Abstract
A closed loop mixture control system for an internal combustion engine of a motor vehicle is provided with a voltage divider connected across the terminals of a single source of DC potential mounted on the vehicle to develop an offset voltage which is combined with the output of an exhaust gas sensor having a bipolar output characteristic. One of the polarities of the exhaust gas sensor output is compensated for by the offset voltage.
