Nissan Versa (N17): P0461 fuel level sensor

DTC Logic

DTC DETECTION LOGIC

NOTE:

  • If DTC P0461 is displayed with DTC UXXXX, first perform the trouble diagnosis for DTC UXXXX.
  • If DTC P0461 is displayed with DTC P0607, first perform the trouble diagnosis for DTC P0607. Refer to EC, "DTC Logic".

Driving long distances naturally affect fuel gauge level.

This diagnosis detects the fuel gauge malfunction of the gauge not moving even after a long distance has been driven.

DTC No. Trouble diagnosis name DTC detecting condition Possible cause
P0461 FUEL LEVEL SENSOR (Fuel level sensor circuit range/ performance) The output signal of the fuel level sensor does not change within the specified range even though the vehicle has been driven a long distance.
  • Harness or connectors (The CAN communication line is open or shorted)
  • Harness or connectors (The sensor circuit is open or shorted)
  • Combination meter
  • Fuel level sensor

DTC CONFIRMATION PROCEDURE

1.PERFORM COMPONENT FUNCTION CHECK

Perform component function check. Refer to EC, "Component Function Check".

Use component function check to check the overall function of the fuel level sensor function. During this check, a 1st trip DTC might not be confirmed.

Is the inspection result normal?

YES >> INSPECTION END

NO >> Proceed to EC, "Diagnosis Procedure".

Component Function Check

1.PRECONDITIONING

WARNING: When performing following procedure, be sure to observe the handling of the fuel. Refer to FL, "General Precautions".

TESTING CONDITION: Before starting component function check, preparation of draining fuel and refilling fuel is required.

Do you have CONSULT?

YES >> GO TO 2.

NO >> GO TO 3.

2.PERFORM COMPONENT FUNCTION CHECK

With CONSULT

NOTE: Start from step 10, if it is possible to confirm that the fuel cannot be drained by 30 (77/8 US gal, 65/ 8 Imp gal) in advance.

  1. Prepare a fuel container and a spare hose.
  2. Release fuel pressure from fuel line, refer to EC133, "Work Procedure".
  3. Remove the fuel feed hose on the fuel level sensor unit.
  4. Connect a spare fuel hose where the fuel feed hose was removed.
  5. Turn ignition switch OFF and wait at least 10 seconds then turn ON.
  6. Select "FUEL LEVEL SE" in "DATA MONITOR" mode of "ENGINE" using CONSULT.
  7. Check "FUEL LEVEL SE" output voltage and note it.
  8. Select "FUEL PUMP RELAY" in "ACTIVE TEST" mode of "ENGINE" using CONSULT.
  9. Touch "ON" and drain fuel approximately 30 (77/8 US gal, 65/8 Imp gal) and stop it.
  10. Check "FUEL LEVEL SE" output voltage and note it.
  11. Fill fuel into the fuel tank for 30 (77/8 US gal, 65/8 Imp gal).
  12. Check "FUEL LEVEL SE" output voltage and note it.
  13. Confirm whether the voltage changes more than 0.03 V during step 7 to 10 and 10 to 12.

Is the inspection result normal?

YES >> INSPECTION END

NO >> Proceed to EC, "Diagnosis Procedure".

3.PERFORM COMPONENT FUNCTION CHECK

Without CONSULT

NOTE: Start from step 8, if it is possible to confirm that the fuel cannot be drained by 30 (77/8 US gal, 65/8 Imp gal) in advance.

  1. Prepare a fuel container and a spare hose.
  2. Release fuel pressure from fuel line. Refer to EC133, "Work Procedure".
  3. Remove the fuel feed hose on the fuel level sensor unit.
  4. Connect a spare fuel hose where the fuel feed hose was removed.
  5. Turn ignition switch ON.
  6. Drain fuel by 30 (77/8 US gal, 65/8 Imp gal) from the fuel tank using proper equipment.
  7. Confirm that the fuel gauge indication varies.
  8. Fill fuel into the fuel tank for 30 (77/8 US gal, 65/8 Imp gal).
  9. Confirm that the fuel gauge indication varies.

Is the inspection result normal?

YES >> INSPECTION END

NO >> Proceed to EC, "Diagnosis Procedure".

Diagnosis Procedure

1.CHECK COMBINATION METER FUNCTION

Refer to MWI, "CONSULT Function" (TYPE A) or MWI, "CONSULT Function" (TYPE B).

Is the inspection result normal?

YES >> Check intermittent incident. Refer to GI, "Intermittent Incident".

NO >> Refer to MWI, "Component Function Check" (TYPE A) or MWI, "Component Function Check" (TYPE B). Check the vehicle type to confirm the service information in MWI section. Refer to MWI, "Information".
