METER / GAUGE SYSTEM Fuel Receiver Gauge Malfunction

DESCRIPTION

The fuel sender gauge 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.

    1. Disconnect the D66 meter connector.

    2. Disconnect the G24 gauge 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)
      D66-21 (ET) - Body ground
      D66-37 (L) or G24-2 (FS) - Body ground Always 10 kΩ or higher

    NG
