Does anyone know of a chip that measures the tire(s) pressure in the engine? We have a 2008 Roadster and conncected to the engine to fine out hy the idot light comes on then off all the time. The chrysler boys says it is a bad computer chip and needs replaced. We forgot to get the part number. Cost is $750. Would like to know if anyone has ever to replace this part of had the same concern?

Thanks for your time.
