The Idle Air Control (IAC) valve on a 2000 Kia Sportage is located on the
throttle body. The throttle body itself is usually found at the top of the engine, where the air intake tube connects to the engine. The IAC valve is a small component often mounted directly on the throttle body; it's usually cylindrical and may have a single electrical connector attached.
However, visual identification can be tricky. It's best to consult a repair manual specific to your 2000 Kia Sportage's engine (likely a 2.0L or a 2.5L) for a diagram showing the exact location and appearance of the IAC valve. Online diagrams or forums specific to that model year and engine will also be helpful.
