Event Code
Description Conditions which Activate the Code System Response
E360(3) Low Engine Oil Pressure The engine oil pressure has fallen below the trip point for the programmed delay time. The code is logged.
The shutdown output is activated.
The engine is shut down. Probable Causes
Low engine oil level
Incorrect oil viscosity
Contaminated engine oil
Faulty oil pressure sensors
Improper circulation of the engine oil
Worn componentsRecommended Actions
Low Engine Oil Level
Check the oil level. Add oil to the engine, if necessary.Incorrect Oil Viscosity
Confirm that the oil in the engine has the correct viscosity. For information that is related to the correct viscosity of engine oil for your engine application, refer to Operation and Maintenance Manual, "Refill Capacities and Recommendations".Contaminated Engine Oil
Engine oil that is contaminated with another liquid will cause low engine oil pressure. A high engine oil level can be an indication of contamination. Obtain an analysis of the engine oil. Determine the reason for contamination of the engine oil and perform the necessary repairs. Change the engine oil and the engine oil filter. For information that is related to the correct engine oil for your application, refer to Operation and Maintenance Manual, "Refill Capacities and Recommendations".Faulty Engine Oil Pressure Sensors
Use Cat ET to compare the status of the "Engine Oil Pressure" parameter to the "Unfiltered Engine Oil Pressure" parameter while the engine is off. Both readings should be close to zero pressure.If a reading is significantly different from zero, replace the suspect engine oil pressure sensor.Improper Circulation of the Engine Oil
Several factors could cause improper circulation of the engine oil:The engine oil filter may be clogged. Use Cat ET to check the status of the "Oil Filter Differential Pressure" parameter. A high differential pressure indicates that there may be a filter that is clogged. Replace the engine oil filter, if necessary.An engine oil line or a passage for engine oil that is obstructed can cause an low engine oil pressure. Inspect the oil lines for damage and/or for kinking.The engine oil cooler may be clogged. Thoroughly clean the engine oil cooler.There may be a problem with a piston cooling jet. Breakage, a restriction, or incorrect installation of a piston cooling jet will cause seizure of the piston. Inspect the condition of the piston cooling jets for each cylinder. Perform the necessary repairs.If a cooling jet sequence valve is damaged, missing, or stuck open, this can cause the oil pressure to be low. Check the condition of the cooling jet sequence valves. Ensure that the valves are in good repair. Perform any necessary repairs.The inlet screen of the suction tube for the engine oil pump may be restricted. This restriction will cause cavitation and a loss of engine oil pressure. Check the inlet screen on the suction tube and remove any material that may be restricting the flow of engine oil.The suction tube for the oil pump could be drawing in air. Check the joints of the tube for a good seal or for a damaged O-ring seal. Check the tube for cracks. Perform the necessary repairs.Check for a mechanical problem with the engine oil pump. Check the gears of the engine oil pump for excessive wear. Engine oil pressure is reduced by gears that have too much wear. Repair the pump, if necessary.The engine oil pump's pressure regulating valve or a bypass valve could be stuck in the open position. Clean the valve. Replace parts, if necessary.Worn Components
Excessive clearance at the crankshaft or camshaft bearings will cause low engine oil pressure. Also, inspect the clearance between the rocker arm shafts and the rocker arms. Check the engine components for excessive clearance.Obtain an analysis of the engine oil. Check the analysis for the level of wear metals in the engine oil.
