DTC CONFIRMATION PROCEDURE

1.PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.

  1.  Turn ignition switch OFF and wait at least 10 seconds.
  2.  Turn ignition switch ON.
  3.  Turn ignition switch OFF and wait at least 10 seconds.

>> GO TO 2.

2.PERFORM DTC CONFIRMATION PROCEDURE

  1.  Turn ignition switch ON and wait at least 5 seconds.
  2.  Check 1st trip DTC.

Is 1st trip DTC detected? YES >> Proceed to EC-274, "Diagnosis Procedure".

NO >> INSPECTION END

Diagnosis Procedure

1.CHECK DTC WITH COMBINATION METER

Refer to MWI-21, "CONSULT Function (METER/M&A)".

Is the inspection result normal? YES >> GO TO 2.

NO >> Proceed to MWI-62, "Component Function Check".

2.CHECK FUEL TANK TEMPERATURE (FTT) SENSOR POWER SUPPLY

  1.  Turn ignition switch OFF.
  2.  Disconnect fuel level sensor unit and fuel pump harness connector.
  3.  Turn ignition switch ON.
  4.  Check the voltage between fuel level sensor unit and fuel pump harness connector and ground.

Check fuel tank temperature (FTT) sensor power supply

Is the inspection result normal? YES >> GO TO 4.

NO >> GO TO 3.

3.CHECK FUEL TANK TEMPERATURE (FTT) SENSOR POWER SUPPLY CIRCUIT

  1.  Turn ignition switch OFF.
  2.  Disconnect ECM harness connector.
  3.  Check the continuity between fuel level sensor unit and fuel pump harness connector and ECM harness connector.

Check fuel tank temperature (FTT) sensor power supply circuit

  1. Also check harness for short to ground and to power.

Is the inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.

NO >> Repair or replace error-detected parts.

4.CHECK FUEL TANK TEMPERATURE (FTT) SENSOR GROUND CIRCUIT

  1.  Turn ignition switch OFF.
  2.  Disconnect ECM connector.
  3.  Check the continuity between fuel level sensor unit and fuel pump harness connector and ECM harness connector.

Check fuel tank temperature (FTT) sensor ground circuit

  1. Also check harness for short to power.

Is the inspection result normal? YES >> GO TO 5.

NO >> Repair or replace error-detected parts.

5.CHECK FUEL TANK TEMPERATURE (FTT) SENSOR

Check the FTT sensor. Refer to EC-276, "Component Inspection".

Is the inspection result normal? YES >> GO TO 6.

NO >> Replace “fuel level sensor unit and fuel pump”. Refer to FL-6, "Removal and Installation".

6.CHECK INTERMITTENT INCIDENT

Refer to GI-41, "Intermittent Incident".

>> INSPECTION END

Component Inspection

1.CHECK FUEL TANK TEMPERATURE (FTT) SENSOR

  1.  Turn ignition switch OFF.
  2.  Disconnect fuel level sensor unit and fuel pump harness connector.
  3.  Remove fuel level sensor unit. Refer to FL-6, "Removal and Installation".
  4.  Check resistance between fuel level sensor unit and fuel pump terminals by heating with hot water as shown in the figure.

Check fuel tank temperature (FTT) sensor

Check fuel tank temperature (FTT) sensor

Is the inspection result normal? YES >> INSPECTION END

NO >> Replace fuel level sensor unit and fuel pump. Refer to FL-6, "Removal and Installation".
