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.

An unheated planar sensor element for determining the concentration of a gas component in a gas mixture, in particular the oxygen concentration in the exhaust gas of an internal combustion engine, has a sensor foil made of a solid electrolyte with an outer electrode exposed to the measuring gas, and an inner electrode exposed to a reference gas, as well as a reference-gas channel, which is covered by the sensor foil on one side and accommodates the inner electrode. To produce a small-volume, cost-effective unheated sensor element for use in small combustion engines having low power output yet sufficiently satisfactory measuring accuracy, the reference-gas channel is sealed on the underside by an additional sensor foil made of a solid electrolyte, and covered by an inner electrode lying inside the reference-gas channel and an outer electrode exposed to the measuring gas.

A replacement kit for replacing an electrical device coupled to a vehicle via a plurality of vehicle lead wires. The replacement kit includes a replacement electrical device, a plurality of lead wires extending from the replacement electrical device, and a housing assembly for protecting a spliced connection formed with the lead wires to create an electrical connection between the electrical device and the vehicle. The housing assembly includes a base having a plurality of individually isolated bores extending therethrough. Each bore is capable of housing a spliced connection of a respective vehicle lead wire and a respective replacement electrical device lead wire, and each bore has therein a plurality of seal rings to form a substantially water-tight seal around the associated portion of the spliced connection. The housing assembly also includes a cap secured to the base. Preferably, the electrical device and the replacement electrical device are oxygen sensors.
