Check OTS resistance
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 signal and ground terminals of OTS connector after checking out the oil temperature with scantool
A. Specification :









6. Is the measured resistance within specification ?

1) 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.
