My problem started with tire pressure showing - - on all tires. I had all sensors checked and reset several times. I know the sensors are working because I will get a low tire light when I have a low tire. Then just recently my key fob(s) stopped working but only when it is cold out or after the truck sits overnight. After researching I found that the receiver for the tire pressure is the same as the key fob receiver and is located under the headliner. Can anyone tell me if I am understanding this correctly
