Abstract: Methods and systems are provided for adjusting and diagnosing a position of a fuel tank isolation valve (FTIV) of a fuel system. In one example, a method comprises adjusting a FTIV of a fuel system by sending an electrical pulse to the FTIV; and comparing a current draw of the FTIV to a known current draw profile to verify the position of the FTIV. In this way, the position of the FTIV may be diagnosed, thereby resulting in increased accuracy of subsequent valve control.

Abstract: Methods and systems for controlling and reducing current consumption of a vapor blocking valve are disclosed. In one example, current supplied to the vapor blocking valve is adjusted proportionately to fuel tank pressure to compensate for fuel tank pressure acting on the vapor blocking valve. Vapor blocking valve current is adjusted to reduce current consumption.

Abstract: A system includes a processor and an external fuel indicator. The processor is configured to instruct powering of a digital display in response to detection that one or more power-up indicators has been satisfied. The processor is also configured to obtain fuel-related readings as a vehicle is fueled. Also, the processor is further configured to determine at least one fuel-related statistic other than a current fuel level. Further, the processor is configured to output the at least one fuel-related statistic to the external fuel indicator.
