TPMS with Torque Pro? Any figure this out?

iirc, scangauge shows pressures, so the sensors are there.

 

You can try this app. Tire Assistant - Apps on Google Play

 

It's 2019 and Tire Assistant still doesn't work with the Prius3 (I've got a 2012). I know it's probably the OBDII adapter (mine works great with Torque Pro), but just letting others know. I can't believe with all the things that a Prius monitors and tells you about, it won't let you know your tire pressure (just a warning light for "too low" and "too high").

 

Tech stream has different psi reading vs my $25 rotary tire pressure gauge every time

 

The ELM doesn't support the K-bus that Toyota uses, thus Torque/Carista can't see TPMS. You've got to use Techstream to see TPMS.

 

That app requires access to your photos, contacts, location, contacts and videos just to launch the app. Let me tap ‘yes’ to give it full permission to access all that so I can get my tires’ pressure

 

Only the new ones do, starting a bit over a year ago. Beware that old units in some retail stocks might not have new enough firmware.

Many of us with older units managed to snag a free firmware upgrade offer in late 2017 that included TPMS pressure and temperature readings. Now that something in my system is getting slightly flaky, this has been useful. While I haven't tracked down and fixed the problem, at least I can see that the problem is a missed reading on a specific sensor code, not a low reading 'somewhere'.

 

Yap, all kind of permissions, but perfectly fine for my use. I have a dedicated cheap Android phone I use ONLY for car diagnosis. No SIM card, no GPS enabled, no personal information stored in the phone, not even Google account on this phone.

 

How do you get apps on it (like torquepr app) without a Google account in the phone? You can message me privately if you'd rather.

 

I have used an Android phone without Google account for some time, but if you use it often it may not be easy from time to time. If you are willing, you can Root the phone and load custom ROM to make it totally non-Google. You can sideload APK without going through the app store. You can also download from the app store other than Google store without having a Google account. That said, the easiest way may be to create a google account just for that phone to log on to the Google Play Store and never put any kind of personal information tied to it. I have ~10 different Google accounts I use for various purpose.

 

I don't think I've tried sideloading a paid app like Torque pro.
Like you said, easier to have another dedicated account.

 

There’s a way for that, it’s rooting your device. Paid apps can then be downloaded for free

 

Yeah, for a paid app, there are some snugs. You can install app like Torque Pro free from a site like aptoide, but most often verification fails, so you can't use the app. Also, apps cannot be automatically updated for those not downloaded from Google Store. It will be easier to just create a single use anonymous Google account for those situations.

 

After using Bluetooth OBD2 and app, Scan Guage II, Techstream (though it failed to install for me) to see OEM TPMS data, my conclusion is none of them are as useful and easy to use as this external TPMS. Real-time pressure any time, driving or stopped. No reset or programming needed. It is accurate within 1psi from internal TPMS value or hand measured values by a tire pressure gauge. Although its durability is a bit questionable, at $40 for a set, it is cheap enough to be replaced if fails. Make sure not to keep the sensor on if you are washing tires. And keep anti-seize on the thread of the bulb stem in areas with road salts. So far it is working far better than internal OME TPMS.

 

I found a way to display Prius TPMS information on my phone, including all tire pressures, temperatures and threshold settings. You can do this using OBD Fusion. The app itself is only $4.99, but an additional $9.99 is required for the Toyota Enhanced Diagnostics add-on specific to the year of your vehicle. This allows you to display most, if not all, of the live data Techstream provides. The only downside is that you must select a specific module, such as TPMS, when connecting to your adapter. This means you can't see all your default PID's and TPMS PID's at the same time. I'm using a vgate iCar Pro Bluetooth 4.0 (BLE) OBD2 adapter with a gen3 2010 Prius. The app works well. Who knows what the actual PID information is to put into other apps like Torque Pro to get TPMS values, or if this can even be done. That is still a mystery.

 

What is the simplest, low cost way to read and set the TPMS tags in a 2013 "Prius V"?

I have an "Orphaned" wheel after buying two new tires. One of my two extra wheels had a tire with a bad sidewall. I had one of the new tires mounted on that wheel. This leaves my Prius V with three wheels (+the donut) with correctly registered IDs in the TMPS system, and one wheel with the wrong ID. My intent was to disable the TPMS completely, since I move wheels around a lot, and I am too cheap to pay for the service to relearn the correct TPMS sensor IDs.

I have had no luck disabling the TPMS system using the Gen 3 hack that shorts Pins 5 and 7 on the TPMS module. This does not make the light go out. I discovered that the TPMS module for the Prius V has a different part number from the TPMS units on any other Prius variants.

Here is the thread where I have been trying in vain to disable the TPMS:

I need to disable my TPMS system | PriusChat​

So I am going to "Stop Worrying and learn to LOVE TPMS" (Apologies to the movie Dr. Strangelove).

To do that, I need to get the IDs off the sensors in each wheel (including the orphan), and then make sure that the 5 sensors stored in the TPMS match the wheels that are actually on the car. This is a lot easier to do on American cars, using a $13 tool pressed against each tire to force the sensor to broadcast its sensor ID. It is something called "Re-learning".

None of the android apps I have tried seem to be able to see the sensors (Including Torque-Pro). I Even tried "Tire Assistant" which claims to be specifically designed to read TPMS sensor data from Toyota cars.

I think that Techstream is the way to go. I bought a copy on Amazon 15 months ago ($40), and I never got the install to register its key on my Windows 10 laptop. I also lost the cable. There are listings to buy Techstream on eBay for $20 where they do the install remotely, which I am OK with.

WHAT I AM LOOKING FOR:
Can someone recommend a place to purchase Techstream and a cable for a reasonable price, and minimal hassle? I have looked at Carista, but I am not convinced that it will read the TPMS sensor data on a Prius V.
