Chrysler 300M temperature guage

Just in the last few weeks my 300M's outside temperature reading is
occasionally stuck at 17°C after the car has been parked. This is a
random occurrence, but it's always showing 17° when stuck.

Today it happened again and didn't unstick until I returned home, turned
the ignition off, then on again.
The actual temperature today was around 25°C.
TIA for any ideas.

I believe that the sensor is right behind the grill in front of the rad.. A
quick and dirty test is to
go to a wrecking yard and get another sensor and replace it then see if that
fixes the problem
