    Asi traducido con mi ingles de primaria XD parece que es un sensor de picado, lleva 2, pero los dos estan por delante del bloque asi que no sea a cual se refiere diciendo "rear".
    Igual no es eso eh, pero a eso me suena, voy un momento al coche y miro en el listado que tengo alli de los fallos.

    Si buscas en google knock sensor salen fotos de sensores de picado asi que por ahi andan los tiros.

    Son estos dos que ves en los circuos rojos grandes, estan debajo de los colectores de admision.




    En mi listado de fallos dice "signal missing o fautly" asi quye revisa primero los conectores y tal y cual.

    P.D: en que pin viste el fallo por que en el A2 hay otro 433 que es la sonda lambda

    Al salirme el fallo 121 y cambiar el cauda e ir igual y no apagarse el fallo,doy mas credito a que sea la sonda 433 esa tuya.De todas formas si noto que abajo parece que pica...pero esos sensores no son faciles de ver por lo que veo.

    Si no recuerdo mal uno se podia llegar a ver, e incluso sacar, no sin esfuerzo pero creo que si que se podia, el otro imposible ya que queda detras del PCV. Todo esto por debajo del coche

    Mira tambien la lambda si no la tienes cambiada desde hace mucho, imagino que sera como la mayoria de los coches, 4 cables, 2 grises, 1 blanco y 1 negro. Con un polimetro, entre el blanco y el negro hay 12v ( tension bateria vamos) y entre los dos grises tiene que fluctuar todo el rato entre 0,1 y 0.9v, esto ultimo tiene que ser con el coche encendido.

    Aunque en nuestros coches creo que la lambda tiene su propio testigo en el cuadro, creo.

    el testigo que llevo encendido es el famoso triangulo amarillo.He intentado quitarlo desconectando la bateria,pero permanece eterno.Hay otra manera de resetearlo?
