According to the Volvo green book on Motronic 4.4, P0116 is the fault code generated by Engine coolant temperature (ECT) sensor. Your ECT sensor could be dead (or dying), or maybe one of the cables is grounded somewhere. What's the mileage of your car?
I don't know what P0455 code means. It's not in the Motronic 4.4 green book. My guess is that this fault was generated by another electronic system of your car (for example, AT box). Maybe somebody else here will tell you the description of the fault. Good luck
