Code C2120

After my C5 had been sitting for about three weeks, I drove it last night. After about 3 miles it flashed code C2120. I reset it, and drove another 20 miles. Let it set for about three hours, then began driving home. After a few miles it threw the same code again. List describes it as TPM System Malfunction. For the computer challenged, what is this, and any info on the details as to why this is happening, and what I need to do to correct it. My signature has the list of mods to this vehicle.

Thanks in advance
Benny

Means the receiver has not received any tire pressure monitor info for 20 minutes. I suppose the first place to start is to see if can reprogram the sensors.

Thanks a lot. I have recently took off my regular tires/rim and installed Z06 rims and Nitto R's for some canyon running.
