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.

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 ignition switch to ON.

(c) Turn the Techstream on.

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

(e) According to the display on the Techstream, perform the Active Test.

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 ignition switch to ON.

(c) Turn the Techstream on.

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

(e) According to the display on the Techstream, read the Data List.

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 SUCTION WITH PUMP AND GAUGE TUBE ASSEMBLY)

(a) Disconnect the D18 combination meter assembly connector.

(b) Disconnect the g2 fuel suction with pump and gauge tube assembly connector.

(c) 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 E and F.

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

Standard Resistance:





Result





C -- REPLACE FUEL SENDER GAUGE ASSEMBLY (for 1AR-FE) Removal

B -- REPLACE FUEL SENDER GAUGE ASSEMBLY (for 2GR-FE) Removal
A -- Continue to next step.

6. INSPECT FUEL SUCTION PUMP AND GAUGE TUBE ASSEMBLY

(a) Remove the fuel suction pump and gauge tube assembly Removal.





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

Standard Resistance:
