My tire pressure warning light came on in my 2017 Yaris ia. The tire pressure in each tire was 30 vs 36 (33 rear). I filled the tires today and the light stayed on. I turned off the light. If there still was a problem would the light come back on?
Yes, the light would come back on
For some cars it takes a couple miles at speeds over 20 mph for the light to turn itself off.
