           In order to get an idea of the different types of sensors that are used in an engine let us take the example of a
           typical gasoline fuel injection system as shown in We can see that different sensors are used to detect crank shaft
           position, coolant temperature, engine speed, air flow rate, exhaust oxygen level, camshaft position, EGR valve
           position, exhaust manifold pressure, knock, manifold air pressure and manifold temperature.
           Shows a typical common rail diesel fuel injection system. In this case we have sensors for engine speed, air mass
           flow, crank speed, cam shaft position, turbo air boost pressure, fuel rail pressure, air temperature,
