I don't know which one you want fom ebay, BUT...most "universal" TPMS sensors need to be programmed in order to work for a specific make - model- year range of car.

Buy a sensor from a Toyota dealer for a Gen2, and you can copy down the ID number (to write it to the car's ecu via TechStream), then install the sensor on the wheel. Good to go.

A universal sensor needs to be "told" what frequency it works on, and that you're putting it on a Gen2 Prius. Also need to decide if the programmer tool should generate a random ID, or if you are "cloning" the existing ID. Also the tool can "ping" the sensor to confirm it works, and check status on the other sensors.

Cheap can work, but it ain't always the least expensive route in the long run.

FYI, as mentioned, TPMS batteries are effectively sealed in the sensor- dead battery = new sensor. TPMS "service" usually denotes removing the sensor and replacing the valve stem (if separate) and seals. Metal stem design like on Toyotas cause lots of corrosion leaks in the salt belt and are a pain to deal with.

Also, if you need to change the TPMS ID's with TechStream, I don't recall if you can just do one sensor, or if you have to rewrite all four at the same time. So you might want to record all the current ID's before doing anything.

Not buying a universal TPMS, but one that's identical to standard one used in Toyota...
