Vacuum Diagrams: Introduction

This article contains underhood views or schematics of vacuum hose routing. Use these vacuum diagrams during the visual inspection in BASIC DIAGNOSTIC PROCEDURES article. This will assist in identifying improperly routed vacuum hoses, which cause driveability and/or computer-indicated malfunctions.

NOTE: Always refer to Emission Control label in engine compartment before attempting service. If manual and label differ, always use emission label specifications.
