Test TC-25D - Idle Air Control Motor Circuits

NOTE: Perform TEST TC-25A before proceeding.
NOTE: For connector terminal ID, see CONNECTOR IDENTIFICATION DIRECTORY  . For wiring diagram, see WIRING DIAGRAMS - 2.4L article.
  1. Ensure ignition is off. Disconnect connectors from Powertrain Control Module (PCM). The PCM is located between driver's side front fender and power distribution center, near battery.
  2. Inspect connectors for miswired or damaged terminals. If connectors are miswired or terminals are damaged, repair as necessary. Perform TEST VER-2A. If connectors are not miswired and terminals are not damaged, go to next step.
  3. Using external ohmmeter, check resistance between terminal No. 1 (Gray/Red wire) on connector for idle air control motor and PCM connector terminal No. 57 (Gray/Red wire). If resistance is less than 5 ohms, replace PCM. Perform TEST VER-2A. If resistance is 5 ohms or more, repair open circuit in Gray/Red wire between PCM and idle air control motor. Perform TEST VER-2A.
