Secondary air system, checking: Function: Notes
- After cold start, engine control module -6- activates secondary air pump -1- via secondary Air Injection (AIR) pump relay -5-, and air is fed to secondary air combination valve -3-.
- At the same time the system activates secondary Air Injection (AIR) solenoid valve - 8- which supplies vacuum to secondary air combination valve -3-. The relevant combination valve opens a passage for the secondary air system to supply air to exhaust ports in cylinder head.
