Abstract: The invention relates to a temperature sensor (1) for a motor vehicle comprising:—a housing (3) defining an internal volume comprising a temperature sensitive element (5),—electrical wires (9) linked electrically to said temperature sensitive element (5) and configured to transmit an item of temperature information from said sensitive element (5) to the exterior of the housing (3),—a seal (13) partially surrounding the said electrical wires (9) so as to isolate the sensitive element (5) with respect to the exterior of the housing (3), the seal (13) extending preferably in a direction, termed the longitudinal direction.

Abstract: The invention relates to a motor-vehicle temperature sensor comprising a stop (13) designed to bear against a corresponding bearing surface delimiting a medium, the temperature of which has to be measured, and a means (15) for clamping the stop (13) against the bearing surface. According to the invention the stop (13) has a peripheral thickness (e) equal to or less than 1.2 mm and the clamping means (15) is made of a material having expansion properties common with the material of the bearing surface and is designed to compensate for the differences in expansion between the stop (13) and the bearing surface.
