If it wasn't holding air it would trigger the dash light once psi is below the acceptable range for the tpms. There shouldn't be any need for programming of a new sensor.....It should automatically sync up to the cars computer after driving it like I said. Even if the dealer thought your jeep was an 07, I believe they still used the same frequency that year. The sensor is either bad, or the wrong frequency. Thats the only 2 logical things I can think of.
That's true , but the replacement is in the spare. . The dealership may have to "wake up " the sensor, if they were even right in replacing it in the first place . I would take it back , in fact they would have seen my P.O'd butt again as soon as that light came back on.
here's the info from the service manual
The battery operated tire pressure sensors lay dormant (Park Mode), then wake and start transmitting (Drive Mode)
when the vehicle first reaches speeds over 20 mph (32 km/h). Once the wheels stop rotating for a period of approximately
20 minutes, the sensors shut down until again awaken. Although not transmitting as when in Drive Mode,
while in Park Mode, the sensors still transmit approximately once every 13 hours to let the receiver know air pressure
status at that time.
Using an RF signal, each sensor transmits tire pressure data approximately once every minute. Each sensorís
(transmitter) broadcast is uniquely coded so that the wireless control module (WCM) can monitor the state of each
of the sensors on the four rotating road wheels. The WCM automatically learns and stores the sensorís ID while
driving after a sensor has been replaced. There is no formal retraining procedure necessary.
