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


    1. Disconnect the P9 fuel sender gauge assembly connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      H19-27 (L) - P9-2 (FS) Always Below 1 Ω
      H19-27 (L) - Body ground Always 10 kΩ or higher
      H19-30 (FE) - P9-3 (FE) Always Below 1 Ω
      H19-30 (FE) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

      (to Fuel Sender Gauge Assembly)

      Remove the fuel sender gauge assembly (See page for 2ZR-FXE, Click here for 5ZR-FXE).

    2. Check that the float moves smoothly between E and F.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - 2 Float level is F (upper) 13.5 to 16.5 Ω
      1 - 2 Float level is between F (upper) and E (lower) 13.5 to 414.5 Ω (Gradually changes)
      1 - 2 Float level is E (lower) 405.5 to 414.5 Ω
