<p>A first determiner determines whether a pressure in a fuel tank is within a predetermined range when an ignition switch of an engine is on. A second determiner determines whether a valve allows or prohibits a communication between the fuel tank and a switch valve, when the first determiner determines that the pressure in the fuel tank is within the predetermined range. A control unit controls a pressure controlling portion based on a determination result of the first determiner and a determination result of the second determiner. A leak determiner determines whether the fuel tank has a leak of evaporated fuel based on a signal output from a first detector detecting a pressure in a detection passage and a signal output from a second detector detecting a pressure in the fuel tank.</p> |
