You popped the 10A ECU-IG fuse, which is in the fuse panel under the bottom of the dash by the hood release.

Oops, I got it totally opposite. My wife is driving the car today, will fix it tomorrow.

Thank you very much CTScott

I was just studying this TPMS sensor solution. Comparing photo #2 the the color coded diagrams, it looks like one just clips the brown wire and splices it to the white one, and that this would be easy using one of those press down splicers, and of course taping off the end of the other brown wire.

Please let me know if this interpretation is correct. Or if anyone has a picture of the completed splice please post.

Since this is reversible it looks like an easy solution.

Thanks,

Maui

Will this work if you have a bad TPMS? My light flashes and stays on.

I'd rather disable it all together, stupid shop wants $320

for one sensor

Yes it would make the light go away.

I did this over the weekend when i had my tires replaced. I had them pull the sensors out too. Worked like a charm. Thanks guys

I did this fix on a 2010 Yaris and it worked perfectly, so thanks a lot! But now I want to do the same on a 2014 Yaris (4 door hatchback) but I don't see the TPMS ECU behind the glove box. Does anyone know where it is? I couldn't find any free repair manuals online like there are for older models, cheapest one on eBay is $60...

There is not a simple solution for 3rd gen (2012+), as the TPMS ECU now sends the info to the cluster via CAN bus message, rather than by a simple single line driving an LED.

The third gens do allow you to easily relearn the TPMS sensors by simply pressing a button, so the simplest solution is to have a second set of sensors in your alternate rims.

tarkus · 12-05-2016, 11:48 AM

Is there not a way to short out something at the wheel/sensor end before it gets encoded onto the CAN buss?

This looks like yet another case of unnecessary electronic complexity being put into cars, which means more things to go wrong. I work in the very high tech semiconductor/software industry myself, so I'm not against advances in technology as such, just against technology which causes more problems in the long run.

Just did this mod

Cut the brown, press-splicer brown and white....worked perfect (after I plugged the connector back into the box - duhhhh)....

Thank you - this place rocks!

(I chose to not have the sensor replaced after I heard it bouncing around in the left front tire and would have to pay $60 for a replacement)

Juanalexis21 · 07-20-2017, 02:21 AM

Hello friend, let's see if you can help me! I have a 2010 Yaris sedan and I changed my tin rims for type S, I did not change the TPMS sensors of my original rims but the emergency rubber still has the factory sensor. The type S rings have their original TPMS sensors but the vehicle that had them. How can I configure the new sensors in my vehicle?

I know it's not a blog but I hope I can help. Grateful!!!

Sorry. I didn't read through the hundreds of posts. Just skimmed through and I didn't see that anyone had done what I did on my "09 Tacoma and '10 Yaris.
I removed the instrument cluster. It's very simple and just placed a double folded portion of electrical taped under the gauge face plastic film. Done.
This way nothing is eliminated if years from now you or the next owner wants the system in use.
It looks like the light was never there.

My apologies for resurrecting an old thread but I am having a problem with my TPMS on a 2011 Yaris.

The problem is, all of the pictures posted were on PhotoBucket and they purged all of their free user pictures.

The only pics lift are of Rick's on post #138.

I can happily try this one but I'd like verification that it worked from someone.

Also, would disabling the TPMS show up in the OBD2 scan?

thanks!

apmatzen · 01-18-2025, 03:40 PM

Does this work on a 2016 Yaris?

Walsh11 · 07-14-2025, 05:28 PM

I have a 2013 Yaris, anyone please tell me how to disable this abomination system lol. thanks
