Service Tire Pressure Monitoring System

[08 Black Max]

I got that error msg yesterday in the middle of a thunder storm.
I do not have a code reader and do not have access to one.
I noted that I do not have a pressure reading from the Driver side rear.
I am guessing that the sensor in that tire has failed, is that the correct guess?
Any actions I can take to verify my suspicions ?
The msg is in the truck below and it is mechanically stock.
Does this fault require a GM dealer visit to reprogram the computer or can any shop replace the sensor and the error will correct itself or will my truck need to phone home at a GM dealer to be reprogrammed?
BTW tire pressure is good checked with a manual tire pressure guage.
Thanks in advance

Look in your manual. It tells you how to reset them. Might be worth a try.

Update:

I did nothing to the truck and or tire.

On Monday drove the truck to work; no warning lamp and no message and I am getting a reading on the dash for all 4 tires.

So is there a way water/rain could affect the sensor and or the computer that picks up the TPMS signals ?

Update to the update

My sensor acted up again in the rain today.
So today my truck paid a visit to the general
DX of faulty sensor in the tire.
$175.00 for repair and reprogramming the truck.
So now I hope the problem has been solved. I hope.

$175? I got four sensors for $100 with new valve stems. To program new it's just like after you rotate tires.
