This indicates that part of the EVAP control system has malfunctioned. This system purges gas vapors from the fuel tank, stores them in a carbon canister, and then siphons them into the engine via intake vacuum to burn. Likely could be, damaged or leaky hoses, bad vacuum switch, faulty purge solenoid, or bad LDP (leak detection pump). Likely needs trained professional to check each possible item.
