Engine Controls - System/Component Tests - 5.2L: Introduction

NOTE: Testing procedures not covered in this article require a Chrysler Diagnostic Readout Box II (DRB-II). See G - 5.2L TESTS W/ CODES article in the ENGINE PERFORMANCE Section.

Before testing individual components or systems, perform procedures in appropriate F - 5.2L BASIC TESTING article in the ENGINE PERFORMANCE Section. Since many computer controlled and monitored components set a fault message if they malfunction, also perform procedures in G - 5.2L 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.
