Re: p0410 secondary air injection system malfunction solution?
Just put 2+2 together and noticed that you are having problems with the Air Pump and/or the RCM.
I've noticed that a few of the RCMs that I have received for repair (mine included) have burnt contacts on the relay that controls the air pump. Cleaned my contacts after receiving the PO410 and haven't had the problem since.
My 2 cents.
