Diagnostic Aids
- The following conditions may cause an intermittent: Intermittent short to ground in oil temperature circuit No. 357 (Dark Green/White wire) or an internal short to ground in oil temperature sensor. If circuit No. 357 (Dark Green/White wire) or oil temperature sensor is shorted to ground, IPC will display a constant oil temperature of 392°F (200°C).
- To verify if IPC can recognize a change in resistance from oil temperature sensor, disconnect oil temperature sensor. If IPC displays oil temperature as LOW, circuit No. 357 (Dark Green/White wire) and IPC are operating properly. Check oil temperature sensor.
