Toyota Repair: 2006 sienna van-tire pressure warning light, tire pressure sensors, toyota dealer

Question
had 4 new tires installed-tire warning light stays on.Tire pressure is stat-How to turn the light off?

Answer
The first thing to do is to make sure that all tires including the spare are inflated to 35 psi, when all tires are inflated to this pressure the light will turn off after a few minutes, if the light does not go off then there is another problem, it's possible that one of the tire pressure sensors was damaged in the process of installing the new tires, what I would recommend is to have the toyota dealer have a look at this and connect the techstream computer to see if all the sensors are reading and if not, determine which sensor is not reading and then replace that sensor.
