Abstract: A vapor canister of an evaporative emissions (EVAP) system is configured to store fuel vapor evaporated from a liquid fuel housed in a fuel tank of a vehicle. A boost line is connected between a high-pressure side of a boost system of an engine and the vapor canister, a boost pressure control valve is disposed in-line along the boost line and configured to control an amount of boost pressure provided to the vapor canister, and a set of purge lines are connected between the vapor canister and at least one of the engine, an induction system of the engine, and an exhaust treatment system of the engine. A controller is configured to control the boost pressure control valve to control the boost pressure provided to the vapor canister to control an amount of fuel vapor forced from the vapor canister through at least one of the set of purge lines.

Abstract: A diagnostic system and method for a gasoline particulate filter (GPF) of an exhaust system of a vehicle comprise at least one heater associated with at least one oxygen (O2) sensor disposed proximate to the GPF in the exhaust system and a controller configured to determine a status of the GPF based on a duty cycle of the at least one O2 sensor heater and, based on the determined status of the GPF, detect a malfunction of the GPF or whether to regenerate the GPF.
