Can the response time of a TPMS sensor tell you anything about its battery level?

Yes.

Ha! April fools, got you…

The actual answer is no. Whether a sensor responds rapidly or slowly to the activation tool, it basically consumes the same amount of battery power. As a result, the response time does not correlate with the remaining battery life of the sensor. Let’s talk more about TPMS sensor signal transmissions and how to avoid limitations.
