There is a prob in your vapor recovery system. I had same issue on my 02 Sienna. In my case and according to my research the most common cause is the VSV valve on the charcoal canister is bad. I replaced mine as a unit (valve and canister). Dealer can diagnose pretty easily.

oh and where is the VSV valve and the charcoal canister located on my 99 es300

i know on my wifes 97 es300 the charcoal canister is in the back near the fuel tank and where you put gas in, i would think that yours would be the same, the VSV should be close also.... also overfilling your gas tank can cause this code to go off as well as damage your charcoal canister. brad
