Whew! Crisis averted.

A few days ago, during an out-of-town trip, I noticed that one sensor stopped updating and by the end of the day, the display for that sensor went dark. Typically, the latter happens when the battery inside that sensor runs out. The other three tires were still reporting temperature and pressure values so it's unlikely to be a problem with the receiver.

So that night, I took out the nonresponsive sensor and replaced the CR1632 with a new one. I know it's a new battery because I tested it first before installing it and it showed around 3.3V.

The next morning however, the sensor reading for that tire is still blank. So I removed it again and checked the battery. To my disappointment, the voltage is now down to 2.5V! So the sensor is draining the battery somehow. A closer inspection does not reveal any water intrusion. I always use silicone grease on the O-ring and the cap threads so it's simply impossible for water to get in.

So long story short, I started tearing into the tiny PCB. Since it's dead anyway, I can't make it any worse. I just blindly re-flowed the solder on everything on there. It's a challenge as everything is so tiny. I reassembled everything and inserted another new battery and screwed it back on the tire.

About 2 hours later, I went back to check the TPMS receiver and I was elated to see that the "dead" sensor is now sending data again.

I don't know if this is going to be permanent but I'm hoping that it is. I guess these sensors are subjected to unimaginable abuse.... them being on the tires and all, so maybe a cold solder developed. Anyway, time will tell if the fix holds. I'm just glad I don't have to replace the whole TPMS. Not yet anyway.
