All TPMS Sensors Showing Dashes
I know the TPMS system has been discussed here ad nauseum and I did try several searches, but I can't find an answer to my specific question. I recently purchased an '03 AE with about 20,500 miles and soon after getting it home, the right front sensor showed dashes and the Service Tire Monitoring light came on. About a week later, all tires are showing dashes! It seems unlikely that all sensors would die at once, so could this be a receiver problem? Is this common? Is this something that I can fix with simple parts replacement?
Thanks for any help!

They're all four 12 years old, so it's possible. Very unlikely it's the receiver. Does your remote still work? Did you check the codes in the DIC?
First thing I'd do (after checking codes) is get a strong magnet and reprogram them. I'm assuming you are driving the car often. If not, first thing I'd do is take a road trip to see if they activate after a drive. They shut down when inactive to save the internal battery and reactivate after driving a while.

OK, just checked and I got codes for all 4 sensor malfunctions. Guess that's it! It just seemed strange that they would all go out in such a short period of time, but I guess that's what happened!
Thanks for the guidance.

Try the relearn but just keep trying different wheels to see if any of them work.
Also, Does the key fob work or not?
Those codes don't guarantee the sensors are bad. Like you, I too think it's highly doubtful all 4 would go dead within a week of each other.

Yep, the fobs do still work. Forgot to mention that in my first reply. Doesn't the relearn go in sequential order? First time I did it I couldn't get it to get past the RF wheel, which was the first to die.

You have to do all four at the same time. If you skip or don't finish, the program erases the others. That's probably your problem. Try starting with each one and see which one doesn't beep and that should be the bad one.

OK, I think I'm on the road to figuring this out! I reset all the DIC faults and redid the learning process. All wheels except the RF are working! I didn't know I had to clear the codes before I could do the relearning setup. So, I guess it's just the RF sensor that's bad, which is where I was last week. Thanks so much for everyone's advice and patience with a Vette newbie!
