Have a 2003 hyundai elantra gls has code po441 I've replaced the o2 sensor twice and some bad fuel lines the purge valve and canister have been replaced to but still saying po441
This was never an oxygen sensor issue. There are connections that go from the PCM computer to the purge control and those need to be checked. Check all the hoses again to be sure,
