Today the local Chrysler Dealership re-set my wheel sensors using a DRBIII Scanner plugged into the OBDII port. Essentially telling the ECU that four new sensors have been installed and they can be identified with the new codes that the tehnician then inputs. Total time; 20 minutes, no charge.

The technician told me that the new Chrysler Vans have sensors that re-set themselves. Personally I like what I have been reading about the indirect method of sensing pressure. No batteries and no visit to the dealership when new are installed.
