Recurring codes

I am having a recurring code issue on my 2001 Wrangler 4.0L 5-speed.
The code is PO443, which is the "Evap Purge Solenoid Circuit. The only detail I have on it form the service manual states that it is an open or shorted condition detected in the circuit. I have replaced the solenoid, the filter and the Leak Detection Pump, reset the PCM, and still get this code. Does anyone have any ideas on what thenext step should be in the troubleshooting process? Thanks.
