Codigos: OBD II - P2751 al P2900 |
| Relacion de codigos con 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 |
