Engine Controls - System/Component Tests - 2.5L: Introduction
NOTE:
Testing procedures not covered in this article require a Chrysler Diagnostic Readout Box (DRB). See appropriate article in the ENGINE PERFORMANCE section below.
- TESTS W/CODES - 2.5L (for Dakota)
- TESTS W/CODES - 2.5L (for Caravan & Voyager)
Before testing individual components or systems, perform procedures in BASIC TESTING - 2.5L article in the ENGINE PERFORMANCE section. Since many computer controlled and monitored components set a fault message if they malfunction, also perform procedures in appropriate TESTS W/CODES article in the ENGINE PERFORMANCE section below.
- TESTS W/CODES - 2.5L (for Dakota)
- TESTS W/CODES - 2.5L (for Caravan & Voyager)
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.
