Abstract
A method of detecting a leak in an evaporative emissions system includes sealing an evaporative emissions system, achieving a first target pressure in the evaporative emissions system, achieving a second target pressure in the evaporative emissions system after achieving the first target pressure, and monitoring a system pressure subsequent to the second target pressure achieving step to determine a leak condition of the evaporative emissions system.
