ABSTRACT:
An insulation bushing assembly for use with an exhaust gas sensor. The insulation bushing assembly includes an insulation bushing having a passageway defining a surface, and a contact plate assembly having a contact plate coupled with the insulation bushing. A resilient member extends from the contact plate and into the passageway. The resilient member is engageable with the surface of the passageway such that the member is deflected by the surface from an undeflected position with respect to the contact plate to a deflected position with respect to the contact plate to retain the contact plate assembly in engagement with the bushing.
