Abstract
Se proporciona un método para monitorear un sensor de gases de escape acoplado a un escape del motor. En una realización, el método comprende indicar el deterioro del sensor de gases de escape en base a la forma de una distribución de valores extremos de una pluralidad de conjuntos de diferenciales lambda recopilados durante condiciones de funcionamiento seleccionadas. De este modo, es posible monitorear el sensor de gases de escape de manera no invasiva.
