DTC No. | CONSULT screen terms (Trouble diagnosis content) | DTC detecting condition | Possible cause |
P0116 | ECT SEN/CIRC (Engine coolant temperature sensor 1 circuit range/performance) | The comparison result of signals transmitted to ECM from each temperature sensor (IAT sensor, ECT sensor, FTT sensor, and EOT sensor) shows that the voltage signal of the ECT sensor is higher/lower than that of other temperature sensors when the engine is started with its cold state. |

DTC CONFIRMATION PROCEDURE
1.INSPECTION START
Is it necessary to erase permanent DTC? YES >> GO TO 3.
NO >> GO TO 2.
2.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-197, "Component Function Check".
NOTE:
Use the component function check to check the overall function of the ECT sensor circuit. During this check, a 1st trip DTC might not be confirmed.
Is the inspection result normal? YES >> INSPECTION END
NO >> Proceed to EC-197, "Diagnosis Procedure".
3.PRECONDITIONING
If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following procedure before conducting the next test.
TESTING CONDITION:
>> GO TO 4.
4.PERFORM DTC CONFIRMATION PROCEDURE
NOTE:
Cool the vehicle in an environment of ambient air temperature between −10В°C (14В°F) and 35В°C (95В°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-197, "Diagnosis Procedure".
NO >> INSPECTION END
Component Function Check
1.CHECK ENGINE COOLANT TEMPERATURE (ECT) SENSOR
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Proceed to EC-197, "Diagnosis Procedure".
Diagnosis Procedure
1.CHECK ENGINE COOLANT TEMPERATURE (ECT) SENSOR
Check ECT sensor. Refer to EC-197, "Component Inspection".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace ECT sensor. Refer to CO-24, "Exploded View".
Component Inspection
1.CHECK ENGINE COOLANT TEMPERATURE (ECT) SENSOR
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace engine coolant temperature sensor. Refer to CO-24, "Exploded View"
