I have a peugeot partner escapade. It doesn't have an external temp

Where do they usually position the sensor bulb on the car, to measure air
temperature it has to be positioned so that it is shielded from direct
sunlight, have exposure to clean air so to speak, and not be exposed to
engine heat. Any tips or ideas?

Under the front bumper is the usual place, though my manufacturers
built in one suggests the make some sort of compensation to the figure
displayed. What ever, it seems pretty accurate, with no variation even
when stood in traffic.
