Checking Idle Air Control Motor

NOTE: For circuit identification and wiring diagram, see WIRING DIAGRAMS article. After each repair procedure has been completed, reconnect all components. Perform POWERTRAIN VERIFICATION TEST VER-2  under VERIFICATION TESTS to ensure system is functioning properly.
  1. Start engine an allow it to reach normal operating temperature. Using scan tool, actuate Idle Air Control (IAC) motor to 1400 RPM. If engine speed does not increase to 1400 RPM, go to next step. If engine speed increased to 1400 RPM, stop actuation. IAC motor is operating properly this time. Test is complete.
  2. Turn ignition off. Disconnect IAC motor connector. IAC motor is located on throttle body. Visually inspect connector for corroded, damaged, pushed-out or miswired terminals. Repair connector and terminals as necessary. If connector and terminals are okay, go to next step.
  3. Ensure ignition is off. Disconnect PCM connectors. On Cherokee, PCM is located in engine compartment on left front fender, near radiator support. On Grand Cherokee and Wrangler, PCM is located on firewall in right rear corner of engine compartment. On all models, inspect connectors for damaged pins, corrosion and loose terminals. Repair connectors as necessary. If connectors are okay, measure resistance of each wire between IAC motor harness connector and PCM C1 harness connector. See WIRING DIAGRAMS article. See Figure or Figure . If each resistance is less than 5 ohms, replace IAC motor. If any resistance is 5 ohms or more, repair open in appropriate wire between IAC motor and PCM.
