I have a 2005 Nissan Murano and can't get rid of P0441. My car's engine and transmission are in good shape. Can a leaking VIAS sensor cause P0441? My latest discovery in a smoke machine test is the vapors are leaking through the VIAS sensor, and that's the only leak I could find after three smoke machine tests. There is no other leak. The purge valve, muffler, catalyst converters, vapor canister purge valve, and fuel cap have been replaced. I will appreciate any help, please?
