    Abstract: Methods and systems are provided for adjusting a vehicle operation based on an output of a hydrocarbon sensor located in a canister vent line coupling a fuel vapor canister and the atmosphere in order to reduce exhaust and evaporative emissions, and improve fuel economy while providing improved cabin comfort. Specifically, in response to determining an ambient hydrocarbon amount greater than a threshold based on the hydrocarbon sensor output during purging, the purging operation may be terminated, and the canister may be sealed from the atmosphere. Further, in response to the determination, a vehicle climate control system may be adjusted to stop providing fresh air to the vehicle cabin and provide only cabin air recirculation, and an engine operation may be adjusted such that a ratio of a port fuel injection amount to a direct fuel injection amount is increased.
