Event Code    
Code and Description    Conditions which Generate this Code    System Response    
E360(1) Low Engine Oil Pressure     The engine oil pressure is below the trip point and the delay time has expired.     The code is logged.    
E360(3) Low Engine Oil Pressure     The code is logged.
Engine power is derated.
If the vehicle's ground speed is zero and the parking brake is set, the engine will be shut down. Probable Causes
Low engine oil level
Incorrect viscosity
Contaminated engine oil
Faulty oil pressure sensors
Poor circulation of the engine oil
Worn componentsRecommended Actions
Low Engine Oil Level
Check the oil level. Add oil, as needed.Incorrect Viscosity
Make sure that the engine is supplied with the correct engine oil. For the correct engine oil to use, refer to the Operation and Maintenance Manual.Contaminated Engine Oil
Engine oil that is contaminated with another liquid will cause low engine oil pressure. 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 make the necessary repairs. Change the engine oil and the engine oil filter. For the correct engine oil to use, refer to the Operation and Maintenance Manual.Faulty Engine Oil Pressure Sensors
Use the Cat ET to compare the readings of the "Unfiltered Oil Pressure (abs)" and the "Engine Oil Pressure (abs)" while the engine is off. Check that the sensors are correctly wired.If a reading is significantly different from the atmospheric pressure, troubleshoot the sensor circuit(s). Refer to Troubleshooting, "Sensor Signal (Analog, Active) - Test".Poor Circulation of the Engine Oil
Several factors could cause poor circulation of the engine oil:The engine oil filter may be clogged. Replace the engine oil filter.An engine oil line or a passage for engine oil may be disconnected or broken.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.The inlet screen of the suction tube for the engine oil pump can have a restriction. 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 engine oil flow.The suction tube may be drawing in air. Check the joints of the tube for cracks or for a damaged O-ring seal.There may be a 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.The engine oil pump's pressure regulating valve or a bypass valve is 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
