If it's a factory style TPMS sensor, you'll need a new TPMS sensor. This means that the wheel will need to be removed, the tire unseated from the wheel to replace the valve, the tire should be re-balanced after the tire is re-seated and inflated, then the sensor will need to be "woke up" if it's in sleep mode and the sensors can then be initialized, which requires an activation tool and capable scan tool.
If by chance the sensor has been replaced with a Dorman TPMS sensor, then you can get just the valve assy. to replace the broken valve and not have to wake up or initialize the sensor, but you will still have to break down the wheel to remove the sensor and replace the valve.
