Section 5 (Engine Controls - System & Component Testing): Introduction
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2002 Kia Sportage, 2002 Kia Spectra, 2002 Kia Sedona, 2002 Kia Rio, and 2002 Kia Optima. However, it is still accessible from the selected car via links, so may be relevant.
Before testing separate components or systems, perform procedures in BASIC DIAGNOSTIC PROCEDURES article. If system or component testing procedure is not cover in this article, and since many computer-controlled monitored components, or related control system circuits can set a trouble code if they malfunction, also perform procedures in appropriate SELF-DIAGNOSTICS article.
CAUTION:
When battery is disconnected, vehicle computer and memory system may lose memory data. Driveability problems may exist until computer system have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery.
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.
NOTE:
For assistance on component harness connectors wire color(s) and pin connector number(s), see appropriate wiring diagram under ENGINE PERFORMANCE in WIRING DIAGRAMS.
