Hi - I have a Kenwood DNX 9980 on my '08 with 0 TPMS interference.
The batteries in the TPMS will weaken over time. They can last up to 12 years.
There is no way to test the TPMS battery.
On my '08 (purchased new) I changed tires and TPMS's for the first time in April 2020. The TPMS's were working fine, but I thought it wise to change them. So that was 33,649 Miles and 12 years.
The other guy who posted (hasn't been back since 2022) wrapped his Kenwood wiring with aluminum foil to help with RFI.
Hope this helps,

I'm swapping out my TPMS as they are original so maybe a weak battery signal is causing the issue. It stopped reading the RIGHT FRONT and then it came back on and started reading again but they are OEM so 12+ years old.
They were preprogrammed, all that had to be done was learn the wheel positions.
That's what the vendor said, they are pre-programmed. Will take each wheel in to Discount Tire to have them install the new TPMS. Hopefully that should help with the error message I got when it couldn't read the tire sensor.
Learning the wheel positions is done once they rims wheels are back on the car and you are rolling, correct?

They don''t have to be mounted in the rims to pair them to the car. You can just place the sensor on the ground, beside the wheel, but not near too near the old sensor that's already mounted. Put the learning tool up against the new sensor's stem, and press the button and the horn should chirp. Make sure you mark the new sensor with a piece of masking tape and write the position on it i.e LF, RF, and so on so that they get mounted into the correct rim. Doing it this way de-risks finding out that the sensors won't pair to the car after they've been mounted. Just a suggestion, since if you are supplying the sensors, Discount Tire has no responsibility if you bought incompatible sensors.

Thanks for the info! Only issue is that I am bringing DT one or maybe two rim/wheels at a time. The DT is located on such a steep driveway (rural mountain area) that my C6 would not clear it and would high-center. It's a badly designed driveway.
So how would I go about doing that if I only bring them one or two wheel/rim/TPMS at a time?

Pair them up - left front, right front, right rear, left rear. Write the position in Sharpie on the sensors as you pair them. Have them mark the wheels when they mount them and the tires.
I frequently get inaccurate tire pressure readings and occasionally my dash will explode proclaiming one of my tires is completely flat, Quick visual inspection confirms all 4 tires are just fine. I just assume that the 12-year-old TPMS sensors are failing.
I have an '05 that I bought with 32k on the clock. I doubt the TPM's were ever changed. I get messages of low pressure, tire flat on occasion. I check the tires and on the tires that I get a message on I let some air out and then refill to 30 psi. I know it sounds crazy but the messages go away. I am due new tires soon, I guess I'll spring for new TPM's.
I got this on TPMS.com. It's a Schrader 33700 and comes pre-programmed for the 2013 Corvette. The new sensor is on the left, the old on the right. The OEM is Schrader but of course it appears different than the new Schrader. Hopefully it works well and doesn't cause any issues. Old one lasted almost 12 years.
