Here's my contribution...

I had aftermarket rims and apparently the driver side rear sensor died and the dealer wanted my second born to replace the sensor. After driving around for 3 months with the annoying light and researching the web. I finally found a fix to get rid of the annoying light. Note the fix is to make the low pressure light from coming on. It still store the DTC code but won't trip and CEL.

I been reading the Yaris forums and it look like the car uses the same TPMS ECU as the xB. I'm sure this fix will also work.

Here's the link to the PDF I made.

Let me know if this work for any 09's xB's and other similar vehicles.

 

wow, might have to try this and finally take the tape off my tpms light.

 

Mines been on for months, i'm not sure if it works the same with the tc.

 

I'm sure it does. The pink wires goes to the instrument cluster and it need a 5volt to keep the light from coming on. The black wire next to the pink is a 5volt source. Just jump the two wires together.

 

Will that cost a short if we put 5v from the black wire .. since the 5v from the black wire might be a power source for sth else .. ?

 

Nope doesn't cause a short since I did this mod to my own vehicle and the light been off.

 

Would be nice to know if it does
