I believe that the 2005 C6 platform uses a different sensor all together.
The sensors are programmed with a hand scanner at each wheel. The C6 doesnt have the option of reading DTCs or programming sensors thru the DIC..

C6 is completely different.

Sorry guys - I have been busy and haven't had a chance to get back here. My local tire store is the busiest in Myrtle Beach and I am assuming they can break my tires loose and stick in the new sensors, and then sync, set them up so all shows well in the display. I really thank you guys for my lessons here as I know nothing about all this new electronic stuff in cars. Heck, my Harmonic Balancer crapped out and I tried to change it myself. When I got to the part where I had to take apart the whole front end I with special tools I gave up and took it to my dealer. Again - thank you all.

There are several things going on here.
1. You need to read and post your Diagnostic Trouble Codes (DTCs). Its simple and can tell you a LOT about what is going on with your car:
2. The Tire Pressure Sensors may just need reprogramming OR like others have stated, the battery in the sensor may be dead. You can dig the battery out of the sensor and solder another one in but most people just purchase new sensor. Your sensors are SCHREDER Sensors and operate at a specific frequency.
You MUST use the first design sensors and fobs.
However,,,, you can purchase a KIT to up-grade to second design RFA, FOBs and TPS.

If you are not intentionly spinning the tires or loosing traction and you are expierencing Active Handling, you could have a bad Steering Wheel Position Sensor (SWPS)
Reading the DTCs will help diagnose that/
READING YOUR Engine Diagnostic Codes
The Diagnostic Display Mode is entered with the following procedure:
1) Turn on the ignition but don't start the engine. NOTE! You can read the DTCs with the engine running and or driving down the road but it can distract you. BE careful! Some DTCs clear themselves when you turn the ignition OFF!
2) Press the RESET button to turn off any warning messages. (i.e. door open, trunk open ect)
3) Press and hold OPTIONS
4) While holding OPTIONS, press FUEL four times within a 10-second period.
Initially, on-board diagnostics go into an Automatic Mode which shows diagnostic codes in a pre-set sequence: PCM - TCS - RTD - BCM - IPC - RADIO - HVAC - LDCM - RDCM - SCM - RFA. All codes will be displayed for each. ( i.e. PCM = 4 codes) If none are present in a given module, you will see No More Codes on the display.
There are two kinds of diagnostic codes, Current and History designated with a letter suffix, “C” or “H”. A current C code indicates a malfunction is present and active in the module displaying data. A history code indicates a problem existed sometime in the last 40 or 50 ignition cycles. When not accompanied by a current code of the same number, it's potential evidence of a previous problem, now resolved, that was not removed by clearing the codes.
More likely it's an indication of an intermittent malfunction.
Intermittent codes are the most challenging of the diagnostics. An intermittent code may have happened once, may have happened more than once but is inconsistent or may be happening on a regular basis but not at the time the codes are displayed. History codes can also be caused by a current malfunction in a system that is not operating at the time codes are displayed. An example is the rear window defogger which doesn't operate until the Body Control Module detects engine rpm. For history codes set by a module that does not operate with the key on and engine off, a special diagnostic tool called a Scan Tester is necessary to properly diagnose the malfunction.
Once the system has displayed all modules, it goes into the manual mode which allows selection of each module using combinations of Driver Information Center buttons. Manual mode can also be entered during the automatic sequence by pressing any button except English/Metric (E/M). Once the display shows Manual Diagnostics, select a module by pressing the OPTIONS button to go forward or the TRIP button to go back. Once a module is selected, a code is displayed, and if more than one are present; press GAGES to go forward or FUEL to go back.
To exit the diagnostic mode at any time, press E/M. If you want to erase codes in a given module, press and hold the RESET button To reset the codes once in manual mode, press and hold RESET until it displays NO CODES Press OPTIONS to go to the next module. Repeat the steps until you have reset the codes in all the computer modules.
NOTE!! Only reset the codes IF you want to - it is NOT necessary to do this. Clearing a code does not repair a problem. You are simply erasing the evidence of it in the module's memory. If you clear the code/s, and extinguish the Check Engine Light, your emissions status ready will NOT allow you to pass an emissions test until you have completed the required driving cycles.
Once you have the codes, the next question is: What to do with the information?
First, consult the factory service manual. Any serious C5 Do-It-Yourself owner should invest in the Corvette Service Manual of the appropriate model year. The Service Manual is really a requirement if you want to understand and work on your C5. You can GOOGLE the DTC and also find information on it.
Here is very good site that explains the DTCs:

Make sure to include the H or C suffix!!

I had 8 codes come up and all had an H after them except the Left Front Tire Sensor which had an H and C. Plus, I also have the DIC showing Service Tire Pressure Monitor. Just changed tires and had the original sensors put back in. Seems only one giving me a hard time is that front left one. Maybe I should get the batteries to replace them all while I'm at it??? The vette is a 2000. Can only assume they are original? Also, having problem with 2nd key FOB not wanting to work even though we replaced both batteries and tested them for being new. Any thoughts on that 2nd FOB also???
