Section 12 (Engine Controls - System/Component Tests - Non-Turbo): Introduction

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

Before testing separate components or systems, perform basic diagnostic procedures in BASIC TESTING - NON-TURBO article. Since all monitored components set a Diagnostic Trouble Code (DTC) if they malfunction, see appropriate article:

For 850 Non-TLEV (A/T), see TESTS W/CODES - MOTRONIC 4.3 - NON-TURBO .
For 850 (M/T), 850 TLEV and 850R, see TESTS W/CODES - MOTRONIC 4.4 - NON-TURBO .

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