Yesterday, the TPMS monitor said that there was no signal from the left front tire. Today, the ABS light came on, the Traction control light, and the AWD system was disabled.
Are all these functions controlled by a single sensor? I am hoping that it is just ice and snow build up as it was above freezing for a day or two last week, but has been below freezing since. I do live in a snow belt.

 

Replaced the right front hub.
