Information:
This engine is equipped with a Closed Crankcase Ventilation System (CCV) that is used for capturing fumes. The pressure sensor monitors the level of crankcase pressure. Fumes from the rear crankcase travel through the camshaft and exit the engine through the crankcase breather located at the front of the engine. The fumes from the crankcase breather are collected in the CCV. The engine oil is separated from the fumes from the crankcase in the filter. The engine oil collects in the filter and drains back to the crankcase through a drain line in the bottom of the filter. The fumes from the crankcase are directed back into the compressor inlet in order to be consumed by the engine. Refer to the Operation and Maintenance Manual for the replacement of the filter.Use this procedure in order to troubleshoot a high crankcase pressure. Also, use this procedure if one of the following diagnostic codes is active.
Table 1
Diagnostic Codes Table
J1939 Code and Description Conditions which Generate this Code System Response
101-15
Engine Crankcase Pressure : High - least severe (1) The crankcase pressure is higher than the trip point and the delay time has expired. The code is logged.
The ECM may derate the engine or shutdown the engine.
101-16
Engine Crankcase Pressure : High - moderate severity (2) Probable Causes
Engine oil
Plugged CCV system
Clogged CCV filter
Sensor
Engine componentsRecommended Actions
Note: The procedures have been listed in order of probability. Complete the procedures in the order of the listed test steps.
Table 2
Troubleshooting Test Steps Values Results
1. Check the Engine Oil Level
Oil Level
Result: The engine oil level is OK.
Proceed to Test Step 2.
Result: The engine oil level is high.
Repair: Troubleshoot and repair the cause of the incorrect oil level.
If the problem is not resolved, proceed to Test Step 2.
2. Check for Plugged CCV System or Clogged Filters
A plugged CCV system or clogged filter will cause excessive crankcase pressure.
Plugged Crankcase Breather
Result: The crankcase breathers are NOT OK.
Repair: Replace the fumes disposal filter according to the Operation and Maintenance Manual, "Engine Crankcase Breather - Clean".
Result: The crankcase breathers are OK.
Proceed to Test Step 3.
3. Check for a Faulty Pressure Sensor
A. Connect Cat® 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 and the atmospheric pressure in Cat ET.
Crankcase Pressure Sensor
Result: The crankcase pressure is within 3.5 kPa (0.5 psi) of the atmospheric pressure.
Proceed to Test Step 4.
Result: The crankcase pressure is not within 3.5 kPa (0.5 psi) of the atmospheric pressure.
Repair: Replace the crankcase pressure sensor.
If the problem is not resolved, proceed to Test Step 4.
4. 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 crankcase breathers. The crankcase breathers 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
