I have a 2009 Chrysler town& country, 4.0. The van ran like crud today. lightning bolt, shutting off on the interstate but getting it home. I pulled a code from the dash, P0339, Crankshaft position sensor. If its not one thing,its another with this unit. My question is about the cost. Has this happened to anyone out there and if so how much is this going to set me back. Under 40 mph it runs great but still has other issues, it starts when it wants to or you get (1) one click and your at its mercy. I sure could use some encouragement. Thanks for listening.
