TPMS problem. Is my sensor bad?

Not sure what's going on with my TPMS. Its flashing on and off. Check the right rear tire and its holding air. Is my right rear sensor bad?

 

That is a real possibility especially if the truck is 7 years old or older. I'd replace all 4 if one is bad, around $80 on Amazon.

 

Truck is a 2016.

 

Yeah, the batteries may be failing on them in this time frame. Get new sensors

 

Is this a temporary state, or is it staying that way?
I ask because https://www.tacomaworld.com/threads/tpms-errors.744252/

Most tire shops (and many individuals) will have a TPMS tool that can check your sensors (without removing the tires).

 

Yep. Most likely DB (Dead Battery).

Do all 4. The others probably aren't far behind.

 

In a word - Yes. They have a battery. Battery dies after a bit.
