DTC CONFIRMATION PROCEDURE
1.
INSPECTION START
Is it necessary to erase permanent DTC?
YES
>> GO TO 6.
NO
>> GO TO 2.
2.
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, confirm that battery voltage is 11 V or more at idle.
>> GO TO 3.
3.
PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION A-I
1. Start engine and warm it up to normal operating temperature.
2. Turn ignition switch OFF and wait at least 10 seconds.
3. Turn ignition switch ON.
4. Turn ignition switch OFF and wait at least 10 seconds.
5. Start engine and let it idle for 5 minutes and 10 seconds.
6. Check 1st trip DTC.
Is 1st trip DTC detected?
YES
>> Proceed to
.
NO
>> GO TO 4.
4.
PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION A-II
With CONSULT
1. Select “DATA MONITOR” mode of “ENGINE” using CONSULT.
2. Check that “COOLAN TEMP/S” indicates above 80
°C (176°F).
If it is above 80
°C (176°F), go to the following steps.
DTC No.

EOT SENSOR
[Engine oil temperature (EOT)
sensor circuit range/perfor-
mance]
A)
Rationally incorrect voltage from the
sensor is sent to ECM, compared with
the voltage signals from EOT sensor
and intake air temperature sensor 1.
• Harness or connectors
(EOT sensor circuit is open or short-
ed)
• EOT sensor
B)
The comparison result of signals trans-
mitted to ECM from each temperature
sensor (IAT sensor1, IAT sensor 2, ECT
sensor, FTT sensor, and EOT sensor)
shows that the signal voltage of the EOT
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 EOT
sensor circuit)
• EOT sensor
