OEM Tire Pressure Sensor (TPMS) Part #

Dealership parts dept can be very knowledgable, not last resort lol.

 

Is the OP looking at a dealer's parts site? Part numbers can and do change slightly. This is from McGeorge Toyota:

Tire Pressure Monitoring System Sensor - Toyota (42607-33012)

• 
  • List Price:$91.34
  • You Save:$29.36 (32.10% off)
  • Sale Price:$61.98
  7 In Stock
  
  This part fits your 2010 Toyota Prius

~~~~~~~~~~~~~~

Once you get the sensor, and it's installed, you do realize its ID must be registered into the car's "computer," right? The ID is printed on the sensor.

 

Off subject...

This has reminded me that a while ago I've seen a write up somewhere on replacing the battery inside the TPMS, to reuse them again...

For our 2015 Prius Four I bought Denso 550-0103 TPMS sensors

Amazon Item# B00NQ05U24

which sell for $37.61 each.

These were what I found by cross-referencing the Toyota part No.

Our local tire store (part of a Mid-West regional chain) had no problem pairing these to our car -- neither originally nor at the subsequent seasonal wheel/tire changeovers.
