For example, a âPC Expansion Cardâ maybe the jargon used to refer to any and all expansion cards (e.g., graphic, video, sound, etc.) for your âpersonal computer.â One may also come across references to âPCI.â The latter is not a card; it is one type of expansion slot into which the expansion card maybe installed in some computers.
Anyway, the best definition of what a Yaw rate sensor can be found here.... http://en.wikipedia.org/wiki/Yaw_rate_sensor\. In layman's terms it is a sensor that is located near the middle of the vehicle, under the center arm rest console, that detects if the car is moving or sliding sideways. Like going around a corner.
  The coolant temperature sensor is located on the passenger side radiator tank about 1/3 of the way down. It has a square back and faces toward the engine and is held in â¦ place by a spring clip. It has a two wire electrical connector and it is in direct contact with the radiator coolant via an o-ringed cylinder.
