Certains mod\u00e8les Silverado, Sierra 2019-2021, Tahoe, Suburban, Yukon et Escalade 2021, \u00e9quip\u00e9s du moteur 5.3L (EFC L84) ou 6.2L (EFC L87), (Fig. 19) peuvent m\u00e9moriser n’importe quel code d’anomalie, parmi les suivants\u00a0:<\/p>\n

Code d’anomalie\u2009P3189 – Charge d’\u00e9chappement haute pression captur\u00e9e dans le cylindre\u00a01<\/p>\n

Code d’anomalie\u2009P318A – Charge d’\u00e9chappement haute pression captur\u00e9e dans le cylindre\u00a02<\/p>\n

Code d’anomalie\u2009P318B – Charge d’\u00e9chappement haute pression captur\u00e9e dans le cylindre\u00a03<\/p>\n

Code d’anomalie\u2009P318C – Charge d’\u00e9chappement haute pression captur\u00e9e dans le cylindre\u00a04<\/p>\n

Code d’anomalie\u2009P318D – Charge d’\u00e9chappement haute pression captur\u00e9e dans le cylindre\u00a05<\/p>\n

Code d’anomalie\u2009P318E – Charge d’\u00e9chappement haute pression captur\u00e9e dans le cylindre\u00a06<\/p>\n

Code d’anomalie\u2009P318F – Charge d’\u00e9chappement haute pression captur\u00e9e dans le cylindre\u00a07<\/p>\n

Code d’anomalie\u2009P3190 – Charge d’\u00e9chappement haute pression captur\u00e9e dans le cylindre\u00a08<\/p>\n

Dans le syst\u00e8me de d\u00e9sactivation de cylindre, les poussoirs d’admission et d’\u00e9chappement sont d\u00e9sactiv\u00e9s cons\u00e9cutivement, de telle mani\u00e8re qu’une charge basse pression est captur\u00e9e dans le cylindre. En cas de d\u00e9faillance m\u00e9canique du train de soupape, une charge haute pression peut \u00eatre captur\u00e9e dans le cylindre, ce qui provoque la m\u00e9morisation d’un code d’anomalie.<\/p>\n

En examinant ces codes d’anomalie dans les informations d’entretien (SI), il peut \u00eatre difficile d’isoler le probl\u00e8me et le cylindre correct. Le probl\u00e8me peut \u00eatre d\u00fb \u00e0 un cylindre de la rang\u00e9e oppos\u00e9e \u00e0 l’emplacement du code d’anomalie.<\/p>\n

Examiner la rang\u00e9e de l’autre c\u00f4t\u00e9 du moteur, en recherchant tout probl\u00e8me de train de soupape associ\u00e9 \u00e0 ces codes d’anomalie.<\/p>\n
