Possible Causes:
1 Oil pressure sensor is inaccurate.
2 Fault simulation is enabled.
3 Threshold is set too high.
Diagnosis and Repair:
1 Check the oil pressure sensor accuracy with a mechanical oil pressure gauge.
Connect a mechanical oil pressure gauge of known quality and calibration to the engine at oneof the plugs on top of the oil filter head.
Connect InPower.
While the engine is stopped, compare the oil pressure reading on the service tool to the reading on the mechanical oil pressure gauge.
Only proceed if engine troubleshooting has been completed. Do not attempt to start the engineif there is doubt about the oil pressure.
Caution:
Do not attempt to start the engine if there is any doubt about the oil pressure, or thegenerator set may be damaged.
Start the generator set.
Compare the oil pressure reading on the service tool to the reading on the mechanical oilpressure gauge.
Refer to the troubleshooting and repair manual for the specific engine platform for oil pressureranges.
2 Fault simulation is enabled.
Connect to the control with InPower, and make sure that fault simulation for LOP is not enabled.
3 Threshold is set too high.
Using the electronic service tool, verify that the fault threshold is NOT within the normal operating range for the oil pressure sensor. Refer to the appropriate base engine manual for normal operating range.
