    The Prius sold in my country comes from Japan. It does not have built-in TPMS. Getting the original is a bit pricey. So I opted for a more affordable version which if broke or stolen, I am fine with getting replacement.

    Here is a simple video of unboxing and installation. Price is around 15-20USD sold in aliexpress.



    BTW, this works for all cars.

    I’ll trade you red wine for your set. My tpms light came on yesterday with no flats so one of the batteries is low on charge. I don’t feel like hunching down to press the tpms button at the moment to try troubleshooting

    Lol...shipping would probably cost more than the unit. But yeah, nothing beats original TPMS as it's more integrated into the car.

    “More integrated” meaning car not able to show each tire’s psi and temp, and that’s higher value than aftermarket with more detailed status? :ROFLMAO:

    It's more subtle. Minimalistic, as it integrated into the car dash. Unlike what we have for third party devices, we have another piece of the device lying on top of the dash.

    I wonder what is the weight of these caps. (Knowing that during tyre centralization 10g is used.)
    Most of the cases I would not need this info. Can it be get from Techstream?

    Techstream can display each sensor's detected pressure, but afaik doesn't what corner of the car the sensors are on.

    With LRR tires, heavy caps should effect tire balance. Techstream doesn't have a weight measurement system of caps, hell it doesnt even tell you location of sensor is on location of each wheel.

    I know that Techstream cannot show caps’ weight. It’s sad that the position is not showed. Anyhow, I cannot recall any occasion when I’ve missed the TPMS - though my Prius has it.

    Carista does this as well, but which wheel is which is the issue.

    Let half of the air out of one of the tires. Before doing that, have a working air compressor ready to go.

    Thanks for the info. I will send the car for wheel balancing and alignment later.

    Maybe to identify where the various sensors are?

    @Grit didn't quote this, but I think that's where he was going:

    With the air pressure dropped, you can track down which sensor number corresponds to which corner.

    Another thought:

    Some ScanGuageII owners were sending their units back for a free reprogramming, that allowed them to display tpms sensor data. The SG has for values displayed, in a square pattern. So you could arrange them to be positioned like the car's tire locations.

    Personally I can't get to excited about this. Also, I run snow tires for 4~5 months without sensors, get by.

    You mentioned that you missed the TPMS, so by letting the air out enough that will make the light come on.

    I wrote I cannot recall any occasion when I missed it. Sorry if my English is not good enough, I wanted to write, that I don’t find TPMS very useful.

    For me, TPMS is not really important until you need it. It's like insurance. As someone who occasionally check the tyre, you would be your own TPMS. However, there are times like when you are in the middle of driving and have a slow leak. Having TPMS will allow you to be notified before the air totally runs out and you can avoid accident.

    Another use of TPMS is for drivers that do not bother with checking their cars. A lot of women and men just use the car and never care to learn about things like engine oil and tyre pressure. They rely on workshops and their husband or father to take care of the car for them. Hence the need for TPMS to remind them of low tyre pressure which they can remind their partner to pump air.

    I don’t want to say it’s absolutely useless, though I’ve never needed - whenewer I had flat tyre it was a quick one. And it happened 3 times in the last 30 years.
    I can imagine more usefull tool. (TPMS is a must in Europe since 2004. Parking sensor, back camera, BLIS are not.)
    By the way if the tyre getflat quick, TPMS will not help to avoid accident. And even if it is slow one, driver should be able to recognise it before it gets so dangerous to cause an accident.
    It was more sold as a comfort equiment, you don’t have to check tyre pressure to recognise if it’s not on the expected pressure. (And flat tyre may increase the fuel consumption, but driving style has much bigger effect on that.)
