Section 183 (Engine Controls - System/Component Tests - 2.5L): Introduction

WARNING: This page is about a different car, the 1995 Jeep Wrangler and 1995 Jeep Cherokee. However, it is still accessible from the selected car via links, so may be relevant.

Before testing separate components or systems, perform procedures in BASIC TESTING - 2.5L article. Since many computer-controlled and monitored components set a trouble code if they malfunction, also perform procedures in TESTS W/CODES - 2.5L article in the ENGINE PERFORMANCE section.

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.
