Section 7 (Engine Control System & Engine Component Tests - 5.2L Engine): Introduction

WARNING: This page is about a different variant/trim than selected.

Before testing separate components or systems, perform procedures in BASIC TESTING - 5.2L V8 article. Since many computer-controlled and monitored components set a trouble code if they malfunction, also perform procedures in appropriate TESTS W/CODES - 5.2L V8 article.

NOTE: Testing individual components does not isolate possible short or open circuits. Unless stated otherwise in test procedure, perform all voltage tests with a Digital Volt-Ohmmeter (DVOM) having a minimum 10-megohm input impedance. Use ohmmeter to isolate wiring harness short or open circuits.
