Is the measured resistance within specifications?
YES
- Go to " 2 PCM Inspection" procedure.
NO
- Replace Oil temperature sensor as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

PCM Inspection
1. Ignition off & Engine Off.
2. Connect Oil temperature sensor connector.
3. Connect GDS to Data Link Connector(DLC) and select Simulation mode.
4. Input 0 -> 5 voltage at Oil temperature sensor signal line by simulation mode and Monitoring Oil temperature sensor.

  - It is subject to change vehicle condition.
5. Is measured Oil temperature sensor value changed by input voltage?
  YES
  - Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
  NO
  - Substitute with a known-good PCM and check for proper operation. If the problem is corrected, replace PCM and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
