Combination Air Injection By-Pass (AIRB) & Air Injection

WARNING: This page is about a different car, the 1995 Ford RV Cutaway, 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.

Diverter (AIRD) Valve

Combination AIRB/AIRD valve combines the functions of the AIRB valve and the AIRD valve into a single unit. Valve is located in air supply line between air pump and upstream/downstream air supply check valves. The AIRB portion of the valve controls flow of secondary air to the exhaust system or allows secondary air to be by-passed to atmosphere. When air is not being by-passed, the AIRD portion of the valve switches the air injection point to either upstream or downstream location.
