If these codes all appeared at -40f, I would wait until the warmer weather comes...very cold temps can do funny things to electrical sensors, so when it does get warm clear the codes , wait a week and see if they return, if the cars runs ok I wouldn't worry about it at the moment.....
Ps. Welcome to the Werkz..
