Got the ever so popular PO411 code and need some help diagnosing. I have not been able to find any leaks that I know of, when I start the car I hear the whine for about 70 seconds, so to me that means the sec. air pump is working right?



I need to mention on Sunday 4/8 I got in an accident where a lady rear ended me at 30mph a day later my light came on.
