The Febi camshaft position sensor is designed to keep an eye on engine speed and piston position in your BMW 330CI car. It delivers input signals to the ECM which are used to control fuel injection, ignition timing and other essential functions. The BMW Febi Crankshaft Position Sensor usually consists of rotor plate and a wave-forming circuit. The rotor plate has 360 slits for a 1°(POS) signal and 6 slits for a 120°(REF) signal; while the wave-forming circuit is composed of Light Emitting Diodes (LED) and photo diodes. The rotor plate is located in a place flanked by the LED and the photo diode. The LED sends out light to the photo diode. When the rotor plate turns, the slits cut the light to produce rough-shaped pulses where they are converted into on-off signals by the wave-forming circuit and then sent off to the ECM. The BMW Febi A4015-151788 is one of the best offerings in the market today. Its makers use the latest technology in design and manufacturing infusing innovation which proves helpful on the power train management system. It is usually made from top class materials to ensure great quality, durability, reliability and long service life. You can get the BMW 330CI Crankshaft Position Sensor you need through this website.
