Just what I suspected. The part can be had from Napa, but they might have to order it which depending on the time of day when you order it you may get it the same day. This is very easy to change and takes only about five minutes. Do yourself will save about $200. You will need a torx screw driver. You would also have to drive it home or tow it. When these go bad you may only drive a mile before the engine dies and you have to wait sometimes 20 minutes before it will restart. You may want to ask the dealer how much they are charging for the sensor and then ask why they are charging $200 for a five minute fix. I have done this before and know exactly how long it takes. You can see this sensor at the back of the engine around the top of the bell housing area. There is one torx screw holding it in and a plug you disconnect.
