FUEL LEVEL SENSOR SIGNAL CIRCUIT
DescriptionINFOID:0000000012432576
The fuel level sensor unit and fuel pump detects the approx imate fuel level in the fuel tank and transmits the
fuel level signal to the combination meter.
Component Function CheckINFOID:0000000012432577
1.COMBINATION METER INPUT SIGNAL
1. Select METER/M&A on CONSULT.
2. Using FUEL METER of DATA MONITOR, compare the DATA MONITOR value with the fuel gauge posi- tion.
Does monitor value match fuel gauge reading?
YES >> Inspection End.
NO >> Replace combination meter. Refer to MWI-54, "
Removal and Installation".
Diagnosis ProcedureINFOID:0000000012432578
Regarding Wiring Diagram information, refer to MWI-26, "Wiring Diagram".
1.CHECK HARNESS CONNECTOR
1. Turn ignition switch OFF.
2. Check combination meter and fuel level sensor unit terminals (meter-side and harness-side) for poor con- nection.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace terminals or connectors.
2.CHECK FUEL LEVEL SENSOR UNIT CIRCUIT
1. Disconnect combination meter harness connector M82 and fuel level sensor unit and fuel pump harness
connector B44.
2. Check continuity between combination meter harness connector M82 terminal 6 and fuel level sensor unit
and fuel pump harness connector B44 terminal 2.
3. Check continuity between fuel level sensor unit and fuel pump harness connector B44 terminal 2 and ground.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair harness or connector.

3.CHECK FUEL LEVEL SENSOR GROUND CIRCUIT
1. Disconnect ECM connector F11.
2. Check continuity between combination meter har ness connector M82 terminal 24 and fuel level sensor
unit and fuel pump harness connector B44 terminal 5.
3. Check continuity between fuel level sensor unit and fuel pump harness connector B44 terminal 5 and ground.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Repair harness or connector.
4.CHECK INSTALLATION CONDITION
Check fuel level sensor unit installation, and verify t he float arm does not interfere or bind with the internal
components in the fuel tank.
Is the inspection result normal?
YES >> Inspection End.
NO >> Install the fuel level sensor unit properly.
Component InspectionINFOID:0000000012432579
1.REMOVE FUEL LEVEL SENSOR UNIT
Remove the fuel level sensor unit. Refer to FL-6, "
Removal and Installation".
>> GO TO 2.
2.CHECK FUEL LEVEL SENSOR UNIT
Check the resistance between fuel level sensor unit and fuel pump.
*: When float rod is in contact with stopper.
Is inspection result OK?
YES >> Inspection End.
NO >> Replace fuel level sensor unit and fuel pump. Refer to
FL-6, "
Removal and Installation".

Component Function Check".
Does monitor value match fuel gauge reading?
YES >> GO TO 2.
NO >> Replace combination meter. Refer to MWI-54, "
Removal and Installation".
2.CHECK FUEL LEVEL SENSOR SIGNAL CIRCUIT
Check the fuel level sensor signal circuit. Refer to MWI-45, "
DiagnosisProcedure".
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair harness or connector.
3.COMPONENT INSPECTION
Perform a component inspection on the fuel level sensor unit. Refer to MWI-46, "
Component Inspection".
Is the inspection result normal?
YES >> GO TO 4.
NO >> Replace fuel level sensor unit. Refer to FL-6, "
Removal and Installation".
4.CHECK FLOAT INTERFERENCE
Check that the float arm does not interfere or bind with components in the fuel tank.
Is the inspection result normal?
YES >> Replace combination meter. Refer to MWI-54, "Removal and Installation".
NO >> Repair or replace malfunctioning parts.
