p0412 code, secondary air valve malfunction, help hey im really hoping someone can help me because this SES light is driving me crazy. originally i had code p0410 and p0412 on. i decided to take the pump out take it apart and see if maybe the motor was stuck. it looked out and after puting it all back together the pump starts with the car and now i only have error code p0412. i really dont know what this could be. the air fuse is fine, the relay looks fine, i even switched it with the one from the A/C compressor becuase they are the same and theres no difference. could it be a bad check valve or is there something im missing? all the tubes look fine and all the connections are tight. thanks i really appreciate the help

I had an intermittant PO410 code and I replaced both air valves and the 3way valve that connects the air tubes at the back of the engine. I haven't thrown a code yet (fingers crossed)
