You lick an ice cream, the nerves sense it and send the information to your brain, the brain sends the result back, and you say: it's cold and sweet. That is exactly where the idea of a camshaft position sensor came from. In fact, all sensors work that way. But when it comes to giving the on-board engine accurate information regarding the cam position, it is this sensor at work. There are two types of camshaft position sensor – the magnetic and Hall Effect sensor. The magnetic type of sensor is characterized with magnets and two-wire induction, while the Hall Effect is made up of three wires. No matter what type of sensor you choose, it does the same job of monitoring the position of the camshaft so it can give the engine computer concrete information on where in the four strokes of the engine it already is. By doing so, the on-board computer knows which cylinder should be injected with fuel-air mixture, compressed, or fired. A properly-working camshaft position sensor ensures proper engine operations. This results in efficient performance, and improved mileage. So make sure your vehicle is installed with a reliable one. And if the stock unit needs replacement, you can get one from Car Stuff. This online site guarantees easy camshaft position sensor acquisition to keep your engine computer from guessing which fuel injector to fire!
