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

  1. Disconnect the P9 connector.

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

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    H19-27 (L) - P9-2 (FS)
    		Always
    		Below 1 Ω
    H19-27 (L) - Body ground
    		Always
    		10 kΩ or higher
    H19-30 (FE) - P9-3 (FE)
    		Always
    		Below 1 Ω
    H19-30 (FE) - Body ground
    		Always
    		10 kΩ or higher

  1. Remove the fuel sender gauge assembly (Click here).

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

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

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    1 - 2
    		Float level is F (upper)
    		12 to 18 Ω
    1 - 2
    		Float level is between F (upper) and E (lower)
    		12 to 415 Ω (Gradually changes)
    1 - 2
    		Float level is E (lower)
    		405 to 415 Ω
