It is advisable to get it replaced fast, as leakage may be responsible for a fire hazard. The approximate cost of replacement is between $480 and $600.
