I have been getting a P2238 error code and found that there is a technical service bulletin out on it. I have a 04 Camry with 75k miles, and according to this link, it may be under warranty. I have been getting the code on and off for a few months now.

A quote from the excerpt:
"I can't believe they did not check for this,I can not believe some of the incompetence that exists out there, by the way the warranty period for this is 96mos/80,000 miles so it will be fixed at no charge to you unless it is out of the time/mileage limits which I doubt is the case."
I tried calling the local toyota dealer and they told me that the warranty on this is 3 years or 36k miles. Another dealer didn't even answer the question, saying that they had to "get back to me", and never did. If I can avoid dropping an estimated $350 to $375 to fix this, I'd like to try.
Any suggestions?
