2003 Dodge Caravan Camshaft Sensor 03 GC-SE 3.3L

The wife's GC died today right when she got to work. After cooling off it started right up. I met her after work to follow her home and it died again. Again, after cooling off it started right up. We pulled into an Advance Auto Parts, and they checked the code, don't remember the # but it was for the camshaft position sensor. I now have a shiny new one, but I can't find the old one! Where in blue blazes is the thing located on the engine, and how do I go about replacing it? The %^$&# Haynes Manual just tells me what it does, not where it is or how to replace it.

As a visual person, a pic or diagram would be very welcome!
