A temperature sensor for a motor vehicle is disclosed. The temperature sensor includes a temperature-sensitive element, two electrical wires connecting the temperature-sensitive element to an electrical connector, an insulating sheath surrounding the two electrical wires, a protective endpiece including a closed end in which the temperature-sensitive element is housed, and a fixing means through which the insulating sheath passes. The fixing means has a threaded element to be screwed into a threaded orifice provided in a vehicle engine interface element to fix the temperature sensor to the engine interface element and a stop fixed to the insulating sheath. The stop surrounds the insulating sheath and provides sealing between the inside of the engine interface element and the outside, the threaded element being capable of rotating with respect to the stop. The stop comprises at least one lug that goes into a slot provided in the engine interface element to prevent the temperature sensor from rotating with respect to the engine interface element.

The invention relates to a temperature sensor () for a motor vehicle comprising:&#x2014;a housing () defining an internal volume comprising a temperature sensitive element (),&#x2014;electrical wires () linked electrically to said temperature sensitive element () and configured to transmit an item of temperature information from said sensitive element () to the exterior of the housing (),&#x2014;a seal () partially surrounding the said electrical wires () so as to isolate the sensitive element () with respect to the exterior of the housing (), the seal () extending preferably in a direction, termed the longitudinal direction. According to the invention, said sensor () furthermore comprises a guidance means () integral with said seal () for the guiding of said electrical wires () out of said sensor, said guidance means () lying in the extension of said seal () according to the longitudinal direction of said seal () from a central zone of the seal () towards the exterior of said sensor housing (), and the cross section of said guidance means () being of smaller dimension than that of the cross section of the seal (), at least one portion of said guidance means () lying outside the housing.
