Trying to reset the TPMS in my car. Took me forever to find the button, but find it I did. I followed directions from Toyota about engine off key on and holding it until it goes off, but mine won't go off... I've checked all tires, and they are at 36-38 PSI, any assistance would be appreciated

 

If the light won't go off one of the sensors might have failed internally and will need replacement.

 

Turns out this is exactly the issue. Previous owner replaced a sensor with a standard valve stim
