EVAP SYSTEM - evaporative emissions . There is a charcoal canister under the vehicle near the fuel tank that stores fuel vapors, instead of letting them vent to the atmosphere .The system has a vent solenoid that the PCM commands closed to do leak tests . It is normally open to allow air to be displaced by fuel when fueling . It's probably stuck closed !
