TPMS Sensors suggestions?

There are two types of Toyota sensors; the car works with either, but only the newer sort can be registered via the user interface rather than with a scantool. That's the only detail I'm aware of, but no specific info on what you'll find from 3rd parties.

 

Many newer cars automatically check in the TPMS & identify their location so that you don't require a scan tool anymore. iirc all that's required is for the car to be in motion above 20mph for ~20 minutes. Both of our vehicles are from 2018 & soon as we change from summer wheels to our studded set, the TPMS auto check in - in this fashion. Side note .... at 6 years - the TPMS batteries have started going ... so best to change them out before that length of time - typically when the tires wear out.

When one TPMS sensor fails - REDI-Sensor.

 

The part number I have in my notes is 42607-02070. Add "-VK" (vehicle kit) for a pack of 4. Originally found that in the German Prius price list, and I believe that's what I ended up with on my winter wheel order (which I don't have to hand).

List price in the brochure for that is €225 for the kit of 4, so expect cheaper than that online, but I'd suspect anything less than half that of being fake. (Mine weren't priced separately from the wheels+tyres).

Don't know about that 0E090. Quite possible they've got different production and part number for spares in different parts of the world.

I think Toyota may have stopped making the older sort by now.

Looking on the US Toyota parts site, that shows me the same 02070 part when I search for TPMS for the Prius:

Tire Pressure Monitoring System (TPMS) Sensor

But "what this fits" for the part says "2 models, 10 variants between 2023 and 2024", which would have to be ONLY the Prius. That's a bit odd. In Europe the 02070 is pretty standard, I think, not some special Prius thing.

Maybe that's come out of the international specs, and not been replaced with a local substitute by Toyota USA - something they'd normally do?

 

I'm also seeing 0E090. It replaced 47010.

The 2 models, 10 variants doesn't work for a Prius. Anything that fits on all US Priuses should be 2 models, 18 variants between 2023-2024.

Prius: FWD LE, FWD XLE, FWD LTD, AWD LE, AWD XLE, AWD LTD(6)
Prius Prime: SE, XSE, XSE+(3)
(6+3)x2=18
(I double checked this on a couple parts common to every Prius, but only Priuses.)

 

But are you seeing anything saying that those are Prius-compatible? I imagine they might well be, but the autoparts.toyota site isn't showing the 0E090 up for me when searching with a Prius selected. Just the 02070. (which replaced 47020, apparently).

 

Ok, now I'm starting to see the problems. There are some errors in the autoparts.toyota database. Not every gen5 has a TPMS sensor fitment. It's obviously an oversight. My variant(AWD LTD) is one of the variants they missed, so 47020 wasn't showing up for me when I searched by my VIN.

Here's what the autoparts.toyota database currently says:
LE, XLE, XLE AWD, SE, XSE - 47020 is listed
LE AWD, LTD, LTD AWD, XSE+ - 47020 is not listed

As you can see, it must be an error as there's no rhyme or reason to which ones are excluded.

But if you use SparksParts(which uses a different Toyota parts database), all Priuses are listed as using the 47010/0E090. The 47020 is listed in their database, but they don't include any fitments for it at all.

And then if you go to MicroCat, it gets even more confusing.
47010(0E090) - all US except the E/G Korean spec, the European HEV with the old 1.8L
47020(02070) - the E/G Korean spec, all European PHEV
(apparently Japan doesn't get TPMS because nothing was listed for theirs?)

I can't find any sources with the mhz specs for any of the four part numbers.

So I basically know less now than when I started.

 

Ah, of course radio standards are going to be a thing here. I recall the pre-delivery checklist mentioning that TPMS is disabled in production due to not being Japanese RF-legal. And US and Europe may require different standards.

I note I can't actually get 02070 by searching by part number on the autoparts site - only by searching for "TPMS" with a Prius selected as the vehicle.

So hazarding a guess, 47010/0E090 is the correct US part, and 47020/02070 is the correct European part. And everything else is errors?

I think you might be right about Japan not having TPMS. Can't see it in the Japanese manual - light isn't there in the warning light diagrams.

The sensors are operating at 433-434MHz according to the EU manual. I gather that's different from the US norm of 315MHz? If the US manual specifies frequency, I've not found it.

 

Yep, there we go. 47010/0E090 is a 315MHz sensor and 47020/02070 is a 433MHz sensor.

315MHz is outlawed in the EU(reserved for other purposes). And apparently the South Korean military uses 315MHz, which is why the Korean spec uses 433MHz. The 1.8L HEV for Europe probably lists 315MHz as an oversight as I don't think Toyota has actually exported any there. The only 1.8L HEVs that I know of outside of Japan so far are in Mexico.


What's been complicating this even more is that Toyota is currently transitioning to newer style 315 and 433 sensors. I think the old ones were a 2-piece metal unit, and the newer ones are single piece plastic/rubber. Or something like that. I also think the old ones need a scantool to be registered to the car, while the new ones can do it themselves. But I could be wrong about that.

 

Car Car Nut video I saw concurs with the gist of that, except that he has the new ones being 2-piece with rubber neck, while old ones were single-piece.

So presumably 47010 and 47020 are the old-style scantool-required parts and G5 Prius owners should be looking for 0E090 or 02070 specifically, depending on region.

(Or maybe there's an even-older part number for the scantool-required parts?)

 

I assumed any references to the 1.8L in the "European" manual were there to cover some non-EU markets, hence the non-EU frequency. I get the impression the manuals are effectively:

• "Japan" (all engine options),
• "North America" (2.0 HEV + 2.0 PHEV),
• "Europe + Rest of world" (2.0 PHEV + 1.8 HEV).

 

I suspect the scantool-required types are even older part numbers that predate the introduction of the Prius. I suspect the newer change in part numbers might be a change in manufacturers or maybe a change in manufacturing location. Either that or a minor design update now that the new style has been out for a few years.

And I'm sure I just swapped that 1-piece/2-piece info. I was searching through websites pretty quick(mostly different Toyota forums) and must've conflated things.

 

Clearly the scantool-required type pre-date the Prius. The change started around 2018, according to the Car Care Nut video.

I'm not suggesting that there are two types of post-Prius parts. Just that the 47010 and 47020 may be the the pre-2018 parts.

Are you seeing any reference that ever said that the Prius should have the 47010 specifically? Or just references to the 2E090, which is indicated as a compatible replacement for the 47010?

 

MicroCat(via toyota-tech.eu) only has 47010 listed for the US version.

 

Hmm. And when I did a bit more looking, I can't find any TPMS part on autoparts that has a large number of compatible models. 47010 has the same silly small number.

Are they really making that many sensor variants for different models?

Next theory - could it be that 47010/47020 are the factory-fit, and 2E090/02070 are the local replacement? The letter in the middle of the code suggests that to me. Factory parts tend not to do that, right? That kind of fits the pattern for oil filters...
