SPRING (Outer) 3P4435 - Caterpillar

Use this procedure to troubleshoot low engine oil pressure. Use this procedure for one of the codes in Table 1.
Table 1
Diagnostic Trouble Codes
CDL Code and Description Comments
E360 (3)
Low Engine Oil Pressure - most severe (3) Oil pressure is lower than the specified pressure for at least 4 seconds. Engine will "Shut down". A snapshot is triggered. The code is logged. Factory passwords are required.
The ECM will only "Shut down" the engine if the "Engine Monitoring Mode" parameter is programmed to "Shut down".
E360 (1)
Low Engine Oil Pressure - least severe (1) 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.
E360 (2)
Low Engine Oil Pressure - moderate severity (2) Oil pressure is lower than the specified pressure for at least 8 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. Check the 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.
Engine oil level
Result: The engine oil is OK.
Proceed to Test Step 2.
Result: The engine oil level is NOT OK.
Repair: Add engine oil in order 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.
If the problem is not resolved, proceed to Test Step 2.
2. Check for Aeration of the Engine Oil
A. Sample the engine oil for aeration.
Note: Foamy oil on the dipstick is a good indication of aeration.
Aeration
Result: The oil is OK.
Proceed to Test Step 3.
Result: The oil is NOT OK.
Proceed to Test Step 8.
3. Check the Oil Viscosity
A. Sample the engine oil viscosity. Obtain anS 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" in Cat® Electronic Technician (ET).
Oil Viscosity
Result: The oil viscosity is OK.
Proceed to Test Step 4.
Result: The oil viscosity is
