Abstract: A fuel system for a motor vehicle includes a fuel pump having a first pump outlet connectable to an engine fuel inlet and a second pump outlet, a fuel pump module including an internal volume, a fuel pump module outlet is arranged in the internal volume fluidically connected to the second pump outlet, and a fuel valve is fluidically connected to the second pump outlet. The fuel valve is operable to fluidically isolate the fuel pump from the fuel pump module when fuel in the internal volume reaches a selected fuel level.

Abstract: An exhaust gas treatment system includes a particulate filter to collect particulate matter from exhaust gas flowing therethrough. The particulate filter realizes a pressure thereacross in response to the exhaust gas flow. A delta pressure sensor determines a first pressure upstream from the particulate filter and a second pressure downstream from the particulate filter. A delta pressure module is in electrical communication with the delta pressure sensor. The delta pressure module determines a pressure differential value based on a difference between the first pressure and the second pressure and generates a diagnostic signal based on a plurality of the pressure differential values and a predetermined time period.

Abstract: A gasoline Reid vapor pressure (RVP) detection system includes a fuel pump and a motor operating the fuel pump in a forward direction of rotation to feed a gasoline fuel to a vehicle engine. A control device is in communication with the motor selectively directing change from the forward direction of rotation to a reverse direction of rotation opposite to the forward direction of rotation. A pressure reduction device receives flow of the fuel during operation in the reverse direction of rotation and reduces a pressure of the fuel until fuel vaporization occurs. A pump speed at which vaporization of the fuel occurs at the pressure reduction device when a motor speed and a motor current change non-linearly is correlated to a fuel RVP.
