Toyota Repair: 2007 toyota sienna LE 8 pass. 2 WD, flat tires, pressure indicator

Question
My tires spun out a little after pulling away from a stop sign in the rain.  The pavement was wet.  Later that night when I started the van up again, the low tire pressure indicator light was on and has remained on even after my husband checked all of the tires and the pressure was fine.  I tried holding the reset button next to the steering column with the car in "on" position but the light still won't go off.

Answer
Depending on what model Sienna it is it may or may not have a spare tire(run flat tires do not have a spare) if there is a spare it may also have a tire pressure sensor so it should be checked as well, if all the tires are inflated to about 35psi then that's about all you can do, if the light still stays on you should contact the toyota dealer for assistance, the onboard tire warning system should be checked for trouble codes and for any sensors that may not be reading, Toyota has issued some service bulletins since there are some known issues with the TWPS system, if the Sienna has less than 36,000 miles on the odometer then it may be covered under the warranty.
