      *a Component without harness connected
      (Fuel Sender Gauge Assembly)
      *b Voltage applied between terminals
      1. 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).

        HINT: 

        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.

      Standard Resistance

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

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

      HINT: 

      • 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.
