2002 Dodge Intrepid fault code P0846

My 2002 dodge intrepid,2.7 liter V6 started missing, heating up and generally quit. The fault code was po700 and po846. Where is the cam position sensor located and is this something a DIY'r can do? Thanks
I don't know where your getting the cam sensor idea from but those codes are transmission specific codes and you just need to get it to trans specialist for that.
