INSPECTION PROCEDURE

PROCEDURE


  1. INSPECT HARNESS AND CONNECTOR


    1. A0136IHE03

      Gasoline Engine:


      1. Disconnect the H2 fuel sender gauge connector.

      2. Check the meter indicator conditions.

        Result
        Wire Connection Condition Specified Condition
        2 - 3

        Short circuit

        (Ignition switch ON)

        Fuel gauge indicates F or more (Combination meter)

        Tech Tips

        This inspection creates an intentional short circuit between the connector terminals, to check the meter indicator operation.

        Note

        Perform the check quickly (within less than 10 seconds).

        Standard Voltage
        Tester Connection Condition Specified Condition
        3 - Body ground Ignition switch ON 4 to 7 V
      3. Measure the voltage.

      4. Reconnect the fuel sender gauge connector.

    2. A0136YAE01

      Diesel Engine:


      1. Disconnect the H24 fuel sender gauge connector.

      2. Check the meter indicator conditions.

        Result
        Wire Connection Condition Specified Condition
        1 - 2

        Short circuit

        (Ignition switch ON)

        Fuel gauge indicates F or more (Combination meter)

        Tech Tips

        This inspection creates an intentional short circuit between the connector terminals, to check the meter indicator operation.

        Note

        Perform the check quickly (within less than 10 seconds).

      3. Measure the voltage.

        Standard Voltage
        Tester Connection Condition Specified Condition
        2 - Body ground Ignition switch ON 4 to 7 V
      4. Reconnect the fuel sender gauge connector.

  2. INSPECT FUEL SENDER GAUGE ASSEMBLY


    1. Gasoline Engine:


      1. Remove the fuel sender gauge assembly.

        A013705E05
      2. Check that the float position is between E and F.

      3. Measure the resistance between terminals 2 and 3 of the fuel sender gauge connector.

        Standard Resistance
        Float Level Float Position [mm in.]) Specified Condition
        F 73.6 (2.9) to 78.6 (3.1) 12.0 Ω to 18.0 Ω
        1/2 1.3 (0.05) 199.0 Ω to 217.0 Ω
        Warning A 20.4 (0.80) 358.7 Ω to 386.7 Ω
        Warning B 10.4 (0.41) 376.4 Ω to 406.4 Ω
        E 76.3 (3.09) to 81.3 (3.11) 405.0 Ω to 415.0 Ω
      4. Reinstall the fuel sender gauge assembly.

    2. Diesel Engine:


      1. Disconnect the H24 fuel sender gauge connector.

      2. Measure the resistance between terminals 1 and 2 of the fuel sender gauge connector.

        Standard Resistance
        Float Level Fuel Quantity (liters [US qts, Imp, qts]) Specified Condition
        F 33.70 (35.61, 29.66) 35.0 Ω to 65.0 Ω
        1/2 17.50 (18.49, 15.40) 161.6 Ω to 191.6Ω
        Warning A 5.25 (5.55, 4.62) 273.0 Ω to 303.0 Ω
        Warning B 3.50 (3.70, 3.08) 293.0 Ω to 323.0 Ω
        E 0.38 (0.40, 0.33) 335.0 Ω to 365.0 Ω
      3. Reconnect the fuel sender gauge connector.

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

    A0137T6E03

    1. Gasoline Engine:


      1. Disconnect the C1 combination meter connector.

      2. Disconnect the H2 fuel sender gauge connector.

      3. Measure the resistance.

        Standard Resistance
        Tester Connection Specified Condition
        C1-14 - H2-2 Below 1 Ω
