1. A method for diagnosing a leak of a fuel system in a vehicle, comprising:
determining, by a controller, whether an engine is actuated and a vehicle is thus driven as a monitoring condition for diagnosing the leak of the fuel system; and determining, by the controller, whether an additional monitoring condition for monitoring an outflow of the fuel system is satisfied in response to determining that the engine is actuated and an internal pressure of a fuel tank included in the fuel system is less than a target value, wherein the additional monitoring condition is a condition of preventing misdiagnosis of the leak in the fuel system due to disturbance while the vehicle is driven. |
