A vehicle has a secondary air injection system that delivers air to the dual-bed catalytic converter. This vehicle fails an emissions test for CO (Carbon Monoxide) and HC (Hydrocarbons). Engine operation is normal, but the owner complains about excessive fuel consumption. A diagnostic trouble code (DTC) is stored indicating secondary air injection system air flow is always upstream. Technician A says the secondary air injection diverter (AIRD) solenoid plunger may be sticking open. Technician B says the secondary air injection diverter (AIRD) valve may be sticking. Who is right?
◦ Technician A
◦ Technician B
◦ Both technicians
◦ Neither technician
