Section 16 (Engine Controls - System/Component Tests - EFI): Introduction

WARNING: This page is about a different car, the 1990 Toyota Camry and 1989 Toyota Camry. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Prior to testing separate components or systems, it is highly recommended that all procedures listed in BASIC TESTING - EFI be performed. Since many computer controlled and monitored components will set a trouble code if they malfunction, it is also recommended that self diagnosis be performed. See TESTS W/CODES - EFI .
