Cummins ISB CM550 (1990-94) Fault Code: 415-SN PID: 100 SPN: 100 FMI: 1 Oil Pressure – Engine Protection
Circuit Description
The oil pressure sensor is used by the electronic control module (ECM) to monitor the
lubricating oil pressure. The ECM monitors the voltage on the signal pin and converts this to a
pressure value. The oil pressure value is used by the ECM for the engine protection system.
Component Location
The oil pressure sensor is located on the engine block below the ECM.
Shop Talk
Verify, with the driver, the engine speed at which the fault occurs. If the engine is being
operated at too low of a speed, the oil pressure can drop below the engine protection limits.
Possible causes:
1) Low oil level
2) Low operation speeds
3) Oil dilution
4) Oil filters change
