TPMS Battery

[Grumpy Goat]

Good questions and I'd be interested to know the answer too. The two systems should not have anything to do with each other so it may be just coincidence in your case, and it may be that the battery is going ... Maybe others have more insight into this.

I was on YouTube looking for info on where exactly the sensors are located (in anticipation of future tire replacement) and came across a few videos on battery replacement. I didn't watch any of them but you may want to do that and see if they mention symptoms of a dying battery or even battery life, and see it that applies to you.

Either way you may have to remove the sensor and change the battery just to be sure that you have continuous service. For me, the TPMS is a great safety feature, not so much for telling me the pressure in the tire at any given time, but more to warn me when my tire is losing air due to a puncture while I am riding.
