Secondary Air Injection System Relay "A" Circuit Malfunction

The electrical circuit controlling the first secondary air injection relay has a malfunction, such as an open, short, or resistance problem. The relay is responsible for powering the air injection pump and switching valves, so a fault here disables the entire system. The vehicle will have poor emissions control until the relay circuit is repaired.
