April 5, 2026: LEMON Manuals is launched! Read the announcement.

Component Inspection

Check resistance of OTS

IG "ON" & ENG "OFF"
Monitor Oil Temperature parameter on the scan tool
IG "OFF" & ENG "OFF"
Disconnect OTS connector.

Measure resistance between terminal 1 and 2 of OTS connector(Component Side)

SPECIFICATION :

RESISTANCE SPECIFICATION

Temperature(°C/°F)	Resistance(kΩ)
-20°C/ -4°F	16.52kΩ
20°C/ 68°F	2.45kΩ
80°C/ 176°F	0.29kΩ

Is the measured resistance within specification ?
YES
- Go to 2"Check PCM" as follows.
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.

Check PCM
1. Ignition "OFF" and Connect Scan Tool
2. Ignition "ON" & Engine "OFF"
3. Select simulation function on scan tool.
4. Simulate voltage at terminal "1" of OTS signal harness connector.

5. Does the OTS signal value changes according to simulation voltage ?
  YES
  - Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace if 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 go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NOTE: There is a memory reset function on scan tool that can erase optional parts automatically detected and memorized by PCM. After testing PCM on the vehicle, use this function before reusing the PCM
