c. Fuel Tank Internal Pressure is High
If the internal pressure in the fuel tank is high and the purge VSV is open, the THS ECU opens the fuel
vapor-containment valve in order to release the pressure from the fuel tank. At this time, the fuel vapor
that is absorbed in the canister is drawn inside the engine by intake vacuum and burned.
