METER / GAUGE SYSTEM Fuel Receiver Gauge Display Malfunction

DESCRIPTION


  1. OPERATION

    The combination meter assembly uses the fuel injection volume signal from the ECM and fuel sender gauge assembly to detect the amount of fuel remaining in the fuel tank sub-assembly. Each gauge assembly has a variable resistor whose resistance changes according to the amount of fuel remaining. The gauge assemblies receive voltage from the combination meter assembly and change the voltage based on the resistance that changes according to the amount of fuel remaining in the fuel tank sub-assembly. The combination meter assembly receives a fuel injection volume signal from the ECM and detects the voltage between each variable resistor and each resistor in the combination meter assembly, and operates the fuel receiver gauge.

  2. FUEL RECEIVER GAUGE READING


    1. During normal driving:

      As the fuel level in the fuel tank sub-assembly changes when driving on a hill or applying 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 sub-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 shift lever position and changes in the fuel level, output values from the fuel sender gauge assembly are immediately reflected in the fuel receiver gauge reading. This control is called refueling judgment.

  3. REFUELING JUDGMENT CONDITIONS

    Note

    Add fuel with the ignition switch off to ensure safety and to enable refueling judgment so that an appropriate fuel receiver gauge reading is obtained. If it is necessary to add fuel with the ignition switch ON, move the shift lever to P or N.


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

      With the ignition 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 ignition switch ON, 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 engine running, the ignition switch ON and the shift lever in P or N, 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 engine running, the ignition switch ON and the shift lever in any driving position, 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

    The fuel sender gauge assembly cannot detect changes in the fuel level within certain ranges (around points E and F). Therefore, even though 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.

  5. FORCED RESET OF FUEL RECEIVER GAUGE

    When driving at 20 km/h (12 mph) or more, if the output values from the fuel sender gauge assembly are different from the fuel receiver gauge reading by 15.0 liters (15.9 US qts, 13.2 Imp. qts) or more for approximately 2 minutes, output values from both gauge assemblies are immediately reflected in the fuel receiver gauge reading to compensate for a situation when refueling judgment cannot be made.
