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 sub-assembly. The fuel sender gauge assembly has a variable resistor whose resistance changes according to the amount of fuel remaining. The fuel sender gauge assembly receives voltage from the combination meter assembly and changes 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 detects the voltage between the variable resistor and the resistor in the combination meter assembly, and operates the fuel receiver gauge.

FUEL RECEIVER GAUGE READING

During normal driving:

As the fuel level in the fuel tank sub-assembly changes when driving on a hill or applying the brakes, displaying the immediate output value from the fuel sender gauge assembly results in fluctuations in its reading. Therefore, an average output value from the fuel sender gauge assembly is displayed.

ii.

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.

REFUELING JUDGMENT CONDITIONS

NOTICE:: 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 (for CVT, Automatic Transaxle).

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.

ii.

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.

for Manual Transaxle: With the vehicle stopped, the fuel sender gauge assembly detects a change of 5.0 liters or more in the fuel level for 20 seconds or more continuously.

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 the fuel level is within such ranges.

ii.

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 minute per 1 liter to rise while the vehicle is being driven, and takes approximately 6 minutes per 1 liter to rise while the vehicle is stopped.

FORCED RESET OF FUEL RECEIVER GAUGE

When driving at 20 km/h (12 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 2 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.
