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 :confused::confused::confused:

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.

Thanks guys! I’ll start off with the gas cap and look for any bad hoses. Wish me luck !

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.

did that fix it ?
Hey, late reply, But about a month ago i deleted the code and tightened my gas cap and the light came back til now. So upon inspection from the engine bay I noticed that this plug to this evap piece was disconnected. Could this be the reason why Im getting these codes? I dont see any cracks from the vacuum lines. Just need some second thoughts lol
