P0412 SAI System Switching Valve A Circuit Malfunction


now i just need to figure out were or what it is?

thanks

The SAI has a vacuum actuated valve to turn it on and off. This is controlled by an electric solenoid valve. It would have to be the electric one that is malfunctioning. Both are attached to the surge tank on the drivers side.
