Dont know anything specific on your Renault.
But ...
Earlier style inlet manifold (air intake) temp sensors are exactly the same type as the cooling water (engine temp) sensors : a rather clumpsy device with a large (12-14mm) thread to screw into the sensed media.
Usually seen as a large "bolt" style device screwed into the inlet manifold.
On many monopint injection systems the air temp sensor is a simple diode sensor fitted inside the the throttle body.
In any case these sensors are always 2wire sensors. But one wire MAY have been sacrificed due to the usage of the common earthing from the device screwed into its earthed metallic media.
When ever you find a candidate, you may check it by its ohmic resistance.
The ohmic value is most often to be found in 5K to 300 ohms, depending on temperature. The hotter the lower value.
They should of course never read high (disrupted) or shortcircuited.
