Tpms on 2021, store 2 sets of codes

We do twice annual tire swaps. While I am no expert on this matter, I do know that the tire shop walks around the car with a device that scans each tire. Then they plug said device into the OBD2 port to program things. It literally takes 2 minutes.

We get this free (we bought one set of wheels/tires at Discount Tire so changeover is free for life). I assume there would be a nominal charge otherwise at a tire place. We avoid the dealer for tire swaps because $$$$.

 

Contact them again and tell them that the snows have "real" Toyota sensors on them too.
And then see if they have an answer for your real question.
They probably won't.

So......contact Toyota directly at the "warranty help line".
They can help with other things too.
The number can be found in the manuals that came with your car.

 

So far, I've not seen any posts here at PC claiming to have programmed in 8 TPMS sensors, of any kind.

a piece of black electrical tape over the light is the go to solution for snow tire use without reprogramming the sensor ID's for those more sensitive to dash lights of any kind.

 

AFAIK, North American models of PP and other Gen4 do not have 8 TPMS ID spots. But for EU models (not sure about Japanese models), Gen4 (and presumably Prius PHV) has been shown that they do have 8 TPMS sensor slots on ECU enabling easy switching of two different sets of wheels with registered TPMS sensors.

If you can convince your wife, then the easiest and cheapest solution is to ignore the TPMS light when you have winter wheels/tires provided NY allows having the TPMS lights on for the state inspection. According to this article, NY is one of those states that mandate the working TPMS in order to pass the state inspection. So, make sure you don't have to have the car inspected during the time you have the snow tires on. Vehicle Inspections and TPMS Sensors | TireBuyer.com

TPMS is subject to inspection in states where vehicle safety inspections are mandated. These states are Alaska, Utah, Missouri, Pennsylvania, Maine, New Hampshire, Louisiana, Vermont, West Virginia, New York, Virginia, North Carolina and Texas.
​

If you want to have a working TPMS with your winter wheels, and don't want to visit tire shops twice a year, then you can DIY the reprogramming if you invest in the TPMS Tool like Autel TS508. It will cost you a few hundred bucks, but it will pay for itself after a few years of winter change-over. That's what I do, I have three different Japanese cars (Toyota, Nissan, Honda) all requiring OBDII interface TPMS tool to reprogram TPMS sensors. After a single year of the tool use, it paid for itself. Also, if you buy a kit for the TPMS tool, it often comes with programmable TPMS sensors that you can use on almost any car, so your initial cost on TPMS sensors will also be covered by the purchase.

Whatever you do, don't have the dealer reprogram the TPMS sensors, they will charge arms and legs for what takes a few minutes of computer diagnostic tools. Any tire shop with a TPMS tool can do the TPMS programming. The cost varies but some do it for free, most charge the same fee as a tire rotation. If you have to take your car to a tire shop to have the TPMS sensor programmed, then as might as well, you can have them swap the tires for you. The cost is usually the same.

 

If you have a Mazda you'd be fine*, with Toyota not so much. Maybe a surreptitious piece of electrical tape over the light would placate your wife?

I faced this issue in November 2010. Dealership mechanic asked if I wanted sensors on the snow tires, while emphatically shaking his head. I declined the sensors. Still using those tires lol.

* Somehow Mazda's managed to use in-the-wheel sensors, similar to Toyota, but swapping a set of (so equipped) wheels/tires on, just a few minutes driving and the car'll find and use the new sensors.

 

I had the Prime inspected in NY this year with the TPMS light on and it passed.
Still probably means nothing if I shop refuses to pass with the TPMS light on.
I double checked and my search revealed

""" YMMV and usually does """


I also just tired the procedure in the link provided above and all it did in my car (and I suspect after watching the video in the european version too) is reset the TPMS pressure to the tires current pressures. drats ....
I must have tried 10 times. with foot on brake, with ODO showing, pressing constantly, holding the long press on each of the 3 screens involved. All had the same result if pressing a different way move to the next screen.
My TPMS dash light is still on.

edit: Still, would be interesting to know which (if any) after market TPMS sensors can be programmed in with techstream.
A couple weeks ago the OEM pacific sensors were $30 for a set of 4 on ebay. As it's a question that comes up occasionally here.

 

In this thread on comments #3 and #13, I explained three methods currently available for Prius Prime owners to DIY TPMS sensor ID registering and their costs.

FWIIW: I install TPMS sensors on my winter wheels and use a ATEQ TPM QuickSet to store summer and winter IDs for two current vehicles, although it can support up to 4 vehicles. Been using the same device for over 8 years on multiple brand vehicles over that period. When I change wheels for the season, I load the IDS for the corresponding wheels/sensors via the OBDII port under the steering wheel. Only takes minutes to do and avoids having to go to the dealer or seeing a flashing light. But it does require a PC to store the IDs from which you load the QuickSet for the wheels and season.

I just finished downloading from my 2022 PP the IDs of the TPMS sensors on the factory wheels that will be mounted with winter tires this week. I also manually entered the new sensor IDs for the new sensors I purchased for the summer wheels that will get the factory summer tires.

If buying TPMS sensors, I suggest the threaded type:
PN 42607-33050 that also requires a Fitting Kit PN 04423-33060

A lower cost option since it does not require a Fitting Kit, is the rubber plug style like on the factory wheels: PN 42607-02050

 

Just as a side note:
In most driving conditions, "snow tires" actually have WORSE traction than All Weather or "Winter" tires.

 

The situation is:
In most places around the US, roads are plowed soon after a snowfall and the time you spend actually driving on snow is minimal. If there is any ice or hard packed snow left, the snow tires often have worse traction......and they aren't as good on dry pavement either. If you live where you DO drive on actual snow covered roads, or off road, the snow tires are fine.
If not, you are just fooling yourself and likely wasting time and money.

Why would your "ground clearance" change with snow tires ??

 

I'm not sure he said that; maybe just that snow tires are half the battle, and the Prius' low ground clearance is still liable to get you stuck.

Lots of definitions there. Maybe just take it tire-by-tire? I appreciate more aggressive tread can lose traction on bare pavement sooner: I've noticed (with some), it's easier to spin the wheels when starting, say making a left turn quickly from a standing start.

Still, our current Michelin X-Ice are very well behaved on clear pavement. And the softer rubber compound helps on frosty/icy conditions.

 

Yeah don't tell anyone, but I recently put on our (2010 purchased) X-Ice for the eleventh year. I did take one down to Kal Tire, asked if it was time, and they said judging from condition and tread depth, they've got at least one more year. Think I'll be shopping there, when I do replace.

To be fair, the car only has around 93K kms in total, and the snow tires maybe a third of that?

 

But they are not Michelin X-snow tires.

Which is pretty much exactly what I am saying.

And I think you are right about the ground clearance thing.
