i have a 2000 es 300 with 133k, i went to toyota , paid $85 and they said i need to replace the charcoal cannister. i bought the part and had it installed by a local mechanic to save a few $. about 300 miles the lights came back. i went to autozone and the code is now P0440. I need your thoughts on whats the next step. Thanks Cam
