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-248, "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
.
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.
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 switch ON during soaking.
NOTE:
The vehicle must be cooled with the hood open.

ECT SEN/CIRC
[Engine coolant temperature
(ECT) sensor circuit range/per-
formance]
The comparison result of signals transmitted
to ECM from each temperature sensor (IAT
sensor 1, IAT sensor 2, ECT sensor, FTT
sensor, and EOT sensor) shows that the volt-
age 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
