METER / GAUGE SYSTEM Fuel Receiver Gauge Display Malfunction

DESCRIPTION


  1. FUEL RECEIVER GAUGE OPERATION


    1. OPERATION

      The combination meter assembly (meter circuit plate) uses the fuel sender gauge assembly to detect the amount of fuel remaining in the fuel tank assembly. The Hall IC built into the fuel sender gauge assembly changes the output voltage according to the amount of fuel remaining. The combination meter assembly (meter circuit plate) detects the voltage output from the fuel sender gauge assembly and operates the fuel receiver gauge.

  2. FUEL RECEIVER GAUGE READING


    1. During normal driving:

      As the fuel level in the fuel tank assembly changes when driving on a hill or applying the brakes, the fuel receiver gauge reading is updated according to the fuel injection volume during normal driving. However, as the fuel injection volume measurement has a margin of error, the value is indicated after correction by input values from the fuel sender gauge assembly.

    2. During refueling:

      The fuel level in the fuel tank assembly rises rapidly when fuel is added. If the averaging process that is used during normal driving is used in this case, the fuel receiver gauge reading cannot be updated promptly. Therefore, when it is judged that fuel is being added to the vehicle based on the changes in the fuel level, output values from the fuel sender gauge assembly is immediately reflected in the fuel receiver gauge reading. This control is called refueling judgment.

  3. Note

    Add fuel with the power switch off to ensure safety and to enable refueling judgment so that an appropriate fuel receiver gauge reading will be obtained.

    REFUELING JUDGMENT CONDITIONS


    1. Normal judgment condition (When normal refueling method is used)

      With the power switch off, the fuel sender gauge assembly detects a change of 5.0 liters (5.3 US qts, 4.4 Imp. qts) or more in the fuel level.

    2. Other judgment conditions (When other refueling method is used)

      Any of the following conditions is met:


      • With the vehicle and engine stopped and the power switch on (IG) or on (READY), the fuel sender gauge assembly detects a change of 5.0 liters (5.3 US qts, 4.4 Imp. qts) or more in the fuel level.

      • With the vehicle stopped, the power switch is on (READY), the fuel sender gauge assembly detects a change of 15.0 liters (15.9 US qts, 13.2 Imp. qts) or more in the fuel level.

  4. PRECAUTION FOR REFUELING


    1. The fuel sender gauge assembly cannot detect changes in the fuel level within certain ranges (around points E and F). Therefore, even if 5.0 liters (5.3 US qts, 4.4 Imp. qts) or more of fuel is added, refueling judgment may not be performed and the fuel receiver gauge reading may not change when fuel level is within such ranges.

    2. The fuel sender gauge reading takes approximately 1 minute to rise from point E to F. If the vehicle is driven while the fuel sender gauge reading is rising, the fuel sender gauge reading will stop rising. After the fuel sender gauge reading stops rising, normal fuel sender gauge reading operation begins. The fuel sender gauge reading takes approximately 1.6 minutes per 1 liter (1.1 US qts, 0.9 Imp. qts) to rise while the vehicle is being driven, and takes approximately 5 minutes per 1 liter (1.1 US qts, 0.9 Imp. qts) to rise while the vehicle is stopped.

  5. FORCED RESET OF FUEL RECEIVER GAUGE

    When driving at a vehicle speed of 1.8 km/h (1 mph) or more, if the output value from the fuel sender gauge assembly is different from the fuel receiver gauge reading by 15.0 liters (15.9 US qts, 13.2 Imp. qts) or more for approximately 5 minutes, the output value from the fuel sender gauge assembly is immediately reflected in the fuel receiver gauge reading to compensate for a situation when refueling judgment cannot be made.

  6. PRECAUTION FOR DISCONNECTING CABLE FROM NEGATIVE (-) AUXILIARY BATTERY TERMINAL (w/ Canister Pump Module)


    1. Disconnect and reconnect the cable to the negative (-) auxiliary battery terminal and then open and close the fuel lid before turning the power switch on (IG) to increase the accuracy of the fuel receiver gauge.

      Tech Tips

      w/ Canister Pump Module: The accuracy of the fuel receiver gauge changes depending on fuel tank deformation caused by internal pressure. Before turning the power switch on (IG), equalizing the fuel tank pressure with the ambient air pressure by opening and closing the fuel lid after disconnecting and reconnecting the cable to the negative (-) auxiliary battery terminal increases the accuracy of the fuel receiver gauge.

The fuel level warning light will come on when the fuel level is below 6.4 liters (6.8 US qts, 5.6 Imp. qts).
