Air Injection Solenoid Valve

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 F-Super Duty, 1995 Ford Econoline, and 1995 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
  1. Vacuum control valve is normally closed when not energized. Valve may come with or without controlled bleed. Unstable idle may result from a leaking AIR solenoid valve. An electrical malfunction with valve should set a Diagnostic Trouble Code (DTC).
  2. If unstable idle exists, remove vacuum hose from valve and plug hose. Warm engine to normal operating temperature. If idle becomes smoother, replace valve.
