Tire pressure sensor is working!
Had the RT out of the garage for the 1st time since before Thanksgiving y'day (1st time in the COLD this year). And after I had been out & about (after the car had been out in the COLD all afternoon), I fired it up to come home and LO TIRE PRESSURE comes across the EVIC. WHAT THE?
Wondered if it was a tire going down do to a nail or something so jumped out & used my hand gauge to see what was up (my brother had a bad sensor in his Jeep) and sure enough ALL 4 tires had snuck down to 27.5lbs. OOPS, last time I checked them was May.
Pumped em back up to 35 each, fired up the car, STILL had the light on. WHAT THE?
After 1 mile of driving it went out and has stayed out. Guess there's a smoothing algorithm in there.
