" Well, i been fighting with my check engine light cause P0441 EVAP Purge Valve , but today i found solution, how to fix it.
At first, u need to check resistance with digital multimeter. Usually should show about 22 - 30 ohms.
Then check harness. Should show between 13-16 Volt (set your multimeter for DC measuring).
If numbers match with those posted, Looks like like your EVAP Valve is just JAM !!!
So what i did was really easy
Remove EVAP Valve and spray inlet with WD40. Then bring 12V in to it. You should hear and feel clicks. Change polarization of power supply and spray WD40 again.
After that, put all back together and start engine. If you not hear and feel clicking, just knock on valve
My start working on third whack "
Czyli wyjac, napryskac wd40, potem "na krotko" pod 12V, napryskac i zamieniajac + z - pod 12V.. powinien zaczac klikac. Zaloz spowrotem, skasuj bledy i pojezdzij, moze pomoc zwlaszcza ze masz opornosc 25ohm czyli miescisz sie w prawidlowej normie.
