The Idle Air Control (IAC) valve on a 2002 Dodge Intrepid is located on the throttle body. It's a small, usually cylindrical component mounted directly on the throttle body itself. You'll need to look closely at the throttle body; it's often near the air intake side.
Because there are variations depending on the engine (2.7L, 3.2L, or 3.5L), a picture from a repair manual specific to your engine is recommended to be absolutely certain. Accessing it will likely require removing or at least loosening some air intake components.
