NO
>> Repair or replace error-detected parts.
3.
CHECK INTAKE AIR TEMPERATURE SENSOR GROUND 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.
4. Also check harness for short to power.
Is the inspection result normal?
YES
>> GO TO 4.
NO
>> Repair or replace error-detected parts.
4.
CHECK INTAKE AIR TEMPERATURE SENSOR
Check the intake air temperature sensor. Refer to
EC-210, "Component Inspection"
Is the inspection result normal?
YES
>> GO TO 5.
NO
>> Replace mass air flow sensor (with intake air temperature sensor). Refer to
5.

DTC CONFIRMATION PROCEDURE
1.
INSPECTION START
Is it necessary to erase permanent DTC?
YES
>> GO TO 3.
NO
>> GO TO 2.
2.
CHECK ENGINE COOLANT TEMPERATURE (ECT) SENSOR
1. Turn ignition switch OFF.
2. Disconnect ECT sensor harness connector.
3. Remove ECT sensor. Refer to
.
4. Check resistance between ECT sensor terminals by heating
with hot water as shown in the figure.
Is the inspection result normal?
YES
>> GO TO 5.
NO
>> Proceed to
.
3.
PRECONDITIONING
If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following proce-
dure before conducting 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.
DTC No.

ECT SENSOR
(Engine coolant temperature sensor 1 cir-
cuit range/performance)
The comparison result of signals transmitted to ECM from each tempera-
ture 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.

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 hood open.
3. Start engine and let it idle for 5 minutes or more.
CAUTION:
Never turn ignition switch OFF during idling.
4. Check 1st trip DTC.
