Le diagnostic des performances de la gaine de protection du capteur de particules peut d\u00e9clencher un faux code d’anomalie P1488 (circuit haute tension de temp\u00e9rature du capteur de particules) sur certains camions Silverado et Sierra 2020 \u00e9quip\u00e9s du moteur diesel Duramax de 3,0 litres (EFC LM2). Le t\u00e9moin d’anomalie du moteur (MIL) peut \u00e9galement \u00eatre allum\u00e9.<\/p>\n

Si le code d’anomalie P1488 est m\u00e9moris\u00e9, v\u00e9rifiez si le capteur de particules n’est pas desserr\u00e9 dans le tuyau d’\u00e9chappement. Si le capteur de particules est desserr\u00e9, suivez les diagnostics dans les informations de service appropri\u00e9es.<\/p>\n

Si le capteur de particules est correctement serr\u00e9 et que le code d’anomalie P1488 est m\u00e9moris\u00e9, testez l’\u00e9tanch\u00e9it\u00e9 de l’\u00e9chappement \u00e0 l’aide du d\u00e9tecteur de fuites GE-52250 Power Smoke Diagnostic.<\/p>\n

R\u00e9parez les fuites au besoin et remplacez le capteur de particules.<\/p>\n

Si le joint illustr\u00e9 fuit (Fig. 23), il se peut que le collier ait atteint le fond avant qu’une charge de serrage suffisante ne soit appliqu\u00e9e au joint. (Fig. 24) Le collier doit alors \u00eatre remplac\u00e9.<\/p>\n
