<\/a><\/h2>\nLa sonde lambda se situe entre le collecteur d\u2019\u00e9chappement et le catalyseur<\/strong>. Sur les nouveaux moteurs, deux sondes lambda sont install\u00e9es. La seconde se trouve apr\u00e8s le catalyseur<\/p>\n.<\/p>\n
Sonde lambda d\u00e9fectueuse, que faire\u00a0?<\/h2>\n
Le premier \u00e9l\u00e9ment \u00e0 prendre en compte est la possibilit\u00e9 pour votre calculateur de se mettre dans une configuration \u00ab\u00a0par d\u00e9faut\u00a0\u00bb<\/strong> en cas de sonde d\u2019oxyg\u00e8ne d\u00e9fectueuse<\/strong>. Le calculateur saura rep\u00e9rer si les informations transmises par la sonde sont incoh\u00e9rentes. Dans ce cas, il se mettra dans une configuration par d\u00e9faut comme le font les anciens moteurs pour permettre au v\u00e9hicule de fonctionner relativement correctement.<\/p>\nCependant, quelques signes avant-coureurs sont \u00e0 relever\u00a0: surconsommation, fum\u00e9es \u00e0 la sortie d\u2019\u00e9chappement, baisse de performances due \u00e0 un mauvais m\u00e9lange.<\/p>\n
On estime la dur\u00e9e de vie d\u2019une sonde lambda \u00e0 160 000 kilom\u00e8tres.
