METER / GAUGE SYSTEM Fuel Receiver Gauge Malfunction

DESCRIPTION

The fuel sender gauge assembly has a variable resistance mechanism. The resistance decreases when the fuel amount increases, and the resistance increases when the fuel amount decreases. The fuel receiver gauge changes based on the resistance of the fuel sender gauge assembly.

      Disconnect the D66 combination meter assembly connector.

    2. Disconnect the G24 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
      D66-37 (L) - G24-2 (FS) Always Below 1 Ω
      D66-24 (E) - G24-3 (FE) Always Below 1 Ω
      D66-21 (ET) - Body ground Always Below 1 Ω
      D66-37 (L) or G24-2 (FS) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  3. INSPECT FUEL SUCTION WITH PUMP ASSEMBLY
