i6LeXo300 - look on the driver's side of the engine bay towards the firewall. there will be a tube that comes up from under the car and connects to something else going on top of the engine. this tube for my car was disconnected and apparently the pressure from the gas tank can blow this tube off due to an old hose clamp. if it's disconnected, connect it and see if your CEL goes away.

4play4dr - look for an open hose around your engine bay bud. i was getting the p0446 code intermittently but more often the p0441 code. after connecting the exhaust evap hose (or whatever it's called) i should be ok now.

good luck guys!

Ok guys- took some pics for you that have a gs300.

Here's your engine standing by the driver's side headlight.


Zoomed up on the red area from the pic above.


Highlighted the tube that came loose in red. This tube triggered my P0441 and P0446 codes. Once it was connected, no codes and a trip to the dealer saved!


Thanks Kaiser!

Can anybody pin point this hose on a 400 V8?

i need help bad..Im about to bite the bullet and buy a brand new canister but scared that it might be a loose hose or something like that!!

before you do that have someone check and make sure you don't have a leak if you don't wanna check yourself sir....then buy the canister if you have checked the gas cap and its good also

just bring it to a smog and repair station and save yourself the money if its just a leak for so... have them run a smoke machine on your entire system and check if your purge valve is workin as well.... easy as that.. thats what i would do but i have school supply at the local college where i can use all their tool..Big + for me
