FUEL LEVEL SENSOR SIGNAL CIRCUIT

FUEL LEVEL SENSOR SIGNAL CIRCUIT

2WD

2WD : Description

INFOID:0000000001110136

The fuel level sensor (main) detect the fuel level in the fuel tank and transmit the fuel level sensor signal to the
combination meter.

2WD : Component Function Check

INFOID:0000000001110137

1.

CHECK COMBINATION METER INPUT SIGNAL

Select the “Data Monitor” for the “METER/M&A” and compare the “FUEL METER” monitor value with the fuel
gauge reading on the combination meter.

Does monitor value match fuel gauge reading?

YES

>> INSPECTION END

NO

>> Replace combination meter.

2WD : Diagnosis Procedure

INFOID:0000000001110138

1.

CHECK COMBINATION METER INPUT SIGNAL

1.

Turn ignition switch ON.

2.

Check voltage between combination meter harness connector terminal 34 and ground.

Does it match fuel gauge reading?

YES

>> GO TO 2.

NO

>> Replace the combination meter.

2.

CHECK FUEL LEVEL SENSOR CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect combination meter connector and fuel level sensor unit (main) connector.

3.

Check continuity between combination meter harness connector terminal 34 and fuel level sensor unit
(main) harness connector terminal 4.

4.

Check continuity between combination meter harness connector terminal 34 and ground.

Is the inspection result normal?

YES

>> GO TO 3.

4WD

4WD : Description

INFOID:0000000001110735

The fuel level sensor (main) and the fuel level sensor (sub) detect the fuel level in the fuel tank and transmit
the fuel level sensor signal to the combination meter.

4WD : Component Function Check

INFOID:0000000001110736
