Cummins isx sa 0 spn 102 fmi 18

Hello 2013 volvo with isx i have sa 0 spn 102 fmi code that keeps popping up. Heres what puzzles me , iv read what the code means and i have no symptoms. Truck still pulls as it should , mpgs are normal. Cac was changed, unrelated to the code. If i leave it alone it goes away on its on , i also have mini diagnostics tool i reset it , sometimes it doesnt come back in few days but it keeps coming back. i would appreciate any help
