air injector schematic


Recommended Posts

I'm having problems with the air injection system also. There is a rough schematic on the inside of the engine compartment lid.

Now I have a question I'm hoping someone can help with. I got an alarm code some weeks ago for the secondary air injection system. The garage checked out the air pump and determined it was bad. It was drawing way to much amperage and overheating. The alarm persisted. They cleaned out the inlet manifold spiders, the alarm still persists. What other things are the logical next steps here? Any advice is appreciated.

Check the small vacuum hoses that connect to the diverter valves.

I had the same problem about a year ago. Replacing the DVs fixed the problem. Inspecting the original DVs revealed a small hole in the rubber diaphragm. This must have caused the leak in the secondary air injection system and triggered the CEL. FWIW, I went with Bailey DVs, as they are maintenance free.
