Section 17 (Engine Controls - System/Component Tests - EFI): Introduction

WARNING: This page is about a different car, the 1990 Toyota Land Cruiser and 1989 Toyota Land Cruiser. 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 H - BASIC TESTING 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 .
