ABSTRACT:
In an engine of a vehicle provided with a normally-closed solenoid valve in a fresh air induction port of a canister, in the case where a refueling cap is open when the engine is stopped, a control module operates in a usual-power consumption mode, and forces closing of the solenoid valve. In the case where the refueling cap is closed, the control mode shifts to a low-power consumption mode, and maintains the solenoid valve in the closed condition.
