摘要： If a pressure deviation ΔP (amount of pressure decrease) after a first predetermined time period T1 has elapsed since a bypass valve (canister opening/closing valve) is controlled from an opened to closed state by actuating a negative pressure pump when the engine is stopped and a purge valve is opened is less than a first predetermined pressure P1, it is determined that the bypass valve is in an open sticking state, and if the pressure deviation ΔP is not less than the first predetermined pressure P1, it is determined that the bypass valve is not in an open sticking state. Moreover, a pressure deviation ΔP after a second predetermined time T2 has elapsed since the bypass valve is subsequently controlled to be opened decreases by not less than a second predetermined pressure P2, it is determined that the bypass valve 37 is not in a closed sticking state.

摘要： An apparatus is provided for determining a failure in a thermostat that controls the flow of a coolant into a radiator in response to an actual water temperature of the coolant for an engine in a vehicle. The apparatus includes a detector that detects the actual water temperature; an estimator that calculates an estimated water temperature of the coolant; and a failure determining unit that compares the actual water temperature detected with the estimated water temperature calculated by the water temperature estimator under cold start of the engine and determines whether the thermostat is valve-open failure. In an engine nonoperating mode including at least automatic stop of the engine, the water temperature estimator applies a behavior of the actual water temperature to an estimated water temperature calculated immediately before automatic stop of the engine to calculate an estimated water temperature in the engine nonoperating mode.

摘要： A purge solenoid valve is opened to introduce an atmospheric pressure into a fuel tank, the purge solenoid valve is closed to operate a negative pressure pump, and set an internal pressure of the tank to a reference pressure Pb. Then, a changeover valve is closed, and the purge solenoid valve is opened to cause a canister to communicate with an intake passage. Further, the changeover valve is opened, and the purge solenoid valve is closed. Then, a first tank internal pressure Po is detected and subtracted from the reference pressure Pb. If a calculated first pressure deviation ΔPo is larger than a first threshold ΔP1, it is determined that there is no open sticking in a sealing valve.
