I think with the ignition key on engine not running lower the tire pressure 10 psi then refill to correct pressure repeat for all tires in less than 5 minutes and the identification of each sensor is reassigned. There is away to relearn the sensors using a scan tool and a way to reset the using the the driver information center and or the trip odometer reset button but specific instructions need to be followed. There is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You can get a one week subrcription or year subscription very cheap. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual. try http://bit.ly/mitchell_repair_manuals_online and get an online repair manual subscription.
