Purge Control Solenoid Valve
Disconnect purge control solenoid valve connector, located next to air inlet. Ensure air flows through solenoid valve vacuum ports "B" and "C". Using fused jumper wires, apply battery voltage to solenoid valve terminals. Apply air pressure to a solenoid valve port "B". Air should flow from port "A". If valve does not operate as specified, replace solenoid valve.
