Guys, I recieved the p0441 code and i replaced the purge valve located beside the frame rail, with the genuine nissan replacment. the cel went off for like 2 days, but then came back on, with the same code, and a another code, which i forget, but says system leak. Upon further investigation, i stumbled upon a EVAP valve that is located under the hood, mounted to the intake manifold. I have attached a link to the diagram, it is part number :14920+B. do you think that this could be causing the code to come back, i have taken the replacement purge valve off and it functions properly. I have no other ideas on what it could be. any help is greatly appreciated.
