100-1
Low Engine Oil Pressure E360 (3)
Low Engine Oil Pressure Oil pressure is lower than the specified pressure for at least 4 seconds. Engine power is reduced. A snapshot is triggered. The code is logged. Factory passwords are required.
After 30 seconds, the ECM will shut down the engine if the "Engine Monitoring Mode" parameter is programmed to "Shut down".
100-17
Low Engine Oil Pressure E360 (1)
Low Engine Oil Pressure Oil pressure is below the specified pressure for at least 8 seconds. A snapshot is triggered. The code is logged. Engine performance is not affected.
100-18
Low Engine Oil Pressure E360 (2)
Low Engine Oil Pressure Oil pressure is lower than the specified pressure for at least 4 seconds. Engine power is reduced. A snapshot is triggered. The code is logged. Factory passwords are required.
After 30 seconds, the Engine Control Module (ECM) will shut down the engine if the "Engine Monitoring Mode" parameter is programmed to "Shut down". Probable Causes
Low engine oil level
Aeration in the oil
Low oil viscosity
Plugged Oil Filter
Faulty oil pump
Faulty engine oil pressure sensor
Faulty bypass valve
Damaged suction tube or cracked suction tube
Excessive wear of engine componentsRecommended Actions

Troubleshooting Test Steps Values Results
1. Engine Oil Level
A. Check the engine oil level in the crankcase. Refer to the Operation and Maintenance Manual for calibration of the dipstick gauge. The oil level can possibly be too far below the oil pump supply tube. The oil pump cannot supply enough lubrication to the engine components.
Oil
Result: The engine oil level is low.
Repair: Add engine oil to obtain the correct engine oil level. Refer to Operation and Maintenance Manual, "Engine Oil" for the recommendations of engine oil.
Start the engine. Inspect the exterior of the engine for oil leaks. Repair any oil leaks.
Result: The engine oil is not low.
Proceed to Test Step 2.
2. Aerated Oil
A. Sample the engine oil for aeration.
Foamy oil on the dipstick is a good indication of aeration.
Aeration
Result: The oil is aerated.
Proceed to Test Step 8.
Result: The oil is not aerated.
Proceed to Test Step 3.
3. Oil Viscosity
A. Sample the engine oil viscosity. Obtain an S O S Oil Analysis to determine the characteristics of the oil.
B. Access the "Cylinder Cutout Test" in the "Diagnostic Tests" under the "Diagnostics" menu.
C. Perform the "Automatic Cylinder Cutout Test" on Cat ET.
Oil Viscosity
Result: The oil viscosity is not correct.
Repair: Replace the engine oil.
Refer to Operation and Maintenance Manual, "Engine Oil" for the recommendations of engine oil. If the symptom is corrected, return the unit to service. If the symptom still exists, proceed to Test Step 4.
Result: The oil viscosity is correct.
Proceed to Test Step 4.
4. Oil Filter
A. Replace the engine oil filter.
Filter
Result: The oil filter was changed.
If the symptom is corrected, return the unit to service.
If the symptom still exists, proceed to Test Step 5.
5. Oil Pump
A. Manually check the engine oil pressure. Refer to Systems Operation/Testing and Adjusting, "Engine Oil Pressure - Test" for the correct procedure.
Oil Pressure
Result: The oil pressure meets specifications.
Proceed to Test Step 6.
Result: The oil pressure does
