  1. Check that the float moves smoothly between F and E.

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

    Standard Resistance:

    Tester Connection
    		Float Level
    		Float Position (mm (in.))
    		Specified Condition
    1 - 2
    		F
    		142 to 152 (5.591 to 5.984)
    		13.5 to 16.5 Ω
    1/2
    		71.1 to 76.1 (2.799 to 2.996)
    		208.3 Ω
    Warning
    		5.9 to 10.9 (0.232 to 0.429)
    		365.2 Ω
    E
    		0 (0)
    		405.5 to 414.5 Ω

  1. Reinstall the fuel sender gauge assembly.

  1. Remove the fuel suction with pump and gauge tube assembly (YARIS_NCP93 RM000004NLO00FX_01_0009.html).

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

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    A-2 (FS) - B-2
    		Always
    		Below 1 Ω

5.CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - FUEL SUCTION WITH PUMP AND GAUGE TUBE ASSEMBLY)

  1. Disconnect the D100 combination meter assembly connector.

  1. Disconnect the J71 fuel suction with pump and gauge tube assembly connector.

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

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    D100-16 (L) - J71-2 (FS)
    		Always
    		Below 1 Ω
    D100-16 (L) - Body ground
    		Always
    		10 kΩ or higher
    J71-3 (FE) - Body ground
    		Always
    		Below 1 Ω

  1. Reconnect the fuel suction with pump and gauge tube assembly connector.

  1. Reconnect the combination meter assembly connector.
