Corolla 2010 Tire Pressure Warning

[tlijun]

After changing four tires in Firestone for my Toyota Corolla 2010, the tire pressure light was on. Back to Firesotne, they told high tire pressure also makes the light on, they reduced tire pressure, the problem was not resolved. When turning the engine, the tire pressure light blinks about one minute first, and then stays solid.

This morning I try reset tire pressure by holding the tire reset button, the light blinks many times, not as the people told in this Forum it only blinks three times. I will drive it today, and see if the light will be gone.If the light is still on, I do nopt what should I check next. Can someone give me some suggestions?

I went to Firststone this weekend, and they checked with instrument. One of tire pressure sensors was broken, and they free replaced it, and then the tire pressure light was gone.
