Idle Air Control (IAC) Solenoid
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 1995 Ford RV Cutaway, 1995 Ford Pickup, 1995 Ford Econoline, 1995 Ford Cutaway, and 1995 Ford Club Wagon. However, it is still accessible from the selected car via links, so may be relevant.
- Solenoid is by-pass air type. Ensure ignition is off. Disconnect IAC solenoid harness connector. Set DVOM to 200-ohm scale. Measure resistance between IAC solenoid connector terminals. Solenoid has diode. See Fig 1 . Connect DVOM (+) test lead to terminal VPWR and DVOM (-) lead to terminal IAC.
- Resistance should be 6-13 ohms. If resistance is not as specified, replace solenoid. Faults in IAC solenoid or circuit should set a diagnostic trouble code. See QUICK TEST in appropriate TESTS W/CODES - EEC-IV (5.8L) article. If no diagnostic trouble code has been set, see CIRCUIT TEST KE in the appropriate TESTS W/CODES - EEC-IV (5.8L) article for additional testing and specifications.
