Test TC-28B - Idle Air Control Motor Circuits

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-2 .

Turn ignition off. Disconnect and inspect Powertrain Control Module (PCM) connector. PCM is located under air cleaner. If any terminals are damaged, pushed out or miswired, repair as necessary. If PCM connector is okay, go to next step.
Using DRB in ohmmeter mode, check resistance of PCM connector terminal No. 39 (Gray/Red wire). If resistance is less than 5 ohms, repair short to ground in Gray/Red wire. If resistance is more than 5 ohms, replace PCM.
