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?


Does monitor value match fuel gauge reading? YES >> INSPECTION END

NO >> Replace combination meter. Refer to MWI-69, "Removal and Installation".
