Fuel Receiver Gauge Malfunction: Procedure

  1. PERFORM ACTIVE TEST USING TECHSTREAM (FUEL METER OPERATION) 
    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to the ON position.
    3. Turn the Techstream on.
    4. Enter following menus: Body Electrical / Combination Meter / Active Test.
    5. Check the operation by referring to the table below.
      COMBINATION METER:

      Tester Display Test Part Control Range Diagnostic Note
      Fuel Meter Operation Fuel receiver gauge EMPTY, 1/2, FULL -

      OK

      Needle indication is normal.

    NG → REPLACE COMBINATION METER ASSEMBLY 

    OK: Go to next step 

  2. READ VALUE USING TECHSTREAM (FUEL INPUT) 
    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to the ON position.
    3. Turn the Techstream on.
    4. Enter following menus: Body Electrical / Combination Meter / Data List.
    5. Check the values by referring to the table below.
      COMBINATION METER:

      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      Fuel Input Fuel input signal Min.: 0, Max.: 255 Fuel gauge indicates (F): 48
      Fuel gauge indicates (3/4): 93
      Fuel gauge indicates (1/2): 148
      Fuel gauge indicates (3/4): 188
      Fuel gauge indicates (E): 206      		 -

      OK

      Fuel value signal displayed on the tester is almost the same as needle indication.

    NG → See step   3 

    OK → REPLACE COMBINATION METER ASSEMBLY 

  3. INSPECT FUEL SENDER GAUGE ASSEMBLY 
    1. Remove the fuel sender gauge assembly.

    2. Check that the float moves smoothly between E and F.
    3. Measure the resistance between terminal 2 and 3 according to the value(s) in the table below.

      OK

      Float level Resistance (Ω)
      F 3.0 to 5.0
      E 109.0 to 111.0

    NG → REPLACE FUEL SENDER GAUGE ASSEMBLY 

    OK: Go to next step 

  4. CHECK HARNESS AND CONNECTOR (COMBINATION METER - FUEL SENDER GAUGE) 
    1. Disconnect the C9 and F16 connectors.

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

      Standard resistance

      Tester Connection Condition Specified Condition
      C9-19 (FUEL SENDER) - F16-2 Always Below 1 Ω
      C9-2 (FE) - F16-3 Always Below 1 Ω
      C9-19 (FUEL SENDER) - Body ground Always 10 kΩ or higher
      C9-2 (FE) - Body ground Always 10 kΩ or higher

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

  5. REPLACE COMBINATION METER ASSEMBLY 
    1. Replace the combination meter assembly with a new or normal one.

      OK

      The operation of the combination meter assembly returns to normal.

    NG → REPLACE ECM 

    OK → END
