Section 12 (Engine Controls - System & Component Testing): Introduction

WARNING: This page is about a different car, the 2005 Acura NSX, 2004 Acura NSX, 2003 Acura NSX, and 2002 Acura NSX. However, it is still accessible from the selected car via links, so may be relevant.

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.

Before testing separate components or systems, follow proper work flow. See SELF-DIAGNOSTICS - NSX & NSX-T article. If no Diagnostic Trouble Codes (DTCs) are present and a no start condition exists, proceed to BASIC DIAGNOSTIC PROCEDURES - NSX & NSX-T article. If no DTCs are present and a driveability condition exists, proceed to TROUBLE SHOOTING - NO CODES - NSX & NSX-T article for diagnosis by symptom (i.e., ROUGH IDLE, ENGINE STALLS, etc.).
