Car: 1996 Jetta GLX VR6
Just wanted to confirm operation of a Secondary Air Solenoid 191 906 283 A.
No voltage or disconnected = closed no vacuum applied to the combi
12 volts applied = open drawing vacuum to the combi
Has anyone ever seen one stuck open applying vacuum continuously?
Also to test the pump, does it just require battery and ground? I applied battery and ground to the pump and nothing! Having replaced the Combi valve 18 months ago and now having a possible bad pump and solenoid is not going over real well......$$$$$.
Any recommendations? All i want to do is get 6 readiness codes cleared for the PA inspection. I'm not interested in a chip because of the advance and having to burn high octane fuel.
