Abstract
Disclosed herein is an impact absorber for an exhaust sensor. The impact absorber comprises a collar of deformable material disposed around a housing of the exhaust sensor. The collar extends radially outward from the housing. The collar may be formed from a material selected to degrade at exhaust temperature, or the collar may be formed from a material that provides radiation shielding to a portion of the sensor after installation. The collar may be disposed around a sealing gasket. A wall may be disposed around at least a portion of a perimeter of the collar, the wall being spaced apart from a plurality of facets formed on the housing to form a recess for receiving a socket wrench tool.
