Abstract: A diesel particulate filter is provided and may include a filter housing having an inlet and an outlet and a filter element disposed within the filter housing. A first metal conduit may be in fluid communication with an interior of the filter housing between the inlet and the filter element and a second metal conduit may be in fluid communication with the interior of the filter housing between the filter element and the outlet. A sensor assembly including a sensor housing may have a first port receiving the first metal conduit and a second port receiving the second metal conduit.

Abstract: A system for retaining a sensor on an injection molded intake manifold that uses a twist-lock connection within the receiving port. The sensor body has outwardly projecting lugs that pass between inwardly projecting lugs in the receiving port. The face of the manifold is formed with external guiding projections around the receiving port that direct insertion of the sensor into the receiving port in a specific first, unlocked orientation, and permit rotation of the sensor to a second, locked orientation. After the sensor is rotated to the locked orientation, attachment of an external connector, such as a wire harness, prevents the sensor from being rotated back to the first, unlocked orientation by interfering with the external guiding projections.
