Air Injection Control Valve Solenoid

Remove vacuum lines and electrical connector from solenoid. Remove solenoid from vehicle. Connect hand-held vacuum pump to middle vacuum port "B" of solenoid. Apply battery voltage to solenoid. See Fig 1 . Ensure correct polarity is used or damage to solenoid may result. Apply vacuum. As battery voltage is applied and removed from solenoid, vacuum should alternately bleed from remaining 2 ports.
