Abstract: An exhaust gas sensor assembly for a vehicle includes a sampling tube having a proximal end connectable to a housing and a distal end configured to be suspended with a cavity of the housing. The tube defines a hollow center, an inlet, an outlet, and an exhaust gas flow path extending from the inlet, through the hollow center, and to the outlet. An exhaust gas sensor is disposed in the hollow center at the proximal end and includes a sensing element disposed in the exhaust gas flow path. a flow guide is disposed in the hollow center between the inlet and the sensing element and is configured to redirect the flow path through a passageway defined between the tube and the flow guide.
