id0102s4211900

DTC P0196:00

Engine oil temperature sensor circuit range/performance problem
DETECTION CONDITION
•  When the following conditions are met, the engine oil temperature is 20 °C {68 °F} or more for a continuous 1 s:
MONITORING CONDITIONS
―  6 h or more has passed since the ignition was switched off.
―  Battery voltage: 8 V or more
Diagnostic support note
•  This is a continuous monitor (CCM).
•  The check engine light illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
•  PENDING CODE is available if the PCM detects the above malfunction condition during first drive cycle.
•  FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
•  The DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION
•  The fast idle up correction for the idle speed control is inhibited.
•  Inhibits engine-stop by operating the i-stop function.
POSSIBLE CAUSE
•  ECT sensor connector or terminals malfunction
•  Engine oil temperature sensor/engine oil pressure sensor connector or terminals malfunction
•  PCM connector or terminals malfunction
•  Engine oil temperature sensor malfunction
•  ECT sensor malfunction
•  PCM malfunction

Diagnostic Procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED
•  Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA (Mode 2)/snapshot data on the repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
INSPECT ECT SENSOR CONNECTOR CONDITION
•  Switch the ignition to off.
•  Disconnect the ECT sensor connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to Step 8.
No
Go to the next step.
4
INSPECT ENGINE OIL TEMPERATURE SENSOR/ENGINE OIL PRESSURE SENSOR CONNECTOR CONDITION
•  Disconnect the engine oil temperature sensor/engine oil pressure sensor connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to Step 8.
No
Go to the next step.
5
INSPECT PCM CONNECTOR CONDITION
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to Step 8.
No
Go to the next step.
6
INSPECT ENGINE OIL TEMPERATURE SENSOR
•  Inspect the engine oil temperature sensor.
•  Is there any malfunction?
Yes
Replace the engine oil temperature sensor/engine oil pressure sensor, then go to Step 8.
(See ENGINE OIL TEMPERATURE SENSOR/ENGINE OIL PRESSURE SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
No
Go to the next step.
7
INSPECT ECT SENSOR
•  Inspect the ECT sensor.
•  Is there any malfunction?
Yes
Replace the ECT sensor, then go to the next step.
(See ENGINE COOLANT TEMPERATURE (ECT) SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
No
Go to the next step.
8
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Leave the vehicle for 6 hours or more.
•  Start the engine and idle it for 1 min.
•  Perform the DTC Reading Procedure.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM.
Go to the next step.
No
Go to the next step.
9
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [SKYACTIV-D 2.2].)
No
DTC troubleshooting completed.
