Low tire warning - just a quick question

[Gardner]

Cold weather hit and the warning system indicated the right rear tire pressure was low. I pumped it up but the warning didn't go away. After I drove it awhile, it finally "registered" and corrected itself.
My question: Why did it take so long? Do the sending units only work in certain intervals of time?

I think it's just a low priority unless maybe you're in tire inflation mode. They always take forever to update.

They only send out a short signal every so often, and only when the tire is rotating. If they were on constantly, the small battery in the sensor would be dead in no time at all. What you saw was perfectly normal.

The system tells you that it can take "up to" 15 mins for all 4 tires to register ..

Totally normal.

OK, thanks to all who responded. Wasn't a major matter but it made me curious.
