My car (2006 Ford Expedition) has tyrw pressure sensors. How do these transmit from the wheel and how are they powered?

Each of your car's main wheels has a small pressure sensor installed inside the rim, which transmits a signal to a central receiver in the car. They are powered by batteries, which typically last for 3-4 years before they need to be replaced.

Your car probably uses pressure sensors manufactured by Schrader Electronics in Northern Ireland.
This system uses a small battery-power pressure sensor with radio transmitter on the back of each tyre valve, attached to the wheel rim. The batteries are designed to last 10 years. There will be a corresponding radio receiver next to each wheel, which picks up the signal from the sensor and passes it to the system's ECU.

and http://www.schraderelectronics.com/index.cfm?location_id=1044
There is an alternative system that uses the ABS sensors to sense the speed of each wheel, and therefore determine if the diameter of one tyre is reduced, and warn the driver that the pressure may be low on that tyre. These systems are cheaper and more robust (no additional components inside the wheel, no batteries), but less accurate.

On our car, the sensors were quite accurate. When I did have to add air to a tire, it seems like I also had to push a red reset button in the fuse panel. This was on a 2000 Buick Regal....

they measure ur tire pressure a 5 vt signal is sent to each sensor from ur cars computer and signal is sent back to computer witch then sends reading to dash

They sence the tyre pressures.
Do you really want to know?
