Tire pressure code
While driving today I got the "Serv. tire mon. sys." message.
Checked the codes and got this one:
BO-RFA C2105 H C
A couple of possibilities: The sensors were rebuilt when I had new tires installed in April. Also, I had the right front off the car recently so I could clean up the brake caliper, but drove it several times without an issue before the message appeared.
So, now what?
As always, thanks for the advice.

You say your sensors were rebuilt. By that, I take it you mean the batteries were replaced? That's not an easy thing to do in the sensors for the '01 - '04 C5s. Perhaps the right front sensor wasn't rebuilt properly and failed very prematurely. You might try clearing the code and see if it reappears. If it does, you'll probably have to have that sensor uninstalled and rebuilt again (if that's possible) or just replace it with a new one.

The process of "rebuilding" that the tire shops typically do is to replace the rubber seal, the nut and the schrader valve. Batteries have to be "cut" out of the TPMS to replace them. ie they are NOT a plug and play thing. Here is a link to some pictures of both the early and late year TPMS:

And another link to a thread about replacing the batteries on the early year TPMS:

I have never read of anyone successfully replacing the batteries on the later year TPMS (01 - 04).
My guess is that your sensors are "original" and at 13 years of age have outlived their expected life (8 to 10 years).

Since there was no charge, they didn't do anything to "rebuild" the sensors. They simply left the existing sensors installed and replaced your tires.
If one sensor has gone out, it's likely others will follow, assuming all four were installed at the same time.
The sensors will have a date of manufacture stamped on them, but obviously you'll only be able to find out what it is by physically looking at them. The stamp will look like a clock (1 through 12) with an arrow pointing to indicate the month, and a number on either side of the arrow indicating the year (i.e., 0 and 3 = 2003). There's a couple of good pics of this in the first link in 8VETTE7's post.
