I have been battling my secondary air system for a while now. The pump sounded like it was dying, and now I keep getting either P1412 & P1415 or P1414 & P1417 codes. I am guessing that the pump is, indeed, dead and I just need to replace the bugger for $230. Is there anything else that I might be facing other than the pump. When I started it up this morning for the first time I had the bonnet up and there was no apparent sound from the pump and when I felt it with my hand there wasn't much, if any, apparent movement.

Thanks,
