What is Crankshaft Sensor?
A Crankshaft sensor monitors the rotational speed of your crankshaft and sends this information into your car’s on-board computer. The on-board computer will then adjust fuel delivery and spark timing according to the information coming from the crankshaft sensor. This makes a crankshaft sensor an important part of your engine system as a bad crankshaft sensor affects not only the engine speed but also the fuel efficiency of your car. Aside from controlling the fuel injection process and ignition timing, crankshaft sensors are also responsible for your car’s emission performance, power output, reliability and driveability.A crankshaft sensor is composed of two parts - the rotating part and the static part. The rotating part is a toothed disc or wheel that rotates with the engine cam. The static part is the crankshaft sensor itself. There is also a crankshaft sensor equipped with LED lights and gets its reading as the LED light pass through the slots of a disc that is attached to a wheel.
