CAP-BEARING 6F3183 - Caterpillar

The engine is equipped with an open crankcase ventilation (OCV) system. Refer to Illustration 1. The pressure sensor monitors the level of crankcase pressure. The OCV system contains a filter element. Tubing routes the blowby from the OCV system to the filter housing. The filter housing contains a filter element. The filter element filters the blowby. Refer to the Operation and Maintenance Manual for the replacement of the filter.Troubleshooting ProcedureReset all active codes and clear all logged codes.Use this procedure in order to troubleshoot a high crankcase pressure or use this procedure if one of the following diagnostic codes is active.

Diagnostic Trouble Codes    
CDL Code    J1939 Code    Description
(code descriptions may vary)    Comments    
E1036 (1)     101-15     Engine Crankcase Pressure : High - Least Severe     The Engine Control Module (ECM) activates this code when the crankcase pressure has exceeded the limit for a programmed time period. The amber warning lamp is illuminated. The code is logged. Engine power is derated.
This code can be caused by an obstructed tube, an obstructed filter, or an obstructed hose. Also, a plugged OCV system will cause the code.    
E1036 (2)     101-16     Engine Crankcase Pressure : High - Moderate Severity     The ECM activates this code when the crankcase pressure has exceeded the limit for a programmed time period. The amber warning lamp is illuminated. The code is logged. Engine power is severely derated.
This code can be caused by an obstructed tube, an obstructed filter, or an obstructed hose.
Also, a plugged OCV system will cause the code.
