Secondary Air Injection System Switching Valve B Circuit Open

The electrical circuit to the second secondary air injection switching valve is open or disconnected, cutting off the signal needed to operate the valve. Without this connection, the valve cannot function, reducing the system's ability to control emissions. The vehicle should be inspected and repaired to restore emissions control.
