Order of inspection
P0416 Secondary Air Injection System Switching Valve B Circuit Open Low
The P0416 code means the circuit of secondary air switching valve B is open, so the component gets no current when it is activated. Check the connector, the fuse and the wiring before you replace the valve. It does not affect driving, but it keeps the vehicle from passing an emissions inspection.
