With an ever growing automotive technology it can be difficult to keep up with all the new sensors that the manufacturers develop. As these newly developed engine sensors may improve gas mileage it can sometimes be difficult to understand what they do exactly.
We wondered the same thing and fortunately we found a website that is dedicated to just that and its all about Automotive Engine Sensors. You can learn what these sensors are and how they function. If you have a desire to know where they are located on the engine, they have that too. I have found this resource quite educational and the illustrations helpful in understanding a bit more about what is going on and where the sensors are located.
