  "textContent": "A method for an engine is presented, wherein purge air is routed through a fuel vapor canister during a first condition such that desorbed fuel vapor traverses a canister purge port en route to an engine intake, and wherein purge air is routed through a fuel vapor canister during a second condition such that desorbed fuel vapor traverses a canister load port en route to the engine intake. Bypassing the canister purge port during a canister purge event allows for cleaning adsorbed fuel vapor from the canister even if flow through the canister purge port is restricted. In this way, vehicle emissions may be mitigated during conditions where a carbon dust filter at the canister load port is clogged.",
