I used to sell the tire pressure system and also installed it for the new owner when they bought from me. Many many times the valve core stem was not in the proper position to activate the sensor, or just barely in the right position and the sensor would give a reading, but after a short time would stop sending pressure or temperature. A minor adjustment of that core stem up a tad, I'm talking a smidge would fix the problem of the monitor receiving a signal. In talking with the system company, most of the returned senders worked perfectly on their test valves and they could find zero issues with the returned part. That small valve core causes a lot of problems and it is the easiest to fix. But, many folks just blamed the TPMS and tossed their hands in the air and gave up, such a waste of a great product.
