Add to above - also check spare !!!There is no reset button. The light goes out when your tire pressure is within the psi the TPMS is set for. You'll need to check the pressure of your 4 mounted tires. If your tires are properly inflated and the light is still on, one of the sensors is bad.
My tire pressure light came on this past week. I checked all tires and found my left rear tire had a big peice of metal stickinbg out, the tire pressure indicator did its job. But i switched out with the spare and whether the spare is back on or not the light just stays on. I want this off so i can tell for the time being, the tires i drive on arent losing air. Any help? Thanks forum!!
