      1. Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        1 - 2 Float at upper end position Below 1 Ω
        Float at lower end position 10 kΩ or higher

        If the result is not as specified, replace the fuel filter assembly.

    2. Inspect the fuel heater.
