    No I replaced the engine and the machine lost all digging power. Got pressures set and it has power to dig but cycle times are extremely slow. Did not know if there is a sensor associated with any of these codes that would effect that.

    If you changed the engine you will need to carry out an A-adjustment to re calibrate everything back together correctly. Unless those faults are flashing on the screen they will have no effect on the machine performance.
    What is your engine max rpm and cycle times
