I assume you are referring to code 340? Cam sensor CKT malfunction?
How often do you get the code? How is the engine idling hot and cold? How does it feel at cruise and under acceleration?
I just fixed mine, but I have to give it some more time to be sure. As you know by now it is not the actual sensor giving you problems.
I was planning to post my results as soon as I am comfortable that it is finally gone.
Let me know your symptoms.
