WATER INTRUSION COVER FOR SENSOR PROBE

A water intrusion cover for a sensor probe in an exhaust system is provided. The water intrusion cover includes a main body portion having a substantially cylindrical shape, an inlet opening, and an outlet opening. The inlet opening and outlet opening are formed in a sidewall of the main body portion and are fluidly coupled to form a continuous flow path defined by a surface that, in a cross-section perpendicular to an axis of the main body portion, curves from the inlet opening to the outlet opening. The water intrusion cover further includes a shoulder portion having a substantially cylindrical shape. The main body portion and the shoulder portion collectively define a central passage for the sensor probe.
