Schematic for engine 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 on your engine.
Table 1
Sensor     MUI Engines     EUI Engines     PEEC Engines    
Coolant Temperature     Yes     No     Yes    
Oil Pressure     Yes     No     Yes    
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 handles a diagnostic code that is associated with the sensor power supply 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
