Vacuum Control Solenoid Valve Operation

Fig. 10 Vacuum routing:

1. Disconnect vacuum sensing tubes from solenoid valve and vacuum pipe.
2. Blow through solenoid valve (orange coupler) from vacuum sensing tube located on air filter side of valve. Air should pass through valve and come out port of other side of valve.
3. Disconnect electrical coupler from solenoid valve, then connect battery voltage to terminals on valve.
4. Blow through solenoid valve from vacuum sensing tube located on air filter side of valve. Air should pass through valve and come out through air filter.
