Tires and Wheels problem
1999 Toyota Sienna 6 cyl Two Wheel Drive Automatic 103000 miles
----------------------------------------------------------------
Recently my wife drove the car and had a flat tire on the front driver side. We had replace a new one.
The problem is , whenever I drove my car on the freeway at a highspeed(above 60), the tire pressure monitoring system(tpms)indicator goes on. When I lower the speed, it goes off. What should I do?

Please help.....Thankyou.

was it driven with the tire flat or very low even on the rim?

could have damaged the sensor due to it being driven on.
