Nissan Juke Service and Repair Manual : Fuel level sensor signal circuit
Component Function Check
2WD MODELS
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-69, "Removal and Installation".

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-69, "Removal and Installation".
Diagnosis Procedure
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-69, "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 terminal and fuel level sensor unit harness connector terminal.
*1: 2WD models
*2: 4WD models
4. Check continuity between combination meter harness connector terminal and ground.
Is the inspection result normal? YES >> GO TO 3.
NO >> Repair harness or connector.
3.CHECK FUEL LEVEL SENSOR GROUND CIRCUIT
Check continuity between fuel level sensor unit harness connector terminal and combination meter harness connector terminal.
*1: 2WD models
*2: 4WD models
Is the inspection result normal? YES >> INSPECTION END
NO >> Repair harness or connector.
