Diagnostic Trouble Codes
J1939 Code CDL Code Description
(code descriptions may vary) Comments
101-0 E1036 (3) Engine Crankcase Pressure : High - Most Severe (3) 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.
101-15 E1036 (1) Engine Crankcase Pressure : High - Least Severe (1) 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.
101-16 E1036 (2) Engine Crankcase Pressure : High - Moderate Severity (2) 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 breather, or an obstructed hose. Probable Causes
Engine oil level
Faulty sensor
Internal engine problemRecommended Actions
Table 2
Troubleshooting Test Steps Values Results
1. Check the Engine Oil Level
A. Check the engine oil level.
Engine oil level
Result: The engine oil level is OK.
Proceed to Test Step 2.
Result: The engine oil level is high.
Troubleshoot the cause of the incorrect oil level.
2. Faulty Sensor
A. Connect Caterpillar Electronic Technician (ET) to the service tool connector.
B. Turn the keyswitch to the ON position. Do not start the engine.
C. Remove the oil filler cap.
D. Monitor the crankcase pressure in Cat ET.
Crankcase pressure sensor
Result: The crankcase pressure reading is 0 kpa (0 in of water) .5 kpa (2 in of water).
Proceed to Test Step 3.
Result: The crankcase pressure reading is not 0 kpa (0 in of water) .5 kpa (2 in of water).
Replace the crankcase pressure sensor.
3. Internal Engine Problem
Damaged pistons or rings can cause too much pressure in the crankcase. This condition will cause the engine to run rough. There will be more than the normal quantity of fumes (blowby) entering the OCV system. The OCV system can then more quickly become restricted, causing oil leakage at gaskets and seals that would not normally have leakage. Blowby can also be caused by worn valve guides or by a failed turbocharger seal.
A. To determine whether the piston rings leak, measure the crankcase blowby. Use the following service tools, along with Software License, NETG5044:
1. 285-0901 Blowby Tool Gp (LARGE ENGINE)
2. 348-5430 Multi-Tool Gp
Damaged or worn engine parts
Result: Crankcase Blowby is high, and there are worn or damaged engine parts
Repair or replace the worn or damaged parts.
Result: Crankcase Blowby is OK.
