P0412 - Secondary Air Injection System (AIR) circuit malfunction The PCM attempts to control when air is injected in the exhaust. The DTC indicates a Secondary Air injection system AIR circuit fault.
  • AIR circuit open
  • AIR bypass solenoid fault
  • Damaged PCM
  • AIR circuit short to power
  • Solid state relay fault
  • Damaged AIR pump
The AIR circuit is normally held high through the AIR bypass solenoid and SSR when the output driver is off. Therefore, a low AIR circuit indicates a driver is always on and a high circuit indicates an open in the PCM.

If you need the others like this I can do that for you too. Let me know.
