TPMS question.

Does your Prime have a TPMS reset button under your dash near the brake pedal like my wagon ? Take a flashlight & look, here's a picture of it.


Here's a video of TPMS reset using the menu on your dash for newer models:

 

Were the tire pressures on the 17's significantly lower than the 15's. I suspect not, and barring that, I'd speculated one or more of the sensors got damaged in the transfer. Also, If they did transfer the sensors over, there would be no need to reinitialize them, that's only required with replacement sensors.

Oh btw: you did check tire pressures were ok??

 

Another member mentioned something like this.
I don't know if it is possible to set the low alarm so high you are setting off the alarm.
So if you hit RESET you should reset alarm levels. On my car, 26.5 psia seems to be the default alarm setting, but you might be able to set it higher.

In order to understand what is going on, you would need to read the pressures using a device such as Techsteam with mni VCI. Then you could see what the pressure/temp readings are. Conceivably the new rim needs a different TPMS, although they seem hard to damage.

 

This happened to me when I took out my sensors when I powered coated my wheels.. so you have to set them all low PSI keep the car on for 5 minutes for the car to register the psi. Then put the correct air amount in tires. Then turn on the car leave it on for 5 minutes and it’ll read the new psi again. It might take longer but it will go away

 

Maybe it just takes a bit longer?


It'd be nice if the manual gave some sorta idea, how long it takes.

 

The later sentence is false. They read the codes through the tire sidewall with an RF reader device. They can do it in the parking lot, no need to take the tires off the car at all. Any modern tire shop has the RF reader / programmer to do this. Probably for free, if they did the previous tire work for you.

And to repeat several other replies, this is completely unnecessary if the same TPMS sensors are still being used. That car already knows those IDs.

If a sensor is damaged and needs replacement, then they must dismount the tire from the wheel rim. But that RF reader device would be used first to determine which unit(s) is not responding, they don't need to remove all the wheels.

For simple resetting, this is absurd. A few years ago, my Subaru dealer wanted $70 to reprogram a new sensor set to the car, the closest tire shop wanted $20. With two TPMS cars in the household, and twice yearly tire swaps for winter, I now am equipped to do it myself.

If that price includes replacing a bad sensor, it is more reasonable, but a tire shop will still probably be better.

 

Again, if no sensors have been replaced, there should not even be a need to read sensor id's, the car should know about them already. Assuming this is true:

Nothing has changed with the sensors. You went into a tire shop, they took the sensors (that the car knows about, and they were functional) out of one rim, transferred them to another. There should be no problem. Unless:

1. Tire pressures are now significantly lower (You have checked? If this turns out to be an actual low pressure, we can all ROTFL.).
2. They damaged a sensor.
3. They replaced one or more sensors.

 

TPMS an area where you want to take your time, because some shops are cheap and some are expensive. Helps to be able to use SCAN Gauge and Techstream to read out your info to debug what is happening.

I had hoped the video above applied to newer model Prii as far as reset. I got the first TPMS year (2006) and dang it 3 of 4 TPMS are still working will be 12 years in July.

 

Interplay with the other three should not matter. The car just needs to be able to read the new one, and have it registered to the ECU. It was the tire shop's error for not having done that reprogramming, or even in using a type of TPMS that can't be recognized by your Toyota.

I would have started with the tire shop to fix this in the first place.

At least they took responsibility, good for that step.

 

Alls well that ends well.
It is odd that the tire place did not know how to enter the codes and get the system back up and running. I like the OEM but one would think they knew how to match with a compatible clone. But my tire place did like it when I bought my own OEM off Amazon for them.

 

I only wish we had Discount Tire here...

 

That is odd. Not only has Discount Tire provided (sold) new working sensors for my second wheel set, and correctly programmed them to my Gen3 Prius, they even came out to the parking lot and re-did the programming, for free, a year later when I temporarily lost a set of sensor codes. (Had I looked through my computer files a few minutes longer, I'd have found them and avoided the shop visit.)

My the car was several years old at that time, allowing plenty of time for their programmers to be updated. Les Schwab ran into the same 'too new' issue when my Subaru was only a few months old.[/quote]

 

I also use Discount Tire, and generally like them. But one of their young employees managed to rip the interior door release handle off the inside of the driver's door of my Sienna, and they cross-threaded a lug nut on my Maxima. That only cost two days of productivity screwing around with the repairs.

I also got a set of tires that had been deformed (at least one of them) during shipping. Apparently, when they ship tires from overseas, they compress them, and they don't always bounce back properly (they said belts get deformed or something like that). So I took a 4,000 mile cross-country round trip with my car pulling to the left. They replaced all four tires when I got back, and that really can't be said to be their fault. Some guys have all the luck!

They should not have cross-threaded that lug nut of mine, and they should not have replaced your sensor without telling you. That I would fault them for. Still, I'll continue to buy from them.
