When the tire sensor warning light on the dash illuminated, I attached my OBD2 diagnostic device to my car's computer and it gave me the trouble code that I used it to look up the problem on-line; but, it could not tell me how many of the sensors failed. When I got to Toyota, they inspected my car and found three bad sensors. I had them replace all four sensors (I do not want to have to revisit this issue for another 145000 miles). All sensors are working properly (as of Oct. 29, 2019).
