The code relates to the air pump itself that is located on the passenger front of the engine. It is a round black thing that has vacuum lines and electrical lines coming off of it. It also has a small diameter metal tube running from it to the center of the exhaust manifold.

I would start by tracing the vacuum lines and the electrical lines. Make sure all are intact and connected properly. I'm thinking you have a loose vacuum line.

Good hunting and let us know what you find. :)
