This is a common problem with these vehicles. First, clear the computer. This must be done with a scan tool. See if the code resets. If it does, take it to the dealer. Chrysler is aware of the problem. They issued a TSB (Technical Service Bulletin) in April of 2003the concerning code P0129. HTH. -Jim
