2. Check 1st trip DTC.
Is 1st trip DTC detected?
YES >> Proceed to EC-241, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000009462192
1.CHECK INTAKE AIR TEMPERATURE SENSOR POWER SUPPLY
1. Turn ignition switch OFF.
2. Disconnect mass air flow sensor (with inta ke air temperature sensor) harness connector.
3. Turn ignition switch ON.
4. Check the voltage between mass air flow sensor harness connector and ground.
Is the inspection result normal?
YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK INTAKE AIR TEMPERATURE SENSOR POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between mass air flow sensor harness connector and ECM harness connector.

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-244, "Component Function Check"
.
NOTE:
Use the component function check to check the overall func tion 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-244, "Diagnosis Procedure"
.
3.PRECONDITIONING
If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following proce-
dure before conducti ng 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.
TESTING CONDITION:
• Before performing the following procedure, do not add fuel.
• Before performing the following procedure, check that fuel level is between 1/4 and 4/4.
• Before performing the following procedure, confirm that battery voltage is 11 V or more at idle.
>> GO TO 4.
4.PERFORM DTC CONFIRMATION PROCEDURE
1. Move the vehicle to a cool place. NOTE:
Cool the vehicle in an environment of ambient air temperature between −10 °C (14 °F) and 35 °C (95 °F).
2. Turn ignition switch OFF and leave the vehicle for 12 hours. CAUTION:
Never turn ignition switch ON during this procedure.
NOTE:
The vehicle must be cooled with the food open.
3. Start engine and let it idle for 5 minutes or more. CAUTION:
Never turn ignition swit ch OFF during idling.
4. Check 1st trip DTC.
DTC No. CONSULT screen terms
(Trouble diagnosis content) DTC detecting condition Possible cause
P0116 ECT SEN/CIRC
(Engine coolant temperature
sensor 1 circuit range/perfor-
mance) 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. • Harness or connectors
(High or low resistance in the ECT
sensor circuit)
• ECT sensor
