Description and Operation



 
1--Fuel pressure sensor
2---Fuel supply manifold
3---Fuel injector retaining clip
4---Fuel injector O-ring seals
5---Fuel injector
6---Fuel pulse damper


The supply manifold is a fabricated plated steel rail with stamped cups for the injectors. The supply manifold is retained to the engine by two bolts.
The fuel pressure sensor is fitted directly onto the supply manifold and is retained by two bolts. Sealing is achieved by means of an O-ring seal.
The fuel injectors are fitted directly into the supply manifold and are retained by the supply manifold when assembled to the intake manifold. Sealing is achieved by means of upper and lower O-ring seals. The fuel injectors are activated sequentially by the powertrain control module (PCM) which modifies fuel quantity by adjusting fuel injector opening times according to the engine operating conditions.

Eclairage extérieur - Allumage automatique des phares Diagnostic et essais Se reporter au chapitre 417-01, du Manuel des schémas électriques pour les schémas et les informations sur les connecteurs. Outils spéciaux / Equipement d'atelier et outillage standard Kit de testeurs de bornes 29-011A Multimètre digital. Outil de diagnostic. Contrôle et vérification Note : Le module électronique générique (GEM) fait partie du boîtier électrique central (CJB). Note : Si le module GEM est remplacé, le module neuf doit être configuré après la pose. A cet effet, les données spécifiques au véhicule sont extraites du module à remplacer à l'aide de l'équipement de diagnostic et sont transférées dans le module neuf. Note : Avant d'extraire les données spécifiques au véhicule, s'assurer que toutes les connexions électriques du véhicule sont de nouveaux raccordées, de sorte que le module et l'outil de diagnostic puissent communiquer correct...
