Fuel Receiver Gauge Malfunction

METER / GAUGE / DISPLAY: METER / GAUGE SYSTEM: Fuel Receiver Gauge Malfunction
- Fuel Receiver Gauge Malfunction

DESCRIPTION

* The meter CPU uses the fuel sender gauge assembly to determine the level of the fuel in the fuel tank. The resistance of the fuel sender gauge will vary between approximately 13.5 Ohms with the float at the full position, and 414.5 Ohms with the float at the empty position. The meter outputs battery voltage through two 820 Ohms resistors that are mounted in parallel inside the meter CPU. The meter CPU measures the voltage between the variable resistor in the fuel sender gauge and the two resistors mounted in parallel in the meter. Voltage measured at this point will vary as the float of the fuel sender gauge is moved. The highest voltage observed should be approximately half of the battery voltage.

NOTICE:
When the combination meter is removed or replaced, its connector is disconnected or fuel is added, the fuel receiver gauge display will return to normal a maximum of 16 minutes after the power switch is turned on (IG) or when vehicle speed is input.

HINT
The fuel level warning light will come on when the fuel level is below 10.1 liters (10.7 US qts, 8.9 Imp.qts).

INSPECTION PROCEDURE

PROCEDURE

1. CHECK CAN COMMUNICATION SYSTEM

(a) Check if a CAN communication DTC is output Diagnosis System.

Result:





B -- GO TO CAN COMMUNICATION SYSTEM How to Proceed With Troubleshooting
A -- Continue to next step.

2. PERFORM ACTIVE TEST USING TECHSTREAM (FUEL METER OPERATION)

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Turn the Techstream on.

(d) Enter following menus: Body Electrical / Combination Meter / Active Test.

(e) Check the operation by referring to the table below.

Combination Meter





OK:

Fuel receiver gauge indication is normal.

NG -- REPLACE COMBINATION METER ASSEMBLY Removal
OK -- Continue to next step.

3. READ VALUE USING TECHSTREAM (FUEL INPUT)

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Turn the Techstream on.

(d) Enter following menus: Body Electrical / Combination Meter / Data List.

(e) Check the values by referring to the table below.

Combination Meter





OK:

Fuel level signal displayed on the Techstream is almost the same as fuel receiver gauge indication.

NG -- REPLACE COMBINATION METER ASSEMBLY Removal
OK -- Continue to next step.

4. CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - FUEL SENDER GAUGE ASSEMBLY)

(a) Disconnect the F16 and j2 connectors.





(b) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

5. INSPECT FUEL SENDER GAUGE ASSEMBLY

(a) Remove the fuel sender gauge assembly Removal.





(b) Check that the float moves smoothly between F and E.

(c) Check if the fuel sender gauge arm is deformed.

(d) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

NG -- REPLACE FUEL SENDER GAUGE ASSEMBLY (for 2GR-FXE) Removal
OK -- Continue to next step.

6. CHECK FUEL SUCTION PUMP AND GAUGE ASSEMBLY

(a) Visually check for deformation on the fuel suction pump and gauge assembly connector.

OK:

There is no deformation.

NG -- REPLACE FUEL SUCTION PUMP AND GAUGE ASSEMBLY (for 2GR-FXE) Removal

OK -- REPLACE COMBINATION METER ASSEMBLY Removal
