Este sensor es una parte esencial de cualquier coche, ya que asegura el correcto funcionamiento del motor. Cuando usted mira debajo del cap\u00f3 de su coche, puede tener problemas para encontrar el sensor. Normalmente, cada fabricante de coches tendr\u00e1 su ubicaci\u00f3n \u00fanica para colocar el sensor junto al motor. Puede encontrarse detr\u00e1s del silenciador, en el valle de elevaci\u00f3n del veh\u00edculo o junto al bloque motor.<\/h2>\n<p>&nbsp;<\/p>\n<h2><strong>\u00bfQu\u00e9 es un sensor de posici\u00f3n del \u00e1rbol de levas?<\/strong><\/h2>\n<p>&nbsp;<\/p>\n<p>El sensor de posici\u00f3n del \u00e1rbol de levas rastrea la rotaci\u00f3n del \u00e1rbol de levas, centr\u00e1ndose en el momento en que las v\u00e1lvulas se abren y se cierran. La mayor\u00eda de los sensores del \u00e1rbol de levas est\u00e1n situados justo encima del anillo dentado del \u00e1rbol de levas. La mayor\u00eda de estos sensores utilizan un im\u00e1n para generar o modificar una se\u00f1al el\u00e9ctrica de CA, que se utiliza junto con un sensor de posici\u00f3n del cig\u00fce\u00f1al para determinar cu\u00e1ndo una posici\u00f3n se aproxima al punto muerto superior (PMS) en la carrera de compresi\u00f3n. Estos datos ayudar\u00e1n a afinar la sincronizaci\u00f3n de la chispa y el pulso del inyector. Tambi\u00e9n se denomina sensor de identificaci\u00f3n de cilindros o detector de fase.<\/p>\n<p>La ECU en un sistema de inyecci\u00f3n de combustible secuencial debe decidir qu\u00e9 cilindro se dispara. El sensor de identificaci\u00f3n de cilindros proporciona esta informaci\u00f3n. Siempre que el primer cilindro se encuentra en el punto muerto superior durante la rotaci\u00f3n del motor, el sensor env\u00eda una se\u00f1al al controlador de a bordo (TDC).<\/p>\n<h2><strong>Funciones del sensor de posici\u00f3n del \u00e1rbol de levas (CAM):<\/strong><\/h2>\n<p>&nbsp;<\/p>\n<ul>\n<li>Para determinar qu\u00e9 cilindro se encuentra en la carrera de potencia, el ordenador de la m\u00e1quina utiliza un sensor para controlar la posici\u00f3n de rotaci\u00f3n del \u00e1rbol de levas con respecto a la posici\u00f3n del cig\u00fce\u00f1al.

Esta informaci\u00f3n es utilizada por el ECM para determinar la sincronizaci\u00f3n del encendido, as\u00ed como la sincronizaci\u00f3n de la inyecci\u00f3n de combustible requerida por el motor.
