2004 Lexus IS300 5 speed, around 144k-145k miles. I was chilling in my car for only like 5 minutes when my Check Engine Light Came on and TRAC started blinking. I scanned the ecu with a reader and came back with these codes. My older 2002 lexus is300 had a evap issue before but it was only giving me a p0440 code. Anyways, what are your guys opinion on what I should do? I was told to replace the EVAP canister vent solenoid. But idk
Start with the easy stuff. I would replace the gas cap with another OEM. Then inspect your vacuum lines under the hood. Blank the codes and do a drive cycle.
^What he said. I've been getting some EVAP codes recently, 441,442 and 446 as well. I replaced the gas cap which had some cracks and splits on the rubber o-ring, I replaced some torn hoses going the VSV under the hood and the codes still came back. My VSV tested bad (no continuity between the pins) so I have one on order. The VSV is what fixed my EVAP codes with my last IS so I'm thinking this is the issue.

The manual has a complete trouble-shooting procedure. I'd probably start there. The whole point of the codes is to point you in the right direction so you don't end up shot-gunning parts at the car in the hope it fixes it.
check your evap lines for cracks, and if access to a smoke machine use that. . i replaced this from the video and a evap piece by the intake to fix mine. ive found that its not always a vsv issue or gas tank issue with these cars.
Well that did it, Evap monitor is completed and their is no pending codes! THANKS
