Nissan Maxima Service and Repair Manual: Fuel level sensor signal circuit

Description

The fuel level sensor unit and fuel pump (fuel level sensor) detects the approximate fuel level in the fuel tank and transmits the fuel level signal to the combination meter.

Component Function Check

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.

Diagnosis Procedure

Regarding Wiring Diagram information, refer to MWI-87, "Wiring Diagram".

1.CHECK HARNESS CONNECTOR

  1.  Turn ignition switch OFF.

  2.  Check combination meter and fuel level sensor unit and fuel pump (fuel level sensor) terminals (meterside and harness-side) for poor connection.

2.CHECK FUEL LEVEL SENSOR UNIT AND FUEL PUMP (FUEL LEVEL SENSOR) CIRCUIT

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

  2.  Check continuity between combination meter harness connector (A) and fuel level sensor unit and fuel pump (fuel level sensor) harness connector (B).

3. Check continuity between combination meter harness connector (A) and ground.

3.CHECK FUEL LEVEL SENSOR UNIT AND FUEL PUMP (FUEL LEVEL SENSOR) GROUND CIRCUIT

1. Check continuity between combination meter harness connector (A) and fuel level sensor unit and fuel pump (fuel level sensor) harness connector (B).

2. Check continuity between combination meter harness connector (A) and ground.

4.CHECK INSTALLATION CONDITION

Check fuel level sensor unit and fuel pump (fuel level sensor) installation, and check whether the float arm interferes or binds with any of the internal components in the fuel tank.

Component Inspection

1.REMOVE FUEL LEVEL SENSOR UNIT AND FUEL PUMP (FUEL LEVEL SENSOR)

Remove the fuel level sensor unit and fuel pump (fuel level sensor). Refer to FL-6, "Removal and Installation".
