Abstract: A refilling system for a vehicle including a body panel having a fixed opening, an adjustable refilling assembly partially enclosed by the body panel, the adjustable refilling assembly including a first port and a second port, the adjustable refilling assembly movable between at least a first configuration in which the first port is aligned with the fixed opening and a second configuration in which the second port is aligned with the fixed opening.

Abstract: A system for diagnosing an exhaust temperature sensor in an engine exhaust, the exhaust further including an emission control device, the system comprising an exhaust temperature sensor disposed in the exhaust pathway for indicating temperature; an air/fuel ratio sensor having a heater, the air/fuel ratio sensor disposed in the exhaust pathway; and a control system, the control system enabling and disabling the air/fuel ratio sensor heater based on operating conditions, the controller further adjusting fuel injection to provide a desired air-fuel ratio based on feedback from the air/fuel ratio sensor when the heater is enabled, and determining degradation of the exhaust temperature sensor based on a signal from the air/fuel ratio sensor when the heater is disabled.
