OK, jbeurotech, you've made your point about testing prior to replacing. But, help me to understand how a hole in the breather line and/or loss of vacuum somehow in the breather line is going to cause a "PO444 - Purge Valve Circuit Open" fault code? An open circuit usually means a break in the continuity of the power/control wiring.

Have you come across situations when the PO444 fault code was caused by the loss of vacuum in the breather line?
