Diagnostic Code
Description Conditions which Activate the Code System Response
100-1 Engine Oil Pressure : Low - most severe (3) The engine oil pressure has fallen below the trip point for the programmed delay time. The code is logged.
The red stop lamp is illuminated.
The engine is shut down.
100-17 Engine Oil Pressure : Low - least severe (1) The code is logged.
The amber warning lamp is illuminated. Probable Causes
Low engine oil level
Incorrect oil viscosity
Contaminated engine oil
Faulty oil pressure sensors
Improper circulation of the engine oil
Worn componentsRecommended Actions
Low Engine Oil Level
Check the oil level. Add oil to the engine, if necessary.Incorrect Oil Viscosity
Confirm that the oil in the engine has the correct viscosity. For information that is related to the correct viscosity of engine oil for your engine application, refer to Operation and Maintenance Manual, "Refill Capacities and Recommendations".Contaminated Engine Oil
Engine oil that is contaminated with another liquid will cause low engine oil pressure. A high engine oil level can be an indication of contamination. Obtain an analysis of the engine oil. Determine the reason for contamination of the engine oil and perform the necessary repairs. Change the engine oil and the engine oil filters. For information that is related to the correct engine oil for your application, refer to Operation and Maintenance Manual, "Refill Capacities and Recommendations".Faulty Engine Oil Pressure Sensors
Use Cat ET to check the status of the "Engine Oil Pressure" parameter while the engine is off. The reading should be close to zero pressure.If the reading is not comparable to zero, replace the suspect engine oil pressure sensor.Improper Circulation of the Engine Oil
Several factors could cause improper circulation of the engine oil:The engine oil filter may be clogged. Replace the engine oil filter, if necessary.Check that the oil filter bypass valve is not stuck in the open position. Clean the bypass valve or replace the bypass valve, if necessary.An engine oil line or a passage for engine oil that is obstructed can cause a low engine oil pressure. Inspect the oil lines for damage and/or for kinking.Check that the oil cooler bypass valve is not stuck in the open position. Clean the bypass valve or replace the bypass valve, if necessary.The engine oil cooler may be clogged. Thoroughly clean the engine oil cooler.There may be a problem with a piston cooling jet. Breakage, a restriction, or incorrect installation of a piston cooling jet will cause seizure of the piston. Inspect the condition of the piston cooling jets for each cylinder. Perform the necessary repairs.The inlet screen of the suction tube for the engine oil pump may be restricted. This restriction will cause cavitation and a loss of engine oil pressure. Check the inlet screen on the suction tube and remove any material that may be restricting the flow of engine oil.The suction tube for the oil pump could be drawing in air. Check the joints of the tube for a good seal or for a damaged O-ring seal. Check the tube for cracks. Perform the necessary repairs.Check for a
