This code indicates a large leak in the EVAP system. First, try tightening the gas cap. If you are missing your gas cap, get a new one. If you've got a gas cap and it's tight, listen for a slight whoosh of air the next time you open it to fill up. Fuel disappearing from your tank leaves a slight vacuum of air behind, and if the cap is sealing well, then you should hear it. If you don't, install a new gas cap.

 

The EVAP system runs all the way from the fuel tank to the intake and back to the charcoal canister. A leak in any of these tubes or a failure in the charcoal canister will trigger a check-engine light and an EVAP code. The simplest way to track down an EVAP system failure is to shut the car off and start sniffing around the engine bay for a strong odor of fuel. If you smell any gasoline, at all, then you've got a leak in the EVAP system or lines.
