All,

looking for some guidance on what to look for next to solve my P0441 code on a 04 D2. The code first appeared a month or so ago when I got to about 1/4 tank.

Replaced the purge valve with a Hyundai unit and all was well for amount a month. Around 1/4 tank this week I get a pending P0441 code. Not sure if there is a connection between the code being thrown when I reach 1/4 tank. Any idea what could be causing the P0441 code if a new purge valve was recently fitted?

thanks
Carlo

Bad purge valve out the Hyundai box?
Make sure to clamp the hoses
I got a Bosch part #28910-22040 when I got a P1044 fault code.


You can also try spraying wd40 in the old purge valve to clean it out then add 9VDC battery power to it to feel it clicking opening and closing.

Update - drove the truck around for a week with the code pending waiting for it to materialize into a SEL, but it never did. The code is no longer pending. Truck seems to have worked itself out.
