P0196

P0196

Component Location:

General Description
The fluid of the CVVT is the engine oil and its density changes according to the engine oil temperature. At this time the Oil Temperature Sensor (OTS) helps compensation against the temperature differences. The Oil Temperature Sensor measures the engine oil temperature before the engine oil comes into the Oil-flow Control Valve (OCV).
According to the measured temperature, the Engine Control Module (ECM) compensates the oil-flow control valve operation time.

DTC Description
Checking the oil temperature, coolant temperature and intake air temperature every 25 sec. under detecting condition, if the difference in temperature at start-up exceeds threshold value, PCM sets P0196. MIL(Malfunction Indication Lamp) turns on when the malfunction lasts till consecutive 2 driving cycle.

DTC Detecting Condition:

Specification:

Schematic Diagram:

Monitor DTC Status
1. Check DTC Status
1. Connect scantool to Data Link Connector(DLC).
2. IG "ON".
3. Select "Diagnostic Trouble Codes(DTCs)" mode, and then Press F5(INFO) to check DTC's information from the DTCs menu
4. Read "DTC Status" parameter.






5. Is parameter displayed "Present fault"?

YES
a. Go to "Component Inspection" procedure.

NO
a. Fault is intermittent caused by PCM memory was not cleared after repair.
Erase DTC and drive the vehicle to satisfy the enable condition then, go to "Component Inspection" procedure.

Component Inspection
1. Check resistance of OTS
1. IG "ON" & ENG "OFF"
2. Monitor Oil Temperature parameter on the scantool
3. IG "OFF" & ENG "OFF"
4. Disconnect OTS connector.
5. Measure resistance between terminal 1 and 2 of OTS connector(Component Side) after checking out the oil temperature with scantool

Specification :






6. Is the measured resistance within specification ?

YES - Go to "Verification of Vehicle Repair" procedure.

NO - Substitute with a known - good OTS and check for proper operation. If the problem is corrected, replace OTS and go to "Verification of Vehicle Repair" procedure.

Verification of Vehicle Repair
After a repair, it is essential to verify that the fault has been corrected.
1. Connect scan tool and select "Diagnostic Trouble Codes(DTCs)" mode
2. Press F5(INFO) and confirm that "DTC Readiness Flag" indicates "Complete". If not, drive the vehicle within conditions noted in the freeze frame data or enable conditions
3. Read "DTC Status" parameter
4. Is parameter displayed "History(Not Present) fault"?

YES - System performing to specification at this time. Clear the DTC

NO - Go to the applicable troubleshooting procedure.
