Hi there your code P0418 Secondary Air Injection System Relay "A" Circuit Malfunction

The seconadary air injections system prmotes the warm up of the cataltic converters during start up to start burning the exhaust gases quicker. The check engine light when you start up is P0030 Heated oxygen sensor Heater Control Circuit (Bank 1 Sensor 1).

I suggest that you take you truck to your dealer for proper emmision service
