Po443 Emission code - need help

Have a 99 Jeep Grand with 125,000 miles, getting a P0443 code, replaced the purge valve, checked for leaks all looks good. Reset the code at auto zone and it came back on by the time I got back home. It had a P0441 code also but that hasn't come back yet after about 4 decent trips. Any suggestions on where hunt to figure this one out?

well I guess from the description it's electrical, not plugged line or charcoal canister. Guess I'll need a scan tool to go further. There are 2 wires to the solenoid, one power and one from the ECM, both appear to have continuity with the ECM ad 5.xx volts, and the power at battery voltage while running. Don't know if there are any other devices or wires in the circuit as I don't have a wiring diagrahm. Anybody have access to a wiring diagrahm for this circuit?
