A sensor assembly for use in a vehicle. The sensor assembly has a housing for receiving a substrate. Terminals with substrate mating portions are provided in the housing. The substrate has components mounted thereon and plated openings which extend therethrough. The plated openings are provided in electrical engagement with the terminals. The openings are provided to mechanically and electrically engage the resilient contact portions of the terminals. The substrate mating portions are releasably pressure fit within the plated openings to allow the substrate to be removed and replaced as needed. The substrate mating portions maintain the electrical and mechanical connection between the substrate mating portions and the plated openings when the sensor assembly is exposed to vibration.
