description Methods and systems are provided herein for a dust box cleanout routine of an evaporative emissions control (EVAP) system of a vehicle. In one example, a method is provided for an engine of a vehicle, comprising, during travel on an unpaved road, selectively discharging a dust box housed in a vent line of an evaporative emissions control (EVAP) system by opening a discharge valve of the dust box leading to atmosphere. In this way, an accumulation of dust on the air filter and in the dust box of the EVAP system may be reduced, thereby maintaining an efficiency of the EVAP system.
