    		Condition
    		Specified Condition
    1 (-) - 2 (+)
    		Float level is F (upper)
    		161 to 169 Ω
    Float level is E (lower)
    		405 to 415 Ω

4.CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - FUEL SENDER GAUGE ASSEMBLY)


    E159545E01

  1. Disconnect the D1 combination meter assembly connector.

  1. Disconnect the L2 fuel sender gauge assembly connector.

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

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    D1-3 (L) - L2-1 (FS)
    		Always
    		Below 1 Ω
    D1-3 (L) or L2-1 (FS) - Body ground
    		Always
    		10 kΩ or higher
    D1-8 (FUS-) - L2-2 (FE)
    		Always
    		Below 1 Ω
    D1-8 (FUS-) or L2-2 (FE) - Body ground
    		Always
    		10 kΩ or higher
