Peugeot 206 2005 1.1 petrol - Engine running temp & pedal Sensor - Matt Kerrigan

Two queries:

The above car runs at 80deg C which I thought was low, just wondering if this is normal for this car. I wasnt able to connect to live data on my Memoscan U585 generic code reader to check temps. Previously at last service I think I could access this live data!!!

I serviced car and removed and cleaned throttle body after which EML come on and it was P0123 Pedal Position sensor A Circuit High Input. I reset codes and light stayed off but this code seems to be sitting in the background when I rescanned. Car is driving fine but just wondering if this is an indication of problem to come.

Appreciate any help.
