Impact protection of an exhaust sensor

An impact absorber for an exhaust sensor, the impact absorber comprising:

• a collar of deformable material disposed around a housing of the exhaust sensor, the collar extending radially outward from the housing, wherein the collar bends to absorb at least a portion of an impact force resulting from the exhaust sensor being dropped;
• wherein the collar is disposed around a sealing gasket, the sealing gasket being disposed around the housing.

An impact absorber for an exhaust sensor, the impact absorber comprising:

• a collar of deformable material disposed around a housing of the exhaust sensor, the collar extending radially outward from the housing, wherein the collar bends to absorb at least a portion of an impact force resulting from the exhaust sensor being dropped;
• wherein a wall is 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.

An exhaust sensor comprising:

• a housing;
• and, a collar of deformable material disposed around the housing, the collar extending radially outward from the housing, wherein the collar bends to absorb at least a portion of an impact force resulting from the exhaust sensor being dropped;
• wherein the collar is formed from a material selected to degrade at exhaust temperature.
