FUEL LEVEL SENSOR SIGNAL CIRCUIT
Component Function Check
INFOID:0000000005883898
1.
CHECK COMBINATION METER OUTPUT 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. Refer to
MWI-51, "Removal and Installation"
Diagnosis Procedure
INFOID:0000000005883899
1.
CHECK COMBINATION METER INPUT SIGNAL
1.
Turn ignition switch ON.
2.
Check voltage between combination meter harness connector and ground.
Does it match fuel gauge reading?
YES
>> GO TO 2.
NO
>> Replace the combination meter. Refer to
MWI-51, "Removal and Installation"
.
2.
CHECK FUEL LEVEL SENSOR CIRCUIT
1.
Turn ignition switch OFF.
2.
Disconnect combination meter connector and fuel level sensor unit connector.
3.
Check continuity between combination meter harness connector and fuel level sensor unit harness con-
nector.
4.
Check continuity between combination meter harness connector and ground.
