Troubleshooting Test Steps    Values    Results    
1. Active Codes and Logged Codes
A. Establish communication between Caterpillar Electronic Technician (ET) and the Electronic Control Module (ECM).
B. Monitor the diagnostic codes on Cat ET. Check for active or logged diagnostic codes. Specifically check for codes that could be associated to low oil pressure. Refer to the histogram information for engine derates in Cat ET.
Note: Wait at least 30 seconds in order for diagnostic codes to become active.
C. If the histograms contain derates and no diagnostic codes are present, then the engine is operating normally.
   
Codes    
Result: A diagnostic code is present.
Repair: Troubleshoot any codes before continuing with this procedure.
Verify that the repair eliminated the problem.
Reset the histogram.
Result: A diagnostic code is not present.
Proceed to Test Step 2.
   
2. Engine Oil Level
A. Check the engine oil level in the crankcase. Refer to the Operation and Maintenance Manual, "Engine Oil Level - Check" for calibration of the dipstick gauge. The oil level can possibly be too far below the oil pump supply tube. The oil pump cannot supply enough lubrication to the engine components.
   
Oil    
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: Repair any oil leaks.
Verify that the repair eliminated the problem.
Result: The engine oil is not low.
Proceed to Test Step 3.
   
3. Aerated Oil
A. Sample the engine oil for aeration.
Foamy oil on the dipstick is a good indication of aeration.
   
Aeration    
Result: The oil is aerated.
Proceed to Test Step 9.
Result: The oil is not aerated.
Proceed to Test Step 4.
   
4. Oil Viscosity
A. Sample the engine oil viscosity. Obtain an S O S Oil Analysis to determine the characteristics of the oil.    
Oil Viscosity    
Result: The oil viscosity is not correct, or the oil is contaminated.
Repair: Replace the engine oil. Refer to Operation and Maintenance Manual, "Engine Oil" for the recommendations of engine oil.
Repair the cause of any engine oil contamination.
Result: The oil viscosity is correct.
Proceed to Test Step 5.
   
5. Oil Filter
A. Replace the engine oil filter.
   
Filter    
Result: Replace the engine oil filter.
Repair: The oil filter was replaced.
If the symptom is corrected, return the unit to service.
If the symptom still exists, proceed to Test Step 6.
   
6. Oil Pump
A. Manually check the engine oil pressure. Refer to Systems Operation/Testing and Adjusting, "Engine Oil Pressure - Test" for the correct procedure.
   
Oil Pressure    
Result: The oil pressure meets specifications.
Proceed to Test Step 8.
Result: The oil pressure does not meet specifications.
Repair: Replace the oil pump.
Verify that the repair eliminated the problem.
If the symptom still exists, proceed to Test Step 7.
   
7. Engine Oil Pressure Sensor
A. Remove the oil pressure sensor.
B. Install a pipe "T" in the pressure sensor port.
C. Install a manual gauge on one side of the pipe "T". Install the oil pressure sensor on the other side of the pipe "T".
D. Start the engine and compare the two readings. The pressure reading must be within
13.8 kPa ( 2 psi).
   
Sensor    
Result The pressure is within
13.8 kPa ( 2 psi).
Proceed to Test Step 8.
Result The pressure is not within
13.8 kPa ( 2 psi).
Repair: Replace the sensor.
Verify that the repair eliminated the problem.
If the symptom still exists, proceed to Test Step 8.
   
8. Engine Oil Filter Bypass
A. Replace the engine oil filter bypass valve.
   
Engine Oil Filter Bypass Valve
   
Result: The engine oil filter bypass valve was replaced.
If the symptom is corrected, return the unit to service.
If the symptom still exists. proceed to Test Step 9.
   
9. Oil Pump Suction Tube
A. Remove the oil pan.
B. Inspect the suction tube. Check the joints of the tube for cracks or for a damaged O-ring seal at the connection to the pump.
C. Inspect the inlet screen of the suction tube for a restriction. This restriction will cause cavitation and a loss of engine oil pressure.
   
Suction Tube    
Result: The suction tube and seal are OK.
Proceed to Test Step 10.
Result: The suction tube and seal are not OK.
Repair: Replace any damaged parts.
Verify that the repair eliminated the problem.
If the symptom still exists. proceed to Test Step 10.
   
10. Worn Engine Components
A. Remove the valve covers.
B. Inspect the camshaft and bearings.
C. Remove the oil pan.
D. Excessive clearance at the crankshaft or camshaft bearings will cause low engine oil pressure. Check the engine components for excessive clearance.
E. Inspect the piston cooling jets.    
Worn Parts    
Result: There are worn engine components.
Repair: Replace parts, if necessary. Check the Reuse and Salvage Guidelines for the reusability of existing engine components.
Verify that the repair eliminated the problem.
   If the procedure did not correct the issue, contact your Cat dealer Technical Communicator (TC). For further assistance, your TC can confer with the Dealer Solutions Network (DSN).
