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

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