DIY - Bypassing Tire Pressure Warning System (TPWS / TPMS)

[bronsin]

Hmm I bought a rim for my Yaris with a useable tire but no sender. What happens if the warning light goes off! Ok to put tape over it?

The light will come on eventually. It doesn't affect anything other than being annoying. You can tape it, or do the mod.

Thanks to them, I was able to make mine with a switch.

I did the latest tpms light disable as per post by yarisugi. I got a small DPDT from Radio Shack. Good thing I had a tiny pair of side cutters. I can flip the switch back and forth with the correct results every time. I did this and then put on some 14 x 6 BBS wheels on with 185/60-14 wheels and tires. The car handles much better than with the 15" steelies. I can chirp the tires now at will. It likes the smaller tires and lower gearing. Ya the speedo is off now, but I get 15k a year on my lease. Thanks to all from this post for the awesome, accurate work and reporting. I'll try and post a photo of the car soon.

I'm putting winters on this week, just did the mod yesterday. I still can't find my digital camera, but the pics/schematics shown are plenty to get it done.
