Section 10 (Engine Controls - System & Component Testing): Introduction

WARNING: This page is about a different car, the 1994 Acura NSX and 1993 Acura NSX. However, it is still accessible from the selected car via links, so may be relevant.

Before testing separate components or systems, follow proper work flow. See 1993-94 SELF-DIAGNOSTICS article. If no Diagnostic Trouble Codes (DTCs) are present and a no start condition exists, proceed to 1991-94 BASIC DIAGNOSTIC PROCEDURES -- NSX article. If no DTCs are present and a driveability condition exists, proceed to 1991-94 TROUBLE SHOOTING -- NO CODES -- NSX article for diagnosis by symptom (i.e., ROUGH IDLE, ENGINE STALLS, etc.).

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.
