Hey guys I tried searching and didn't see anything but I have a 2019 Silverado with Fuel Maverick with Toyo 295x60r20s. I got a flat the other morning and had the tire repaired at a local shop, after the repair the sensor read 19lbs but checked out with the gauge to be at the correct PSI. Now the sensor went blank and isn't reading at all. The local shop is telling me the sensor is dead and they can't get it to read. I bought the VXDAS tpms tool for GM to no avail. Any help is greatly appreciated
