Just some stuff I found searching the gool 'ol internet....
"A loose or missing gas cap on a late-model Toyota often leads to a trouble-code hat trick of P0440, P0441 and P0446. Don't get carried away here because installing or tightening the gas cap usually takes care of all three codes."
"P0441
EVAP Emission Control System Improper Purge Flow"
Def tightened the gas cap and removed the + from the battery and let it sit for an hour to reset the ecu and clear the light, after an hour or two of driving the light came back on. I did this twice, making sure all my vac hoses were in place on the intake the second time. Any ideas???

Hey man,
There was a thread a little while ago that included all of the Lexus Tech's we have as members here. If you search for it you could PM one of them and they might know or else check their manuals when they get to work tomorrow.
