Code p0412, im clueless, PLEASE HELP!!! A month and a half ago I installed LT's and a catted Y pipe. I still have the AIR system, and did the air restrictor mod. I just recently threw code p0412 only(Secondary AIR injection system valve A malfunction). Is this the code for a bad check valve? If not, what is solution without removing the AIR system? I need to keep it. Thanks....
