Component Inspection

■ "Oil temperature sensor" Inspection 

1. Ignition "OFF".
2. Disconnect Oil temperature sensor connector.
3. Measure the resistance across the two terminals of the Oil Temperature sensor.

   Specification:  Approx. 12V

4. Is the measured resistance within specifications?

   YES 

   • Go to "PCM/TCM Inspection" procedure below.

   NO 

   • Replace Oil temperature sensor as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

■ PCM/TCM  

1. Ignition "ON" & Engine "OFF".
2. Connect Oil temperature sensor connector.
3. Connect scantool 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.

   ⓧ It is subject to change vehicle condition.

5. Is measured Oil temperature sensor value changed by simulating voltage?

   YES 

   • Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair as necessary and go to "VERIFICATION VEHICLE REPAIR " procedure.

   NO 

   • Substitute with a known-good PCM/TCM and check for proper operation. If the problem is corrected, replace PCM/TCM and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
