Switching Solenoid Valve
- Disconnect vacuum sensing tubes from switching solenoid valve and vacuum pipe. Blow through switching valve from vacuum sensing tube "B" in Figure. Air should pass through valve and escape from front port.
- Disconnect electrical connector from switching valve and connect battery power to terminals on valve. Blow through hose again; air should pass through valve and escape through filter at rear of valve. If switching valve does not respond as described, replace switching solenoid valve.
