    OK → See step   5 

  3. CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - FUEL SENDER GAUGE ASSEMBLY) 
    1. Disconnect the P9 connector.
    2. 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

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

  4. INSPECT FUEL SENDER GAUGE ASSEMBLY 
    1. Remove the fuel sender gauge assembly. Refer to REMOVAL .
