DESCRIPTION
FUEL RECEIVER GAUGE OPERATION
OPERATION
The combination meter assembly 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 receives fuel injection volume signals from the ECM and detects the voltage output from the fuel sender gauge assembly and operates the fuel receiver gauge.
FUEL RECEIVER GAUGE READING
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.
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.
Note
Add fuel with the ignition switch off to ensure safety and to enable refueling judgment so that an appropriate fuel receiver gauge reading will be obtained.
REFUELING JUDGMENT CONDITIONS
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.
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 ignition switch is ON, 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.
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 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.
The fuel sender gauge reading takes approximately 25 seconds 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 minute per 1 liter (1.1 US qts, 0.9 Imp. qts) to rise while the vehicle is being driven, and takes approximately 7 minutes per 1 liter (1.1 US qts, 0.9 Imp. qts) to rise while the vehicle is stopped.
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.

CAUTION / NOTICE / HINT
Note
When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.
Tech Tips
The fuel level warning light will come on when the fuel level is below 9.1 liters (9.6 US qts, 8.0 Imp. qts).

CHECK FUEL RECEIVER GAUGE OPERATION BY ADDING FUEL
Record the fuel receiver gauge reading.
If the fuel tank assembly is almost full, drain 20 liters (21.1 US qts, 17.6 Imp. qts) or more of fuel. (This is not necessary when the fuel tank assembly is sufficiently below full.)
Disconnect the cable from the negative (-) battery terminal to reset the fuel receiver gauge.

Check that the ignition switch is turned off before disconnecting the cable from the negative (-) battery terminal.
Connect the cable to the negative (-) battery terminal and turn the ignition switch to ON.
Check that the fuel receiver gauge has been reset.
Drive the vehicle at 1.8 km/h (1 mph) or more, then move the shift lever to P and turn the ignition switch off.
Add 5.0 liters (5.3 US qts, 4.4 Imp. qts) or more of fuel, turn the ignition switch to ON, and check that the fuel receiver gauge reading increases in proportion to the amount of fuel added.
