Fuel Receiver Gauge Malfunction |
DESCRIPTION
FUEL RECEIVER GAUGE OPERATION
(a) 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 consumption 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
(a) During normal driving:
While driving, the fuel level indicated by the fuel receiver gauge decreases according to the fuel consumed. As the fuel level in the fuel tank may be unstable depending on the driving conditions, the combination meter assembly corrects the fuel receiver gauge reading based on the fluctuations in the fuel level.
(b) During refueling:
When fuel is added to the fuel tank, if the fuel level increases by a certain amount or more, the output of the fuel sender gauge assembly will change. The combination meter assembly detects this change and determines that refueling has been performed and calculates the volume of fuel added. This is called refueling judgment. The combination meter assembly adjusts the fuel receiver gauge reading based on the refueling judgment.
NOTICE:
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
(a) 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.
(b) Other judgment conditions (When other refueling method is used)
With the ignition switch ON, the vehicle and engine stopped, 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.
PRECAUTION FOR REFUELING
(a) The fuel sender gauge assembly cannot detect changes in the fuel level within certain ranges (around points E and F). Therefore, even if the refueling judgment conditions are satisfied, the fuel receiver gauge reading may not change when the fuel level is within either range.
(b) When refueling judgment is performed, it takes up to approximately 25 seconds for the fuel receiver gauge reading to change to the appropriate level.
FORCED RESET OF FUEL RECEIVER GAUGE
When refueling judgment conditions are not met, if the output of the fuel sender gauge assembly and the fuel receiver gauge reading differ by 15.0 liters (15.9 US qts, 13.2 Imp. qts) or more for approximately 5 minutes continuously, the fuel receiver gauge reading will reflect the detected fuel level without correction and it may take up to approximately 25 seconds for the reading to change to the appropriate level.
CAUTION / NOTICE / HINT
NOTICE:
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.
HINT:
The fuel level warning light will come on when the fuel level is below 7.5 liters (7.9 US qts, 6.6 Imp. qts).
