I have a 2005 Avalon Touring with 42,000 miles. The other day the check engine light came on so I took it to a mechanic. He told me that the "purge cannister valve" is leaking and that it needs to be replaced immediately at a cost of $600.00. Does anyone know anything about this "purge cannister valve"? I find it totally unacceptable that such a problem would occur with a Toyota high end vehicle that is only three years old and still has relatively low miles for a Toyota. Any advice?

Here is some info, taken from About.com on autos:
This system controls flow rate of fuel vapor from the EVAP canister. The opening of the vapor by-pass passage in the EVAP canister purge control solenoid valve changes to control the flow rate. The EVAP canister purge control solenoid valve repeats ON/OFF operation according to the signal sent from the ECM. The opening of the valve varies for optimum engine control. The optimum value stored in the ECM is determined by considering various engine conditions. When the engine is operating, the flow rate of fuel vapor from the EVAP canister is regulated as the air flow changes.
The good news is that this is part of the emission control system on the car and should be covered by Toyota under warranty (my opinion). Call a local Toyota dealer and ask. Hope this helps... Enjoy your Avalon... and post your results for others to see when you get an answer...

The purge cannister valve is part of the emissions system and may be covered by the emissions warranty: Check your owner's manual.
"Federal Emission Coverage: Components under the federal emission defect warranty are covered for 36 months/36,000 miles and specified major emission control components are covered for 8 years/80,000 miles. Specified major emission control components under emission performance warranty are also covered for 8 years/80,000 miles. In addition, emission performance warranty is applicable for 24 months/24,000 miles in states and local jurisdictions that require a periodic EPA-approved inspection and maintenance program.
California Emission Control Coverage: In California and any other state that adopts California emission warranty provisions, performance warranty and defect warranty coverage is applicable for 36 months/50,000 miles, and specific control devices are covered for 7 years/70,000 miles."

I live in Kentucky and we did away with emissions testing last year. Will that have any bearing on warranty coverage? How do I know which one of the warranties you mentioned above fits my situation; I want to make sure I am totally armed when I make my final visit to the dealership. Thanks for your help!

Maybe you removed the gas cap without adding fuel, enough fuel..
Or maybe you left the gas cap loose....
"took it to a mechanic."
Who would more likely than not take advantage of you even if the problem were as simple as above.

Before handing out a lot of money check/have somecheck the vacuum line under the engine air filter. These often come off when someone changes or checks the filter. Have someone else check the computer to see what the problem is. In Ga. Autozone will check it free, others that I know of is O'Reilly's. They will also sell you a part and some times install it for you free, depending on the length of time it takes.

I tried the gas cap thing already and nothing happened. I am going to get a second opinion before I do anything.

Thanks for that bit of information. We don't have an O'Reilly's, but I will take it to AutoZone before I go to the dealership.

If you left the gas cap off or something stuck open in the evap sys the code will be P0455=Evap Sys Gross Leak Detected. If you tightened the gas cap but not tight enough the code will be any of the following: P0455; P0442=Evap Small Leak or P0456=Evap Very Small Leak. Depending on the condition of the purge valve, you may have the same codes above so, it is not only the purge valve that can cause the above codes. Any problems on the Evap sys may give you these codes.
