[b]Hi guys and possibly gals!
My 2002 Elantra's check engine light came on a while back and about a month ago I hooked
a code scanner to the OBD II port and 'evap purge control valve incorrect flow' or something like
that came up. It's p0441 anyways. So from what I have been
reading out here is that a common problem with this car would be the purge valve solenoid.
So I bought a new Dorman valve and replaced it. It's the one near the intake manifold. I
reset the light. Next day CEL comes back on! So I bought a canister close valve, the one that
goes in the back next to the vapor canister, as I have read was a second most common problem.
Replaced it, reset the light, next day light comes back on!!
Do you think I should replace the vapor canister or should I take it to a mechanic to smoke test it
and check things I may not know about? It could be a leak but the hoses from what I can see still
look in good shape. I have been taking my time cause I don't have to bring it to inspection here in
Jersey until March. But it's gonna hafta get fixed eventually. Thanks.

I dont own Hyundai car, I drive everybody else Hyundai during day
is seen by the tank pressure sensor as a voltage fluctuation fed back to PCM so PCM know it command of Purge is working down the line as an action.. a leak in the purge line between the purge and canister/tank pressure sensor,, sensor see no change, so you can get MIL..
Purge stuck open and PCM see tank pressure sensor change when there is no command from PCM to purge, we get MIL.
Pretty easy now if you know what you looking for... I deal with it everyday as a Certified Hyundai Tech
