Abstract
A method of managing the saturation level of a vapor collection canister for an on-board fuel vapor emission control system. The method includes flowing the fuel vapor through a canister flow path between a first port and a second port of the vapor collection canister, and signaling with a sensor the temperature of an adsorbent disposed in the canister flow path, the sensor being exposed to the adsorbent.
