NOTE:

If DTC P0196 is displayed with DTC P0197 or P0198, first perform the trouble diagnosis for DTC P0197 or

P0198. Refer to

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-1

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

EC-722, "Diagnosis Procedure"

.

NO

>> GO TO 4.

4.

PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION A-2

With CONSULT

1. Select “DATA MONITOR” mode of “ENGINE” using CONSULT.

2. Check that “COOLAN TEMP/S” indicates above 60

°C (140°F).

If it is above 60

°C (140°F), go to the following steps.

DTC No.

CONSULT screen terms

(Trouble diagnosis content)

DTC detecting condition

Possible cause

P0196

EOT SENSOR
(Engine oil temperature sensor
range/performance)

A)

Rationally incorrect voltage from the
sensor is sent to ECM, compared with
the voltage signals from EOT sensor
and intake air temperature sensor.

• 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 sensor, ECT sensor, FTT
sensor, and EOT sensor) shows that the
signal voltage of the EOT sensor is high-
er/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

If it is below 60

°C (140°F), warm engine up until “COOLAN TEMP/S” indicates more than 60°C (140°F).

Then perform the following steps.

3. Turn ignition switch OFF and soak the vehicle in a cool place.

4. Turn ignition switch ON.

NOTE:

Do not turn ignition switch OFF until step 8.

5. Select “DATA MONITOR” mode of “ENGINE” using CONSULT.

6. Check the following.

If they are within the specified range, perform the following steps.

If they are out of the specified range, soak the vehicle to meet the above conditions. Then perform the fol-

lowing steps.

NOTE:

• Do not turn ignition switch OFF.

• If it is supposed to need a long period of time, do not deplete the battery.

7. Start engine and let it idle for 5 minutes.

8. Check 1st trip DTC.

With GST

Follow the procedure “With CONSULT” above.
Is 1st trip DTC detected?

YES

>> Proceed to

EC-722, "Diagnosis Procedure"

.

NO

>> GO TO 5.

5.

PERFORM COMPONENT FUNCTION CHECK (FOR MALFUNCTION B)

Perform component function check. Refer to

EC-722, "Component Function Check"

.

NOTE:

Use the component function check to check the overall function of the EOT 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-722, "Diagnosis Procedure"

.

6.

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 7.

7.

PERFORM DTC CONFIRMATION PROCEDURE B

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.
