When driving home last night, the tire pressure monitor symbol was blinking and the display said XX for the right rear tire. I was only a few miles from home so I drove home and check the pressure and it was 30psi like the other tires. This morning it was working fine. These are the original sensors that came with the car (2013) is this an indicator that they are going to give up the ghost soon or just some anomaly?

 

The sensors are only good for so long, and it looks like yours are due for replacement especially if they're 9 years old.

 

When mind started with XXX is warning telling you there batteries are getting weak, and time to replace them.

 

Had all of my TPS sensors replaced at the end of 2019 at Discount (batteries shouldn't be bad in just 2 years & change on a car that is only driven on the weekend during good weather, that is basically a garage queen.

Last trip out, rear drivers side XX along with a DIC message "Service Tire Monitoring System". Same as the OP, checked the pressures and everything is normal. Took it to Discount Saturday (same one that replaced the TPS sensors) to have them see if they could reset the system. Put the car in the TPS learn mode but after several reps and about an hour trying, they couldn't ever get the front drivers side TPS to set and get the horn signal to move to passenger front per the procedure. Left discount and decided to order a $13 tool from Amazon OEC-T5, same response, could never get it to set the first TPS..

Fast forward to today, pulled the negative battery cable and left it off for an hour or so (really got busy and forgot about it), after putting the cable back onto the battery, everything works, no XX, no DIC message all four tires reading pressure. Guess it just needed a good hard reboot.

Weird that I get on and here is a thread about the exact same thing I have been dealing with.

My dad got new wheels and sensors. Can you relearn them using the cars DMC?

 

You need a sensor activation tool on the C6 Corvette so the car can learn about the sensor. The tool is $13, or whoever installed the tires should do it for free.
