Abstract

A pressure-measuring glow plug has a heating pin for igniting a combustion mixture of an internal combustion engine and a pressure sensor for detecting a combustion chamber pressure of the internal combustion engine. The pressure-measuring glow plug has a contacting unit which includes a carrier for accommodating a signal processing unit and a plug connection having connecting contacts in a plug housing. A glow module housing for accommodating the heating pin and the pressure sensor and an electronic module housing for accommodating the carrier are provided. The electronic module housing is connected at a glow module-sided connecting location to the glow module housing and, at a plug-sided connecting location, to the plug housing.
