They have reseated the tire a couple of times. Can the air pressure sensors have anything to do with this ya reckon. The car is up for sale by the way. Only 57,OOO miles and clean condition. Asking 9500. Its loaded and red with chrome wheels. Sharp looking car.


Is the tire actually flat or the light comes on telling you it is low? If the tire isn't actually flat, I'd think it was the sensor.

I just got 2 front tires the other day. On the counter in the tire shop was a lil bucket full of those air pressure sensor valve stems. They go bad. They are battery powered and have to be replaced periodically. Hopefully you don't have to get it done at a dealer.
