    Hi

    1600 hours QSB 8.3 Maine Cummings
    Fault code came up 415 low oil pressure

    Cummings service tech changes sensor
    Same code
    Did a test on engine . Manual pressure gage read 40-50 psi! Good

    Engine idels 600 rpm
    Fault code comes up

    Pressure on smart craft reads 0.00 oil pressure 600 rpm, or 69.6 psi (on any other rpm )

    What was ultimate solution?

    Greetings!
    I am having the same issue with my QSC 8.3. New sensor being flown in today in my remote location (Shearwater, BC), but based on your post, I have low confidence in that being the solution. Any help would be appreciated!

    Maybe a QSC 8.3?

    If it makes you feel any better, the OP on your engine is very low by design.. Look at the attach specs for the newer “Q” engines..

    Leave manual gauge installed and run it.
    Qsl9 has same problem. New sensor won’t fix it. Be prepared for more false alarms to show up. Good luck.
