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


    1. Disconnect the R11 fuel suction tube with pump and gauge assembly connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      L23-14 (L) - R11-2 (FS) Always Below 1 Ω
      L23-14 (L) - Body ground Always 10 kΩ or higher
      L23-15 (ES 2) - R11-3 (FE) Always Below 1 Ω
      L23-15 (ES 2) - Body ground Always 10 kΩ or higher

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

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

      Standard Resistance
      Type A
      Tester Connection Condition Specified Condition
      1 - 2 Float level is F (upper) 13.5 to 16.5 Ω
      1 - 2 Float level is between F (upper) and E (lower) 13.5 to 414.5 Ω (Gradually changes)
      1 - 2 Float level is E (lower) 405.5 to 414.5 Ω
      Type B
      Tester Connection Condition Specified Condition
      1 - 2 Float level is F (upper) 12.0 to 18.0 Ω
      1 - 2 Float level is between F (upper) and E (lower) 12.0 to 415.0 Ω (Gradually changes)
      1 - 2 Float level is E (lower) 405.0 to 415.0 Ω
