Too late now but depending on the year and model they do have computer for the PS.
There are 2 types of PS system, speed sensing and rpm sensing.

computer is to the left of your feet and up under the instrument cluster area of the driver's side. its a little *** thing.
as for p/s not liking to work when it's cold, instead of using p/s fluid try using ATF, atf is thinner and more resistent to sludging up when its real cold. P/S fluid gets super thick when its cold out which overworks the pump and makes the steering feel more difficult.
hell mazda's P/S Fluid is ATF now, Mercon V to be exact.

Truck fleets use ATF in big hydraulic applications where temperature drops low, for the reason Kevin said. Less pump effort and faster operation, even at minus 30. ATF performs much better in the cold. I've seen systems that come from another country and they ask "hydraulic fluid only", and we use them up in Canada pumping ATF instead (because of the cold in winter), lasting years without any type of failure (other than mechanical abuse, not fluid related).
Before anybody goes to get a new pump or a new rack or computer, change the fluid first. Chances are it hasn't been changed in a long time if at all, and it's burnt to ****. Disconnect the return line and steer lock to lock. Refill and look for improvement. P/S, ATF, whatever available is than the garbage in the reservoir you got now.
