    END (TEMPORARY ERROR DUE TO FUEL RECEIVER GAUGE CHARACTERISTICS) 

    HINT: 

    It is suspected that the indicated value of the fuel receiver gauge did not automatically update due to the following reasons:

    • The amount of added fuel was less than the refueling judgement amount.
    • Refueling was performed in a range for which detection is not possible (indicated value of fuel receiver gauge was near E, F)

    Result: 

    B 

    See step  5

  5. CHECK FUEL RECEIVER GAUGE (OPERATION BY ADDING FUEL) 
    NOTE:

    As it is necessary to add more than a certain amount of fuel to the fuel tank, if the fuel level is near full, perform the following procedure then proceed to step (a). If the fuel tank is not near full, proceed to step (a) without performing the following procedure.

    1. Turn the ignition switch off.
    2. Remove 15 liters (15.9 US qts, 13.2 Imp. qts) or more of fuel from the fuel tank.
    3. Turn the ignition switch to ON.
    4. Wait 6 minutes or more.
    5. Confirm that the fuel receiver gauge indicates a value in accordance with the removed amount of fuel.
    1. Record the fuel receiver gauge reading.
    2. Turn the ignition switch off.
    3. Disconnect the cable from the negative (-) auxiliary battery terminal.

      HINT: 

      This resets the current fuel level information stored by the combination meter assembly.

    4. Wait 2 minutes or more.
    5. Connect the cable to the negative (-) auxiliary battery terminal.
    6. Turn the ignition switch to ON.
    7. Drive the vehicle at 2 km/h (1 mph) or more, and then stop the vehicle on a flat surface.
    8. Turn the ignition switch off.
    9. Wait 30 seconds or more.
    10. Add the following amount of fuel or more.
      1. 6.0 liters (6.3 US qts, 5.3 Imp. qts)
    11. Turn the ignition switch to ON.
    12. Check that the fuel receiver gauge reading increases in proportion to the amount of fuel added.
      NOTE:

      After turning the ignition switch to ON, it may take approximately 30 seconds until the fuel receiver gauge indicates the determined value.

      Result

      Result Proceed to
      Fuel receiver gauge reading increases in proportion to the amount of fuel added A
      Fuel receiver gauge reading does not change even when fuel is added B

    Result: 

    A 

    See step  8

    Result: 

    B 

    REPLACE COMBINATION METER ASSEMBLY 

    Refer to REMOVAL [11/2022 - 09/2024] , or refer to REMOVAL [09/2024 - ]

  6. CHECK FOR DTC (SFI SYSTEM) 
    1. Check if SFI system DTCs are output.

      Powertrain > Engine > Trouble Codes 

      Result

      Result Proceed to
      DTCs are not output A
      DTCs are output B

    Result: 

    B 

    GO TO SFI SYSTEM 

    Refer to DIAGNOSTIC TROUBLE CODE CHART [09/2022 - 09/2024] , or refer to DIAGNOSTIC TROUBLE CODE CHART [09/2024 - ]

    Result: 

    A 

    See step  7

  7. CHECK FUEL RECEIVER GAUGE 
    1. Record the fuel receiver gauge reading.
    2. Turn the ignition switch off.
    3. Disconnect the cable from the negative (-) auxiliary battery terminal.

      HINT: 

      This resets the current fuel level information stored by the combination meter assembly.

    4. Wait 2 minutes or more.
    5. Connect the cable to the negative (-) auxiliary battery terminal.
    6. Wait 30 seconds or more.
    7. Turn the ignition switch to ON.
    8. Check if the fuel receiver gauge reading corresponds with the amount of fuel remaining in the fuel tank.
      NOTE:

      After turning the ignition switch to ON, it may take approximately 30 seconds until the fuel receiver gauge indicates the determined value.

      Result

      Result Proceed to
      Fuel receiver gauge reading corresponds with the amount of fuel remaining in the fuel tank A
      Fuel receiver gauge reading does not correspond with the amount of fuel remaining in the fuel tank B

    Result: 

    A 

    See step  8

    Result: 

    B 

    REPLACE COMBINATION METER ASSEMBLY 

    Refer to REMOVAL [11/2022 - 09/2024] , or refer to REMOVAL [09/2024 - ]

  8. INSPECT FUEL TANK SUB-ASSEMBLY 

    HINT: 

    Inspect the fuel tank sub-assembly, fuel sender gauge assembly and No. 2 fuel sender gauge assembly for deformation, foreign matter or an improperly installed fuel receiver gauge, as this may be the cause of the fuel receiver gauge malfunction.

    1. Visually check the fuel tank sub-assembly for any abnormalities.
    2. Check if there is an excessive amount of foreign matter in the fuel tank sub-assembly.
    3. Visually check the fuel sender gauge assembly and No. 2 fuel sender gauge assembly for damage and confirm that it operates correctly.
    4. Check the installation condition of the fuel tank sub-assembly, fuel sender gauge assembly and No. 2 fuel sender gauge assembly.

      Result

      Result Proceed to
      Normal A
      Appearance of the fuel tank sub-assembly is abnormal B
      There is an excessive amount of foreign matter in the fuel tank sub-assembly C
      The fuel sender gauge assembly or No. 2 fuel sender gauge assembly is visually damaged or does not operate correctly D
      The fuel tank sub-assembly, fuel sender gauge assembly or No. 2 fuel sender gauge assembly is not installed correctly E
