outside temperature sensor reading -40 censius???

[Big Load]

hi
i've been away and busy as usual with work things so never had much time to work on my car.
so far i have had the MAF changed, timing belt and water pump changed, flex plate checked and adjusted. now i need some help on the following:

1. I noticed on my dash the outside temperature is reading -40 !!!!!?? whats up with that.
can someone please explain is this sensor just sensing the outside temperature or does it do anything special ?? the fact that it is reading -40 i think it means its working ?? maybe

2. Also i need some help in finding some screws for the front spoiler and wheel arches. does any one have any i can buy from them or let me know where to buy them from. I have been looking but cannot find them except with porsche.

3. is the steering supposed to be heavy to turn? mine is tight and squeeks a bit.

and obviously please if there is a thread regarding these points pls direct me to them. thanks

i had to link this guy into our threads he is very good at helping diagnosing issues and his videos are idiot proof so far.
