Inspection [01/2017 - ]: Procedure

  1. INSPECT FUEL SENDER GAUGE ASSEMBLY 
    1. Check the fuel sender gauge assembly output voltage.
      1. Apply 5 V between terminals 1 (FV) and 2 (FE).

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

        (Fuel Sender Gauge Assembly)

        Standard Voltage

        Tester Connection Condition Specified Condition
        2 (FE) - 3 (FR) Float position is F (upper) 4.255 to 4.605 V*
        Float position is E (lower) 0.345 to 0.695 V*
        1. *: The output voltage changes depending on the voltage applied to the terminals.

        HINT: 

        • Output voltage(F) = (0.851 x Voltage applied to terminals) to (0.921 x Voltage applied to terminals)
        • Output voltage(E) = (0.069 x Voltage applied to terminals) to (0.139 x Voltage applied to terminals)

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

  2. INSPECT NO. 2 FUEL SENDER GAUGE ASSEMBLY 
    1. Check the No. 2 fuel sender gauge assembly output voltage.
      1. Apply 5 V between terminals 1 (FV) and 2 (FE).

        *a Component without harness connected
        (No. 2 Fuel Sender Gauge Assembly)
        *b Voltage applied between terminals
        NOTE:
        • Be careful when connecting the leads, as the No. 2 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.
