Checking Idle Air Control Motor
NOTE:
For circuit and connector terminal identification, see CONNECTOR IDENTIFICATION. For wiring diagrams, see WIRING DIAGRAMS - 2.5L FLEXIBLE FUEL
article.
Turn engine off. Disconnect Powertrain Control Module (PCM) connector. Using an external ohmmeter, check resistance on each wire between Idle Air Control (IAC) motor connector and PCM connector. See PCM TERMINAL IDENTIFICATION table. If resistance for any wire was more than 5 ohms, repair open on necessary wire. Perform TEST VER-2. If resistance for all wires was less than 5 ohms, replace PCM. Perform TEST VER-2.
