    3. Measure the resistance between terminals 2 and 3 of the connector according to the value(s) in the table below.

      Standard resistance

      Float level Float position mm (in.) Resistance (Ω)
      F 88.6 (3.49) +- 3 (0.12) 4.0 +- 1
      1/2 6.4 (0.25) 59
      E 102.9 (4.05) +- 3 (0.12) 110.0 +- 2.5

    NG → REPLACE FUEL SENDER GAUGE ASSEMBLY 

    OK: Go to next step 

  2. CHECK HARNESS AND CONNECTOR (FUEL SENDER GAUGE - COMBINATION METER) 
    1. Disconnect the C9, C11and F5 connectors.
    2. Measure the resistance according to the value(s) in the table below.

      Standard resistance

      Tester connection Condition Specified condition
      C11-4 (FUEL (FR)) - F15-2 Always Below 1 Ω
      C9-10 (FUEL GND) - F15-3 Always Below 1 Ω

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK → REPLACE COMBINATION METER ASSEMBLY
