Section 20 (Engine Controls - Tests W/O Codes - 5.8L EEC-IV): Introduction

1996 Ford RV Cutaway 5.8 HSECTION Introduction
WARNING: This page is about a different car, the 1996 Ford Pickup and 1996 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: This article covers 5.8L with Federal emissions and Gross Vehicle Weight (GVW) over 8500 lbs. For testing on all other 5.8L pickup models (EEC-V), see the TESTS W/O CODES - 5.8L EEC-V article.

Before diagnosing symptoms or intermittent faults, perform all BASIC DIAGNOSTIC PROCEDURES in BASIC TESTING - 5.8L article and SELF-DIAGNOSTIC TESTS in TESTS W/CODES - 5.8L EEC-IV article. Use this article to diagnose existing driveability problems when there are no trouble codes present.

NOTE: Some driveability problems may have been corrected by manufacturer with a revised Powertrain Control Module (PCM). Check with manufacturer for latest PCM application.

Symptom checks can direct the technician to malfunctioning component(s) for further diagnosis. A symptom should lead to a specific component or system test and/or adjustment.

Use intermittent test procedures to locate driveability problems that DO NOT occur when the vehicle is being tested. These test procedures should also be used if a continuous memory (intermittent) trouble code was present, but no problem was found during KOEO or KOER SELF-TEST.

NOTE: For specific testing procedures, see the SYSTEM/COMPONENT TESTS - 5.8L EEC-IV article. For specifications, see the ADJUSTMENTS - 5.8L or the SPECIFICATIONS - 5.8L article.
