Idle Air Control Motor

Idle Air Control (IAC) motor is mounted on the throttle body and contains a 4-pin electrical connector. Individual component testing is not available from manufacturer. If IAC motor or wiring circuit failure exists, a Diagnostic Trouble Code (DTC) will be stored in Powertrain Control Module (PCM). See BASIC TESTING - 3.8L article. Since many computer-controlled and monitored components set a diagnostic trouble code if they malfunction, also perform procedures in appropriate TESTS W/CODES - 3.8L article.
