FUEL SENDER GAUGE ASSEMBLY INSPECTION

PROCEDURE


  1. INSPECT FUEL SENDER GAUGE ASSEMBLY


    1. Check the fuel sender gauge assembly output voltage.


      1. A01LGBSC01
        *a

        Component without harness connected

        (Fuel Sender Gauge Assembly)

        *b Voltage applied between terminals

        Apply 5 V between terminals 1 (FV) and 2 (FE).

        Note


        • Be careful when connecting the leads, as the fuel sender gauge assembly may be damaged if the leads are connected to the wrong terminals.

        • Do not apply more than 6 V to terminals 1 (FV) and 2 (FE).

        Tech Tips

        If a stable power supply is not available, use 4 1.2 V nickel-metal hydride batteries or equivalent.

      2. Measure the voltage according to the value(s) in the table below.

        A01LDR5C01
        *A for Long Wheelbase *B for Short Wheelbase
        *a

        Component without harness connected

        (Fuel Sender Gauge Assembly)

        - -
        Standard Voltage
        Tester Connection Condition Specified Condition
        2 (FE) - 3 (FR) Float position is F (upper) 4.25 to 4.61 V*
        Float position is E (lower) 0.34 to 0.70 V*

        • *: The output voltage changes depending on the voltage applied to the terminals.

        Tech Tips


        • Output voltage (F) = (0.850 x Voltage applied to terminals) to (0.922 x Voltage applied to terminals)

        • Output voltage (E) = (0.068 x Voltage applied to terminals) to (0.140 x Voltage applied to terminals)

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