my tire sensor light came on showed one rear tire had no pressure then the other one showed that then after i stopped and checked the tires the light went off could it be that there was some snow or i
could it be that there was some snow ice on the sensor has not done it again
It wouldn't be snow or ice. The TPM sensors are inside and normal temperature fluctuations should not set them off. It usually takes quite a bit of variance over a length of time to set them off but the change of pressure due to driving may have done it.
