Abstract
A novel apparatus, for determining the concentration of gas components in exhaust gas from a motor vehicle, features a lambda sensor element, an electric heater thermally coupled to the sensor element, a control unit regulating application of voltage to the heater, and at least two voltage sources which can be alternatively applied to the heater, as commanded by the control unit.
