Dual Air Control Solenoid Valves

WARNING: This page is about a different car, the 1994 Ford Bronco. However, it is still accessible from the selected car via links, so may be relevant.

Function of each valve can be determined by externally energizing valve with vacuum lines attached. Check resistance of each solenoid. Resistance should be 51-108 ohms when checked at coil terminals. If resistance is not 51-108 ohms, solenoid should be replaced.
