KIT-SEAL 1247009 - Caterpillar

The ECM automatically performs the following functions for low engine oil pressure:
Warning
ShutdownThe strategy is based on a map of the engine oil pressure versus the engine rpm. The default settings that are programmed at the factory are listed in Table 1.

Map of the engine oil pressure versus the engine rpm (Y) Engine oil pressure in kPa (X) Engine rpm (1) Hysteresis (minimum and maximum oil pressure) (2) Normal engine oil pressureIf the engine oil pressure is below the minimum pressure for four seconds, a warning will occur. To deactivate the warning, the engine oil pressure must rise above the hysteresis that is set in the map.If the engine oil pressure is below the minimum pressure for nine seconds, a shutdown will occur.The map cannot be reprogrammed.
