NO >> GO TO 3.
3.CHECK FUEL TANK TEMPERATURE (FTT) SENSOR POWER SUPPLY CIRCUIT
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
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-259, "Component Inspection".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace “fuel level sensor unit and fuel pump”. Refer to FL-6, "Removal and Installation".
Component Inspection
1.CHECK FUEL TANK TEMPERATURE (FTT) SENSOR
