I think the sensors are dead, while doing my errands today, I set the DIC to tire pressures and the display where it should say the pressure was blank,

 

That is correct. If you want to know tire pressure when stopped you need to do it manually with a tire gauge.

The sensors arm at the speed of 15 mph. If the vehicle is stopped for 1 minute then they go into sleep mode again.

If the batteries were dead it should show XXXX.

Is it possible you have an export model that does not have remote features? If you have a Z06 they did not come with sensors.

 

it's a base CA model and I think it should have them,
i was doing 70 on the freeway and all it said was

"Front Pressure Lft _____ RT ______"
"Rear Pressure Lft _____ RT ______"

looks like it wants the readings, but their just blank.

 

Try doing a new tire sensor learn and see if you can.


Reprogramming the Tire Pressure Monitors

1) Turn ignition on.

2) Press "Reset" button in order to clear any IPC display warning messages.

3) Press and release the "Options" button on the DIC to scroll through the display options until the IPC display is blank.

4) Press and hold the DIC "Reset" button for 3 seconds.

5) Press the "Options" button again until TIRE TRAINING message appears.

6) Press "Reset" button until the IPC "Learn L Front Tire" message appears in order to begin the programming.

7) Install the J41760 Tire Pressure Monitor (TPM) System Programming Tool (large magnet will do) over the left front valve stem.

8) The horn will sound, indicating the left front TPM sensor is programmed (if this takes more than 15 seconds, pull magnet back and try again). You will have three chances before you must start the entire process over.

9) When the horn sounds, proceed to program the next TPM sensor in the following order as directed by the IPC messages: -Learn R Front Tire -Learn R Rear Tire -Learn L Rear Tire Programming can be canceled by turning ignition off, waiting 2 minutes with no sensors being learned, finishing all 4 wheels or through the DIC. If the programming is canceled with less than 4 sensors learned, it will only accept the codes programmed up to that point.

 

I finally remembered to do this, i used a round speaker magnet, and nothing happen, it just timed out every time I tried.
Time for new valves.

 

I've got the EXACT same problem with my '03...driver's side for me as well.

Temporary fix was to get some Permatex defogger adhesive (electrically conductive) from AutoZone. Comes in a small single use pack for around $14 - $15 if I remember correctly. I stripped the wire back and then glued the crap out of it on top if the tab that is still on the window.

It hasn't broken free yet, and the defogger seems to work OK. If it ever does break off then I'm at a loss as to what to do about it myself. Might as well forget trying to solder another complete wiring assembly on the window as it acts as a huge heat sink...ask me how I know...

But - maybe the old clip could be carefully taken off with a razor blade and have another one put on with the same adhesive? That would be great if possible...but I've never seen where I could get that wiring "assembly".

 

Could be dead sensors, or maybe the PO removed the TPM sensors.
