BUSHING 1620150 - Caterpillar

System Operation Description:This procedure covers the following diagnostic codes:
1719-3 Generator Output Power Sensor : Voltage Above Normal
1719-9 Generator Output Power Sensor : Abnormal Update Rate
1719-12 Generator Output Power Sensor : FailureThe control system monitors the generator's output power in order to accurately control the air/fuel ratio. The control system uses a load signal from one of the following sources in order to monitor the generator's output power:
Electronic Modular Control Panel II+ (EMCP II+)
Programmable Logic Controller (PLC)
WattmeterThe PLC and the wattmeter are also called power sensors.The Engine is Not Equipped with an Auxiliary Sensing Module (ASM).If the generator is equipped with the EMCP II+, the master Electronic Control Module (ECM) receives the load signal from the Generator Set Control + (GSC+) via the Cat Data Link. If the generator is not equipped with the EMCP II+, the master Electronic Control Module (ECM) receives the load signal from a power sensor via terminal J1-25. The load signal from the power sensor is an analog voltage. The load signal increases from 0 VDC to 4.8 VDC as the generator's output increases to the maximum output.On powerup,
