PROCEDURE

  1. READ VALUE USING INTELLIGENT TESTER (FUEL SENDER GAUGE)

    1. Use the Data List to check if the fuel receiver gauge is operating properly (Click here).

      Table 1. Combination Meter

      Tester Display

      Measurement Item/Range

      Normal Condition

      Diagnostic Note

      Fuel Input

      Fuel sender gauge input/Min.: 0, Max.: 127.5

      Fuel sender gauge input value

      Unit: L

      OK

      Fuel amount value displayed on the intelligent tester is almost the same as needle indication.

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

    1. Disconnect the H62 combination meter assembly connector.

    2. Disconnect the N18 fuel suction with pump assembly connector.

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

      Standard Resistance

      Tester Connection

      Condition

      Specified Condition

      H62-37 (L) - N18-2 (FS)

      Always

      Below 1 Ω

      H62-21 (ET) - Body ground

      Always

      Below 1 Ω

      H62-37 (L) or N18-2 (FS) - Body ground

      Always

      10 kΩ or higher

      H62-24 (E) or N18-3 (FE) - Body ground

      Always

      10 kΩ or higher

    REPAIR OR REPLACE HARNESS OR CONNECTOR
