not sure if this helps, see if the gas cap is bad.
The dreaded P0441 code
This is my first post on this forum. I'm posting because I read previous posts here and believe that the experts here know the most about this problem.
The code is being set on my grandsons 2001 Celica GTS. Also, whenever he gets gas the engine either will not start without depressing the accelerator pedal, or will start but runs rough, or starts okay but shuts off soon thereafter. All of these symptoms go away after a few minutes.
I've done various tests by referring to my Celica manual, and the official Celica wiring diagram manual. I won't go into details about the tests now though because I found one problem that could be the one causing the code.
On his car the blue headed connector is connected to the VSV for EVAP. From reading prior posts here, and referring to the Celica wiring diagram, this is wrong. The black connector should be connected to the VSV for EVAP. But, when I disconnected the blue, and connected the black, the ABS light started flashing. I don't know what this means. So, before I permanently switch the connectors, I'm trying to find out if someone else has had this occur, and what they did.

What is the history of the car prior to the codes being set?
Is it stock or modified?
What other repairs have been attempted?
As mentioned above, try replacing the gas cap and clearing the codes.
As for the rest of the symptoms, unless the Evap purge is being enacted when the motor cannot manage the extra fuel stored in the charcoal canister under the car (hot start, idle, etc.), or it is stuck open all the time then I suspect they may not be related to the P0441.
Hope this helps. Happy New Year.

I think it's fixed. Did more internet research last night and learned that a flashing ABS light means that the ABS system isn't working, but the brakes still work. So, I decided to go ahead and switch the wire connectors, removing the blue and connecting the black to the VSV(EVAP) solenoid. Cranked the car, and there were no warning lights! Drove around the block and still no warning lights. So, maybe this is resolved. Won't know for sure though until the next refueling.
Update, 1/7/14: It's fixed. No problem during refueling now. Done deal!

The Blue connector definitely does not connect to the EVAP VSV.
the blue connector goes to the butterfly valve in the stock air box. the black connector is for the EVAP purge VSV.
there is no fuel in the charcoal cannister. only vapors. where did you come up with that?As for the rest of the symptoms, unless the Evap purge is being enacted when the motor cannot manage the extra fuel stored in the charcoal canister under the car (hot start, idle, etc.), or it is stuck open all the time then I suspect they may not be related to the P0441.
If that's all that's caused mine you will surely be my heroes because now i don't have to drop the tank. Blue was on vsv and black was on the box, lets see if the light stays off.
Had forgot about this post; but, just for the record, my grandson's GTS still works like it should. As for how the wires got switched in the first place, I think I inadvertently switched them when doing some other work on the car. Subsequently I attached a tag to mark the blue cap as "Unused" to avoid this mistake in the future.

This is the same issue I had when I first bought my car from the dealer. They replaced the charcoal canister, fuel cap, etc. and it was this simple thing that was throwing the code the entire time. Still get it from time to time but it might be time for a new cat. Passed emissions just last month so I'm not sureIf that's all that's caused mine you will surely be my heroes because now i don't have to drop the tank.

are you getting a P0440 also?
the blue plug has nothing to do with the ABS system.
look into the switching valve back on the charcoal canister under the gas tank
