Please, advise if anyone know how to check if 6 port induction is working, and if solenoid vave 6PI is functioning? Voltage reading on 6PI solenoid terminal at idle was 14.25v

When should there be enough vacuum to operate 6PI Actuator, any way to route vacuum to operate 6PI other than going through 6PI solenoid valve?

Thanks

 

The aux ports are activated by air or exhaust pressure (depending on series) not vacuum.

You may wish to use the search function found in the upper right hand corner of the page for testing and cleaning aux ports.
