System Schematic For Engine Oil Pressure Sensor (EOPS) On EIS Controlled EnginesTo find the cause of a low oil pressure shutdown, perform this procedure.Test Step 1. CHECK FOR A DIAGNOSTIC CODE.
Check for a CID 0100 (oil pressure sensor) or CID 0269 (sensor power supply) diagnostic code that is active. (On engines with an ECM, check for a CID 100 E diagnostic code.) See System Operation, "Diagnostic Codes".Expected Result:CID 0100 or CID 0269 should not be showing (active).Results:
OK - A CID 0100 or CID 0269 is not showing. Proceed to Test Step 2.
NOT OK - A CID 100 or CID 269 is active.Repair: Correct the active CID 100 or CID 269 prior to proceeding with this procedure. See System Operation, "Diagnostic Codes". Stop.Test Step 2. CHECK OBVIOUS CAUSES.
Check for low oil pressure.
Check the oil level.
Check for oil leaks.
Check for other obvious causes of low oil pressure.Expected Result:No obvious cause should exist.Results:
OK - No obvious causes for low oil pressure exist. Proceed to Test Step 3.
NOT OK - An obvious cause does exist.Repair: Correct the problem. Refer to the Engine Service Manual. Stop.Test Step 3. CHECK SETPOINTS.This step checks the setpoints P012 (oil step speed), P013 (low oil pressure at rated speed) and P014 (low oil pressure at idle speed).
View setpoints P012, P013 and P014. Make a note of the values for these setpoints. See System Operation, "Engine/Generator Setpoint Viewing OP2-0".
Compare the setpoints that were noted with the specified setpoints of the particular generator set.Expected Result:The setpoint value that was noted and the specified setpoint value should agree.Results:
OK - The setpoints agree. Proceed to Test Step 4.
NOT OK - The setpoints do not agree. Repair: Reprogram setpoints P012, P013 and P014. See System Operation, "Engine/Generator Programming OP5-0". Stop.Test Step 4. CHECK THE LOW OIL PRESSURE FUNCTION.
Turn the engine control switch (ECS) to the OFF/RESET and then turn the switch to the START.
Allow oil pressure to stabilize after the engine has started.
When the engine is at idle speed, compare the actual pressure that is showing on the lower display with the setpoint P014. The actual pressure that is showing on the lower display should be greater than setpoint P014.
When the engine is at rated speed, compare the actual pressure that is showing on the lower display with the setpoint P013. The actual pressure should be greater than setpoint P013.Expected Result:The actual pressure at idle speed and at rated speed should be greater than the respective setpoint value. These actual pressures should not cause a low oil pressure shutdown.Note: It may be necessary to check the accuracy of
