Abstract
Disclosed is an evaporated fuel treatment device that includes a sealing valve installed between a fuel tank and a canister, a pump module pressure sensor for detecting the pressure on the canister side pressure, and a tank internal pressure sensor for detecting a tank internal pressure. Upon detection of a significant difference between the canister side pressure and tank internal pressure, the device concludes that no open failure exists in the sealing valve.
