摘要:
A method (100,200) of sensing a reduction in fuel screen (22) area in a fuel system. The method includes detecting (102) an engine shutdown, initiating (112) an electronic engine control (EEC) built in test, shifting a metering valve from a first position to a second position, determining (212-216) a travel time of the metering valve, and sensing (118) a reduction in fuel screen area based on the travel time of the metering valve.
