EVAP Canister Purge Solenoid

Disconnect vacuum and electrical connections from solenoid. Apply low air pressure to upper port on solenoid and ensure air pressure does not flow through solenoid. Using jumper wire, connect negative terminal to ground and apply 12 volts to positive terminal. Apply low air pressure to port "A", and ensure air pressure is released through lower port. Replace solenoid if it does not function as specified.
