For anyone that is needing TPMS for their Prius, I have a smoking deal right now, a set of 4 OEM TPMS for $85 shipped. This will fix the TPMS light that's constantly on because of bad/old sensors. You'll need to reuse your air cap, I don't have the cap. Toyota (42607-06030)
I work in South El Monte, 9 to 5 M-F. You can come at your convenience if you want it. About 2 miles from Longo Toyota
If you have more than one set I could use some. I'm starting to get the TPMS light when it gets below freezing, so I think they're on the way out!
