Throttle Body and Trottle Position Sensor

I have really enjoyed having the Quest. After shopping around I still believe we made the best choice over all the rest. Ours has about 120,000 miles on it and now we have run into some sensor issues. After replacing both camshaft sensors we solved the original problem that we started with but caused another. It has to do with the throttle position sensor according to a scanner. I called two different dealers to inquire on cost and location and was told by both that I would have to replace the whole throttle body. If that will correct my problem I don't mind doing that, but I have heard there is a re-learn process for other vehicles. Would some one know if there is anything like that for the Quest? And one more thing is there a service manuel for the Quest like from Chilton or Haynes. I can't seem to find one. Thanks for the help with this.
