What is camshaft position sensor and how it works?

Camshaft position sensor monitors the position of the camshaft and transmits this data to the engines ECU. The on board computer system of the vehicle (ECU) works with several sensors and other devices to keep the engine running. Using data from the camshaft position sensor, the fuel injectors works and inject fuel when needed.

If camshaft sensor fails, the computer does not know when to trigger the injectors and may not trigger them at all, faulty or wrong readings from the sensor can also disrupt the timing of ignition, which will affect the fuel economy of the car. This sensor is used in conjunction with the crankshaft position sensor to control the ignition timing.
