PLUG 2D2182 - Caterpillar

Use this procedure in order to troubleshoot low engine oil pressure. Also, use this procedure if one of the following event codes is active.
Table 1
Event Codes
CDL Code and Description Conditions which Generate this Code System Response
E360(1) Low Engine Oil Pressure The engine oil pressure is below the map-based trip point and the delay time has expired. The code is logged.
E360(3) Low Engine Oil Pressure The code is logged.
The engine is shut down. If the engine shuts down due to a low oil pressure, power to the Electronic Control Module (ECM) must be cycled before restarting the engine.Probable Causes

Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Caterpillar Electronic Technician (ET) to the service tool connector. Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Download the "Product Status Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
C. Determine if the event code that directed to this story is present.
D. Look for active diagnostic codes that are associated with the system for the event code that directed to this story.
E360
Result: An associated code is present.
Repair: Troubleshoot any associated codes before continuing with this test.
Result: An E360 code is present.
Proceed to the next step.
Result: No active codes

2. Check the Engine Oil Level
Level
Result: The engine oil is not low.
Proceed to the next step.
Result: The engine oil level is low.
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 the next step.
3. Ensure that the Oil Viscosity is Correct
For the correct engine oil to use, refer to the Operation and Maintenance Manual. Viscosity
Result: The engine oil is of the correct type.
Proceed to the next step.
Result: The engine oil is not of the correct type.
Repair: Determine the reason why incorrect oil is in the engine.
Change the engine oil and the engine oil filter
If the problem is not resolved, proceed to the next step.
4. Check for Contaminated Engine Oil
A. Obtain an analysis of the engine oil.
High engine oil level can be an indication of contamination with fuel or coolant. Engine oil that is contaminated with another liquid will cause low engine oil pressure.
Contamination
Result: The oil is not contaminated.
Proceed to the next step.
Result: The oil is contaminated.
Repair: Determine the reason for contamination of the engine oil and make the necessary repairs.
Change the engine oil and the engine oil filter
Refer to Operation and Maintenance Manual, "Engine Oil" for the recommendations of engine oil.
If the problem is not resolved, proceed to the next step.
5. Check the Oil Pressure Sensors
A. Use the Cat ET to compare the readings of the following:
- Unfiltered Oil Pressure (abs)
- Engine Oil Pressure (abs)
