Methods and systems are provided for diagnosing a restriction of a fuel vapor canister. In one example, a method may include diagnosing restriction of a canister filter responsive to a first rate of decay of pressure of the canister to a target pressure being less than a first threshold rate of decay, when evacuating the canister to the atmosphere, and a second rate of decay of a pressure of the evaporative emissions control system to a target pressure being greater than a second threshold rate of decay, when evacuating the canister to a fuel tank.
