My 2001 Accent 1.5l is giving me an engine code of P0441. After reading several previous posts I have come to the assumption that it must be a bad purge control valve. One fo the other indicators besides the code is after I fuel up the engine runs really rough and even have to give it gas to keep it from stalling in most cases. My question is 1) does this sound like the Purge control valve and 2) is the Purge control valve the same as the purge control solenoid valve?

Thanks

if it is just a bad pcv valve you are looking at $10 and 5 minutes of labour, good idea to either clean it or just swap it out every year.

The PCV(Positive Crankcase Ventilation) is not bad, rather the Purge Control Valve....thanks for the response though.

The "Purge Control Solenoid Valve" is the "Purge Control Valve".

Rough idle is a typical symptom of something amiss with the purge control portion of the evaporative emissions system. It could be the valve itself is not operating correctly, the evap canister (vapor canister) may be leaking, or full of raw gas instead of vapor, or maybe even the purge control valve is getting a faulty signal from the ECU.

The soleniod is checked by applying a voltage to it and checking to see if it closes, or opens (I'm not sure if its un-energized state is normally open, or normally closed). If the valve is bad it is a no-brainer to replace.

The vapor canister can be removed and checked to see if it is full of raw gas (not supposed to be), but checking it for leaks is a bit involved, and probably requires equipmet not normally owned by a home mechanic. Vapor canister failure on cars with a lot of miles is common. Replacement is the fix.

Of course if the ECU is not sending a purge signal to the valve correctly, figuring out why may proove difficult, and possibilities could even include a faulty ECU. I expect this is unlikely though.

I replaced the Purge Control Valve - $23.00 part(finally a part that doesnt break the bank!). The engine light remained ON for the rest of the day although when I started the car this morning it went OFF! I am so excited! That darn light has been on for 3 years now.....anyways, thanks for the help.

Default Hyundai Accent 2001 P0441

Regarding the Auto zone OBD P0441 I replaced fuel cap, PCV valve, purge valve and vapor canister. I still have the check engine light on and same code.
Is anybody knows what sensor sends signal to activate the P0441? Is it fuel tank pressure sensor? If yes, is it possible to simulate pressure or short contact?
