P0183 | FTT SEN/CIRCUIT (Fuel temperature sensor ″A″ circuit high) | An excessively high voltage from the sensor is sent to ECM. |
DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
Is 1st trip DTC detected? YES >> Proceed to EC-258, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK DTC WITH COMBINATION METER
Refer to MWI-17, "CONSULT Function (METER/M&A)".
Is the inspection result normal? YES >> GO TO 2.
NO >> Proceed to MWI-58, "Diagnosis Procedure".
2.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
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".

DTC Logic
DTC DETECTION LOGIC
When a misfire occurs, engine speed will fluctuate. If the engine speed
fluctuates enough to cause the crankshaft
position (CKP) sensor (POS) signal to vary, ECM can determine that a misfire is
occurring.
