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-196, "
Component Function Check".
NOTE:
Use the component function check to check the overall func tion of the IAT 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-196, "
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. Start engine and let it idle for 60 minutes.
2. 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).
3. Turn ignition switch OFF and soak the vehicle for 12 hours. CAUTION:
Never turn ignition sw itch ON during soaking.
NOTE:
The vehicle must be cooled with the hood open.
4. Start engine and let it idle for 5 minutes or more. CAUTION:
Never turn ignition swit ch OFF during idling.
5. Check 1st trip DTC.

[Intake air temperature (IAT) sen-
sor circuit range/performance] The comparison result of signals transmitted to ECM
from each temperature sensor (IAT sensor, ECT sensor,
FTT sensor, and EOT sensor) sh
ows that the voltage sig-

temperature sensors when the engine is started with its
cold state. • Harness or connectors
