I have a 201 Corolla. My mileage is 93,000 miles now. A few weeks ago my low tire pressure light on the dash came on. After I reset it came on again after a week . I kept checking the tire pressure and it was right on . So a couple days ago I took it in where I bought tires about 8 months ago . They have the scanner tool and found 2 of the tire pressure sensors were bad . So i went and had them replaced . The total price was $130. He mentioned about changing the other 2 tire pressure sensors but I will weight until they start acting up.
