CODIGOS OBD II
P2000  al  P2050

RELACION O LISTA DE CODIGOS, DE NUMERACION QUE EMPIEZAN CON  : P2

La siguiente lista cubre todos los codigos P2 publicados hasta la fecha
Todos los codigos OBD-II que empiezan con P2, tienen un significado standard, independientemente de la marca o modelo del vehiculo
Recuerde: Los codigos que se reportan en la lectura, solo es un reporte de la funcion del sensor; de ninguna manera indica un cambio del mismo.
No caiga en la falsa tentacion de cambiarlo por uno nuevo, con la pretension de solucionar el problema.
Antes de ello; El mecanico debe hacer pruebas de funcionamiento para determinar un posible cambio.
Por lo regular los sensores acusan consecuencias. Ubicar el origen de la falla, es funcion del mecanico o persona calificada. [sistema electrico, electronico, alambrado o problemas basicos de funcionamiento del motor]
Los codigos que no empiezan con P2 ; puede ubicarlos en el siguiente enlace: OBD II
