Hi, my 2007 3.3L DGC CIL is on, scanner displays P0441. I already replaced the gas cap. I disconnected the solenoid purge valve tubes (by the rad cap), and connected the lower tube to my smoker. The only place that I see smoke escaping is from a cylindrical shaped housing that the power steering reservoir tube is also clipped to. The top of this cylinder has oblong openings which appears to be a vented top. This is located under the abs pump, and pic is attached. Any suggestions would be appreciated to properly smoke test this system to find the issue. Thanks.
