DTC DETECTION LOGIC
NOTE: If DTC P0196 is displayed with DTC P0197 or P0198, first perform the trouble diagnosis for DTC P0197 or P0198. Refer to EC, "DTC Logic".
DTC No. | Trouble diagnosis name | DTC detecting condition | Possible cause | |
P0196 | EOT SENSOR [Engine oil temperature (EOT) sensor circuit 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. |
|
B | The comparison result of signals transmitted 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 higher/ lower than that of other temperature sensors when the engine is started with its cold state. |

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 procedure before conducting the next test.
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 AI
Is 1st trip DTC detected?
YES >> Proceed to EC, "Diagnosis Procedure".
NO >> GO TO 4.
4.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION AII
With CONSULT
Then perform the following steps.
NOTE: Do not turn ignition switch OFF until step 8.
If they are out of the specified range, soak the vehicle to meet the above conditions. Then perform the following steps.
NOTE: - Do not turn ignition switch OFF.
- If it is supposed to need a long period of time, do not deplete the
battery.
With GST
Follow the procedure "With CONSULT" above.
Is 1st trip DTC detected?
YES >> Proceed to EC, "Diagnosis Procedure".
NO >> GO TO 5.
5.PERFORM COMPONENT FUNCTION CHECK (FOR MALFUNCTION B)
Perform component function check. Refer to EC, "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, "Diagnosis Procedure".
6.PRECONDITIONING
If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following procedure before conducting the next test.
TESTING CONDITION:
>> GO TO 7.
7.PERFORM DTC CONFIRMATION PROCEDURE B
NOTE: Cool the vehicle in an environment of ambient air temperature between −10C (14F) and 35C (95F).
CAUTION: Never turn ignition switch ON during soaking. NOTE: The vehicle must be cooled with the food open.
CAUTION: Never turn ignition switch OFF during idling.
Is 1st trip DTC detected?
YES >> Proceed to EC, "Diagnosis Procedure".
NO >> INSPECTION END
1.CHECK ENGINE OIL TEMPERATURE (EOT) SENSOR
Is the inspection result normal?
YES >> Check intermittent incident. Refer to GI, "Intermittent Incident".
NO >> Proceed to EC, "Diagnosis Procedure".
Diagnosis Procedure
1.CHECK ENGINE OIL TEMPERATURE (EOT) SENSOR
Check EOT sensor. Refer to EC, "Component Inspection".
Is the inspection result normal?
YES >> Check intermittent incident. Refer to GI, "Intermittent Incident".
NO >> Replace EOT sensor. Refer to EM, "Exploded View".
Component Inspection
1.CHECK ENGINE OIL TEMPERATURE SENSOR
Is the inspection result normal?
YES >> INSPECTION END
NO >> Replace engine oil temperature sensor. Refer to EM, "Exploded View".

VALVE OIL SEAL : Removal and Installation
REMOVAL
Remove camshafts.
Remove valve lifters.
Rotate crankshaft, and set piston with valve oil seal to be removed to
TDC. This will prevent the valve
from dropping into cylinder.
CAUTION:
When rotating crankshaft, be careful to avoid ...

Diagnosis Procedure
1.CHECK START
Check front and rear brake force distribution using a brake tester.
Is the inspection result normal?
YES >> GO TO 2
NO >> Check brake system.
2.CHECK FRONT AND REAR AXLE
Make sure that there is no excessive play in the front and rear axles. Refer ...
