(20) Pressure switch for the prelubrication Engine coolant pressure sensor for the outlet (8) - A pressure switch is located at the outlet for the engine jacket water. If the outlet pressure is too low, the control system will activate a shutdown.Engine oil temperature sensor (9) - An oil temperature sensor measures the engine oil temperature. A high oil temperature will activate an alarm or a shutdown. The trip points can be programmed with Cat ET. To observe the output value of the sensor, use Cat ET to view the "Engine Oil Temperature" parameter.Engine coolant temperature sensor (10) - The temperature sensor is located in the water temperature regulator housing. To monitor the coolant temperature, the element must be in contact with the coolant. Otherwise, the sensor will not function properly. A high coolant temperature will activate an alarm or a shutdown. A low coolant temperature will only activate an alarm. The trip points for the activation can be programmed with Cat ET. The engine can be restarted after a shutdown due to high engine coolant temperature. However, another shutdown will occur after one minute if the temperature remains high. To observe the value of the output of the sensor, use Cat ET to view the "Engine Coolant Temperature" parameter.Intake manifold air temperature sensor (11) - A sensor for monitoring the manifold air temperature is located in the inlet elbow for the number one cylinder head. Excessive manifold air temperature can activate an alarm or a shutdown during high load or low load operation. The trip points for activation can be programmed with Cat ET. To observe the value of the output of the sensor, use Cat ET to view the "Inlet Air Temperature" parameter.Oil pressure sensors (12) and (13) - The engine oil pressure is measured before the oil filters (12) and after the oil filters (13). An alarm or a shutdown can be activated by any of the following occurrences: low filtered oil pressure, low oil filter differential pressure and high oil filter differential pressure. The trip point for the activation of a warning or a shutdown for oil filter differential pressure can be programmed with Cat ET. To observe the value of the output of the sensor, use Cat ET to view the "Engine Oil Pressure" or the "Unfiltered Engine Oil Pressure" parameter.NOX sensor (14) and NOX buffer (14) - The NOX sensor and the NOX buffer generate a signal that is proportional to the percent of NOX in the exhaust manifold. The control system uses the signal to adjust the air/fuel ratio in order to achieve the level of emissions that is desired. To observe the output value of the sensor, use Cat ET to view the "Actual NOx" parameter.Coolant pressure switch for the inlet (15) - A pressure switch is located at the inlet for the engine jacket water. If the inlet pressure is too high, the switch will activate a shutdown. To observe the status of the switch, use the Caterpillar Electronic Technician (ET) to view the "Engine Coolant Pump Pressure" parameter.Speed/timing sensor (16) - The engine speed/timing sensor is located on the rear end of the left camshaft. The engine speed/timing sensor is monitored in order to determine the position of the crankshaft and the engine rpm. The control sy
