FUEL LEVEL SENSOR SIGNAL CIRCUIT
DescriptionINFOID:0000000009461718
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:0000000009461719
1.COMBINATION METER INPUT SIGNAL
1. Select METER/M&A on CONSULT.
2. Using FUEL METER of DATA MONITOR, compare the value of DATA MONITOR with fuel gauge pointer
of combination meter.
Does the data monitor value approxim ately match the fuel gauge indication?
YES >> Inspection End.
NO >> Replace combination meter. Refer to MWI-82, "Removal and Installation"
.
Diagnosis ProcedureINFOID:0000000009461720
Regarding Wiring Diagram information, refer to MWI-32, "Wiring Diagram".
1.CHECK HARNESS CONNECTOR
1. Turn ignition switch OFF.
2. Check combination meter and fuel level sensor uni t 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 M24 and fuel level sensor unit harness connector B42.
2. Check continuity between combination meter harne ss connector M24 and fuel level sensor unit and fuel
pump harness connector B42.
3. Check continuity between fuel level sens or unit and fuel pump harness connector and ground.
Is the inspection result normal?
YES >> GO TO 3.

1. Check continuity between combination meter harnes s connector M24 and fuel level sensor unit and fuel
pump harness connector B42.
2. Check continuity between fuel level sens or unit and fuel pump harness connector and ground.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Repair or replace harness or connectors.
4.CHECK INSTALLATION CONDITION
Check fuel level sensor unit installation, and check whether the float arm interferes or binds with any of the
internal components in the fuel tank.
Is the inspection result normal?
YES >> Inspection End.
NO >> Install the fuel level sensor unit properly. Refer to FL-6, "Removal and Installation"
.
