To understand whether or not a vehicle is functioning properly and determine its potential problems, a service provider now has to understand computers. This video offers guidance in the complex workings of a car's nerve center and the sensors that bring information, from mass air flow to engine coolant temperature, into an automotive computer system. Viewers can sharpen their skills and knowledge in interpreting real-time scan tool readings for cars that often boast over 50 microprocessors. Examples of modules that technicians frequently deal with are shown as the video discusses OBD II procedures and a variety of sensors, such as those for throttle position, heated oxygen, manifold absolute pressure, intake air temperature, and more.
