Test NS-7B - Inspecting Idle Air Control Motor Operation

WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, and 1994 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: For circuit & connector terminal identification, see CONNECTOR IDENTIFICATION DIRECTORY . For wiring diagrams, see WIRING DIAGRAMS section. After each repair, perform TEST VER-1 .

Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. PCM is located under air cleaner. Inspect all terminals. Repair as required. If PCM terminals are okay, go to next step.
Using an external ohmmeter, check resistance of Gray/Red wire between IAC motor connector terminal No. 1 and PCM connector terminal No. 39. If resistance is less than 5 ohms, replace PCM. If resistance is more than 5 ohms, repair open Gray/Red wire.
