All

My check engine light came on yesterday while driving to work. The car itself ran fine with no changes in behavior.

The code read P0410 Secondary Air Injection System Malfunction

Is there a common problem with the air pump? The only time I have seen this code on the forum is when I reported it back in 2004. The issue there was a blocked cat which caused poor performance.

This is not the issue in this case.
