Section 7 (Engine Controls - System/Component Tests): Introduction

WARNING: This page is about a different car, the 1990 Saab 9000 and 1990 Saab 900. 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 TESTS W/CODES article.

NOTE: Testing of individual components does not isolate possible shorts or opens. Perform all voltage tests with a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance, unless stated otherwise in testing procedures.
