Abstract
Herein disclosed is an apparatus by which an exhaust gas sensor is placed in flow communication with the exhaust gases issued from an engine. The apparatus is so constructed and arranged such that a volume of air is maintained about a body portion of the exhaust gas sensor in heat conductive relation with the exhaust gases. The apparatus may be provided with a heater around a probe portion of the exhaust gas sensor which projects into the exhaust conduit. The heater is selectively energized to heat the probe portion when the temperature of the exhaust gases is low.
