Abstract
A method of manufacturing an exhaust temperature sensor is disclosed. It includes forming a green ceramic substrate; and printing an electrical circuit on the green ceramic substrate. The method then contemplates trimming the electrical circuit to a predetermined resistance prior to firing the green ceramic. Finally, the method contemplates firing the green ceramic substrate with the electrical circuit thereon.
