Self Study Program 82 – Sensors in Skoda vehicles

VAG SSP 82. This brochure provides the user with theoretical information as well as practical information, where the measured variables and their measurement principles are described. Thus, it provides a complete overview of senders used in a particular unit and can at the same time be issued for all series type vehicles. New trends in the automotive industry require new modern technologies with high reliability, low production cost, miniaturization and high accuracy with minimal delay time.

The ever-increasing demands placed on vehicles are closely associated with the dynamic development of electronics and advanced technologies. There are new control and regulating functions available not only for the control of the engine and the chassis, but also in terms of security and comfort of the occupants. In connection herewith new electronic elements, called senders, measure scalar physical quantities and vector quantities. The main requirement here is that the signals from these senders and sensors are evaluated and processed within a very short time. The vehicle is therefore capable to react to outside influences in real-time or resolve crisis situations.

Or, in contrast, the code of the individual sender can be used in order to identify the unit or type of vehicle in which the sender is installed.
