There is an EVAP check port (green colored cap) close the sensor under the hood - the sensor itself should be right on the airbox. P0446 could be anything from a leaky gas cap to a plugged vacuum tube. Most common culprits are a leaky gasket on the filler cap - if it looks deformed or shredded - I'd replace it. Ouch, definitely watch for topping off of the tank - that is the #1 cause of vapor canister failures on the 8th generation Corolla. Topping off can cause liquid gasoline, instead of just gasoline vapors, to enter the canister. Once liquid gets in there - the activated charcoal will become saturated and you'll end up with a $200-$300 paperweight. Fish i totally give up changed the cas cap and it gave me about 20 mores miles before the CEL came on again, this time a went 140 miles then got the CEL again anyway since i gave up my friend is going to take care of it, hes the head mech at the Lexus dealer here in NY. Hope its simple and fast!!

well i'm going to check all the hoses tonight and check the gas cap, how is a sniffer test performed? i really hate taking this car to the dealer. my local toyota dealer is a retarded crook! i know from experience. well i only have code 0446 now so changing the canister corrected the 0441, does the 0446 narrow anthing down? does anyone know where the sensor in the engine is? i know when i filled up the attendent topped of the gas so much it overflowed i'm hoping that was the cause. i cleared the code and am getting a new gas cap tomorrow.

canister wasn't cracked but since i changed it about a 100 miles ago the check engine light didn't come back on. i'm not really handy so changing the entire canister was alot easier than trouble shooting it. I'm about to scream after getting code 0441,0446 i changed the canister! after 110 miles the check engine light returned i don't know what the hell is going on
