DTC Description
DTC DETECTION LOGIC
DTC No. | CONSULT screen terms (Trouble diagnosis content) | DTC detecting condition | |
P0181 | FTT SENSOR (Fuel temperature sensor ″A″ circuit range/ performance) | A | Rationally incorrect voltage from the sensor is sent to ECM, compared with the voltage signals from ECT sensor and intake air temperature sensor. |
B | The comparison result of signals transmitted to ECM from each temperature sensor (IAT sensor, ECT sensor, EOT sensor, and FTT sensor) shows that the voltage signal of the FTT sensor is higher/lower than that of other temperature sensors when the engine is started with its cold state. |
POSSIBLE CAUSE
DTC P0181 - A
DTC P0181 - B

NO >> GO TO 6.
6.CHECK FUEL TANK TEMPERATURE (FTT) SENSOR
Is the inspection result normal? YES >> GO TO 9.
NO >> Proceed to EC-272, "Diagnosis Procedure".
7.PRECONDITIONING
If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following procedure before conducting the next test.
TESTING CONDITION:
>> GO TO 8.
8.PERFORM DTC CONFIRMATION PROCEDURE B
NOTE: Cool the vehicle in an environment of ambient air temperature between −10°C (14°F) and 35°C (95°F).
CAUTION: Never turn ignition switch ON during this procedure.
NOTE: The vehicle must be cooled with the food open.
CAUTION:Never turn ignition switch off during idling.
Is 1st trip DTC detected? YES >> Proceed to EC-272, "Diagnosis Procedure".
NO >> INSPECTION END
9.CHECK INTERMITTENT INCIDENT
Refer to GI-41, "Intermittent Incident".
>> INSPECTION END
Diagnosis Procedure
1.INSPECTION START
Confirm the detected malfunction (A or B). Refer to EC-270, "DTC Description".
Which malfunction is detected? A >>GO TO 2.
B >>GO TO 6.
2.CHECK DTC WITH COMBINATION METER
Check DTC with combination meter. Refer to MWI-21, "CONSULT Function (METER/M&A)".
Is the inspection result normal? YES >> GO TO 3.
NO >> Proceed to MWI-62, "Component Function Check".
3.CHECK FUEL TANK TEMPERATURE (FTT) SENSOR POWER
Is the inspection result normal? YES >> GO TO 5.
NO >> GO TO 4.
4.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.
5.CHECK FTT SENSOR GROUND CIRCUIT
Is the inspection result normal? YES >> GO TO 6.
NO >> Repair or replace error-detected parts.
6.CHECK FUEL TANK TEMPERATURE (FTT) SENSOR
Check the FTT sensor. Refer to EC-273, "Component Inspection".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-41, "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
the inspection result normal? YES >> INSPECTION END
NO >> Replace fuel level sensor unit and fuel pump. Refer to FL-6, "Removal and Installation".
