Section 86 (Engine Controls - System/Component Tests): Introduction
WARNING: This page is about a different car, the 1995 Mazda MX-3. 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 article. Since many computer-controlled and monitored components set a trouble code if they malfunction, also perform procedures in appropriate TESTS W/CODES article.
NOTE:
Testing individual components does not isolate shorts or opens. Perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance, unless stated otherwise in test procedure. Use ohmmeter to isolate wiring harness shorts or opens.
