Tire Pressure Sensor Warning Light

I recently Replaced my last tires (245/75-16) with a taller tire (265/75-16). Since then, my tire pressure warning light keeps flashing even though I have reset the warning system as stated in my vehicle manaul, and, have even tried removing the negitive battery cable to reset the system. Nothing seems to work! Is there a proven method of achieving this without having the Toyota dealership charging an arm & leg to do so?

 

Is it FLASHING or STEADY?? Flashing indicates a broken sensor....Steady indicates your pressure is off.

If it's steady you need to set all the tires to the same pressure and then press the reset button (under the steering column).

 

Check your spare.
