Engine Controls - System/Component Tests - Gasoline: Introduction

NOTE: Testing procedures not covered in this article require a Chrysler Diagnostic Readout Box II (DRB-II). See appropriate G - TESTS W/ CODES article in the ENGINE PERFORMANCE Section.

Before testing individual components or systems, perform procedures in appropriate BASIC TESTING article in the ENGINE PERFORMANCE Section. Since many computer controlled and monitored components set a trouble code if they malfunction, also perform procedures in appropriate G - TESTS W/ CODES article in the ENGINE PERFORMANCE Section.

NOTE: Testing of individual components does not isolate possible shorts or opens in wiring harness of electronically controlled systems. Perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance unless otherwise instructed in procedure. Use an ohmmeter to isolate wiring harness shorts or opens.
