ADAPTER-FUEL NOZZLE 7W1902 - Caterpillar

The information from the sensors enables the Electronic Control Module (ECM) to control the engine as efficiently as possible over a wide range of operating conditions.The sensors also enable the module to activate alarms, impending shutdowns, and shutdowns in response to abnormal operation. The functions of the sensors are described below.Air Filter Differential Pressure
The air filter differential pressure sensor monitors the level of restriction across the air filter by comparing the sensors value to the value provided from the ambient pressure sensor. Restriction levels greater than 7 KPA will generate a warning event.Barometric Pressure Sensor
The sensor monitors the local atmospheric pressure in absolute.Crankcase Pressure Sensor
Note: The crankcase pressure sensor is only available for the G3512H engine application.When the engine crankcase pressure increases or decreases to the set trip points, the ECM will generate a warning or a shutdown. The trip point can be programmed with a customer password. The warning and shutdown are always active.Note: Low pressure only has a
