Beschreibung
Zusammenfassung:	The invention relates to a method for estimating the temperature of a gas pressure sensor attached to a wall of a turbocharged motor vehicle diesel engine, said sensor being positioned upstream of the turbine of the turbocharger. According to the invention, the temperature of the gas pressure sensor is estimated at least by measuring the temperature of the external air and the temperature of the wall to which the sensor is attached. L'invention se rapporte notamment à un procédé d'estimation de la température d'un capteur de pression de gaz fixé sur une paroi d'un moteur diesel de véhicule automobile suralimenté par un turbocompresseur, ce capteur étant positionné en amont de la turbine dudit turbocompresseur. Selon l'invention, cette estimation est réalisée au moins à partirde la mesure de la température de l'air extérieur et de la température de la paroi sur laquelle est fixé ledit capteur.
