CEL P0441 code

Danny, here's a simple version.
Fuel expands in the gas tank, for emission's sake, we don't want the fumes.
They move to the evap canister in front of W/W tank (small tube from filler neck to evap can)
When you give it gas, the purge valve releases the vapor(mixed with air) into intake (another small tube to intake) to be burned @ 14:1 ratio.
The ECU controls this.
My guess is when it was hot out, you kept stop/go, it pissed off the system. a second guess is you didn't have a full tank (shouldn't need to)
I'd inspect (you're no stranger to your lines) the lines to gas tank filler neck & vacuum to intake, might not happen again.
luck,greg

Adding to what Greg said, could have been "vapor lock" in the purge valve.
There is alot of heat under there and sitting in traffic like that and with the engine getting to hot (separate issues) it very well could have been vapor lock in the purge valve.
I dont know how old you are and if you are familiar with the vapor lock phenomena that was common on mechanical fuel pump engines.
It was not fun when it happened to you I can tell you that.

Please forgive my impetuance, (I think that's spelded rite) but if I'm not mistaken, on a bypass regulated EFI system, we shouldn't vapor lock
But I was wrong once b/4
Or maybe a senior moment
When you give it gas, should have read, anytime the throttle body opens (i.e. accelerating or cruising)
LOL

No fuel injection with electric fuel pumps do not vapor lock.
My point I was trying to make although not very well said was that maybe his purge valve "vapor locked" thus setting off the code.
I did not mean the engine vapor locked, but his purge valve.
I dont know if it is possible, but space travel is so why not?
