Methods and systems are provided for preheating a fuel vapor storage canister in an evaporative emissions system prior to a vehicle start. In one example, a method may include learning common vehicle routes and identifying routes in which fuel vapor storage canister preheating is indicated, such as routes that will enable fuel vapors to be purged to an engine intake shortly after the vehicle start. Then, in anticipation of an identified route for fuel vapor storage canister preheating, a vehicle controller may be transitioned from a sleep mode to an awake mode prior to the vehicle start in order to commence a fuel vapor storage canister preheating routine.
