Section 6 (Engine Controls - System/Component Tests - Turbo): Introduction

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

Before testing separate components or systems, perform procedures in appropriate article:

For 850 T-5, see TESTS W/CODES - MOTRONIC 4.3 - TURBO .
For 850 GLT, see TESTS W/CODES - MOTRONIC 4.4 - TURBO .

Since all monitored components set a Diagnostic Trouble Code (DTC) if they malfunction, see BASIC TESTING - 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.
