I have a P0441 code. I tried couple spare gas caps that I have as spares. The code is still here.

I understand an alternative to the Bosch valve (0280142300) is the genuine Hyundai valve (28910-22040) from reading past threads in the forum, for example:

Please see the Bosch versus the Hydundai, right and left respectively in the pic. I ordered the Hyundai one as it was easier and quicker to source from Amazon Canada. Their body sizes appear different. Does someone recall if the Hyundai ones look exactly the same, or a little different as shown in the pic? Thanks!

 

I got the hyundai one, and it looked like that and was fine. It did not fix my P0441 code, although it does appear less often when I scan the codes.

 

@evil_goat Check you vacuum lines the SAI ones in particular, get cracks and can cause that code randomly

 

I'm an OEM Hyundai Purge Control Valve guy, replace em once and so far haven't touched em since.
