Schematic for the oil temperature sensorThe EMCP II+P has a sensor supply voltage of 8 DCV from the GSC+P that powers the engine sensors. The sensors may vary according to the engine. Refer to table 1 in order to determine the sensors that are on your engine.

Coolant Loss     Yes     Yes     Yes    
Oil Temperature     No     Yes     Yes    The engine oil temperature sensor is optional. The engine coolant fluid level sensor is optional.The sensor power supply functions whenever power is applied to the GSC+P.The GSC+P is usually programmed in the factory. The GSC+P deals with a problem with the sensor power supply CID 0269 FMI 03 as an alarm fault. P004 = 0. If the GSC+P is programmed to shutdown, P004 is equal to 1 for a problem with the sensor power supply. It is not necessary to press the "Alarm Codes" key in order to view the CID 0269 FMI 03. The CID 0269 FMI 03 is automatically shown on the upper display.Diagnostic codes are created when the harness connector is disconnected from the GSC+P during these troubleshooting procedures. Clear these created diagnostic codes after the particular problem is corrected and the particular diagnostic code is cleared. The possible cause of a CID 0269 FMI 03 happens when the voltage of the sensor power supply is greater than 8.5 DCV.Begin performing these procedures only when CID 0269 FMI 03 is showing and the "DIAG" indicator is FLASHING on the upper display. The GSC+P treats a CID 0269 FMI 03 as an alarm fault. Active alarm faults are shown on the upper display when the "Alarm Codes" key is pressed and the Engine Control Switch (ECS) is in any position except the OFF/RESET position. For an inactive diagnostic code, the problem may be intermittent. To troubleshoot an inactive diagnostic code, use the preceding system schematic and Refer to
