LOW TIRE PRESSURE INDICATOR

2000 Toyota Sienna

Electrical problem
2000 Toyota Sienna 6 cyl Two Wheel Drive Automatic 84000 miles

My 2000 Toyota Sienna is running very well. But I have one problem with the Tire Pressure indicator. When I drive more than 50 miles at Freeway speeds, the indicator just lits up. But when I check the tire pressure, it is just company prescribed pressure. I have mentioned this to the dealership when I take my van for regular service. But I guess the problem I had mentioned to the service attendant is not exactly explained to the mechanic. They check everything and say things are looking ok electrically. But the problem still exist. Also, after the light lits up after 50 miles, if I stop and switch off my vehicle for few minutes then proceed, the pressure indicator lits up within 20 to 30 miles or so. Longer the time I stop, longer the light stays off, but 50 miles is max. I am now used to ignore this light whenever I travel far. Does anyone have any idea about this?

Thanks

Hmm I belive that your tire pressure might be uneven?
If your tire pressure is a bit high or bit low light might come up also one of your tire might have a slow leak.
Hope this helps

Does this have anything to do with Sienna's engine oil sludge problem?
