Is the measured resistance within specifications?
 | ▶ Go to "PCM/TCM Inspection" procedure. |
 | ▶ Replace Oil temperature sensor as necessary and then go to "Verification of Vehicle Repair" procedure. |
Ignition off.
Disconnected Oil temperature sensor connector.
Measure the resistance across the two terminals of the Oil Temperature sensor.
Specification : See blow Oil temperature sensor specification table

-20℃ | Approx. 47.4 | 100℃ | Approx. 0.63 | |
0℃ | Approx. 18.6 | 120℃ | Approx. 0.38 | |
20℃ | Approx. 8.1 | 140℃ | Approx. 0.25 | |
40℃ | Approx. 3.1 | 160℃ | Approx. 0.16 | |
60℃ | Approx. 1.98 |
Is the measured resistance within specifications?
| ▶ Go to "PCM/TCM Inspection" procedure. |
| ▶ Replace Oil temperature sensor as necessary and then go to "Verification of Vehicle Repair" procedure. |
Ignition off & Engine Off.
Connect Oil temperature sensor connector.
Connect GDS to Data Link Connector(DLC) and select Simulation mode.
Input 0 -> 5 vlotage at Oil temperature sensor signal line by simulation mode and Monitoring Oil temperature sensor.
Fig 1) Simulation Output 3.00V → 39℃
Fig 2) Simulation Output 4.00V → 20℃
※ It is subject to change vehicle condition.
Is measured Oil temperature sensor value changed by input voltage?
| ▶ Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair as necessary and go to "Verification Vehicle Repair" procedure. |
| ▶ 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. |
