Abstract: The invention relates to a device for determining the pressure and temperature in the suction pipe of an internal combustion engine with a temperature sensor (50) and pressure sensor (30) positioned in a common housing (10), said pressure sensor being fixed on a support (20), together with an evaluating circuit, with as few distortions possible. The aim of the invention is to improve the device in such a way that it is easy to produce and enables temperature to be measured precisely and especially pressure to be measured very precisely. To this end, it is suggested that a connection piece (40) attached to the housing (10) is provided for delivering a medium under pressure, as well as an intermediary piece (60) which is connected to both the support (20) and said connection piece (40) via seal bonds (61), said seal bonds neutralising mechanical distortions.
