TPMS problem after swapping wheels

You just need to "program" the new TPMS into your car. You would need a knowledgeable shop to be able to do this. Or you can buy a MiniVci cable with techstream and do it yourself

 

The problem is knowing the registration numbers for each sensor - they are generally on the TPMS sensor (inside the rim) and can be read when installed, or using TechStream from the car after they have been registered with the TPMS ECU.

A dealer might have a separate tool that can scan an installed TPMS sensor externally to pull the number - anyone know anything about that?

 

Any decent tire shop should have a tool to read the TPMS sensors right through the tire sidewall, and program them in through the OBDII port. When I put winter tires on separate wheels (mail order from Tire Rack) on another car, the local Les Schwab would do the reprogramming for $20, but 'couldn't' do my somewhat new car then because their tool catalog had not yet caught up to that model year. So had to go to the car seller for $70. I've since acquired my own tools (separate programmer and RF reader units), though the cost will be very hard to justify for households with just one TPMS vehicle.

I acquired new tires / second rim set for my Prius over the summer, but didn't install until a few weeks ago. One sensor would not read on my tools, so the tire seller (Discount Tire) did the reprogramming for free. It is built into their normal l price, I just didn't put the tires on the car until a few months after the tires were purchased and mounted on rims.
