Sensor HELP!!
Hey everyone! I hope someone here can help me out. I finally got my new wheels/ tires/ and sensors mounted today on my 2000 C5 Vert. I got all 18" black Cray Scorpions, with tire sizes 265/35/18 (front) and 295/35/18 (rear). The sensors are brand new from Gene Culley, and they are the correct style (97-00). The tire shop said that they programmed the sensors but I was not getting any readings, but I was also not getting any codes, The readings just showed blank. I got my first codes on my third and longest trip home. When I got home, I followed the instructions to reprogram them with a strong magnet (and I mean very strong earth magnet) and the fronts both program fine, but the right rear does not seem to want to program at all. I tried it about 6 times and the same story each time. Any suggestions on what I can try next?
I did have the tires filled with dry nitrogen instead of compressed air. Does that matter?
Thanks in advance for your help.

There is a possibility that the sensor that will not read was damaged during the install. Try moving the left rear tire over to the right side temporarily to see if it will program - if so, I'd say the sensor other sensor is bad.

but you don't have to move the tire. Just go straight to the left rear intead of the right rear while programming and if it works the car will think the LR is the RR.No matter what, if all train properly with the exception of the right rear I'd pull that sensor for inspection. But before I would send it back as faulty I would try to train it while it's in my hand with a good magnet to see if it will work at all. If you can't train it with a magnet directly on it then it's definitely got something wrong with it...assuming there's no obvious damage from the install. Just another opinion

With due respect to the vendor; sometimes "they" (& us) get stuck with NOS. Batteries may be dead from sitting on the shelf to long. If so I'm sure the supplier will replace it for you. BTW, they each have their own barcode ID number.

".....filled with dry nitrogen"
You are kidding - right?
This is another myth (better than air) that continues to amaze me.

***Post Update***
***UPDATE*** On my way in to work this morning the rear wheel pressure display changed from "blank" (no reading) to "XXX" on both rear wheels. The fronts are displaying just fine. Does this mean the rears are possibly working or transmitting now, but not programmed? 
Also, as far as filling the tires with dry nitrogen, they offered it to me for free. They also offered to refill them up for free for the life of the tires, and told me that if I needed "regular" air while I was out somewhere to go ahead and fill it and then bring it back in for them to redo the nitrogen. I figured that freebies rarely happens to us Vette owners, so how could I turn it down? I figured that if I don't see a benefit I will switch back to regular old compressed air.
I will try the suggestion to program the LR as the RR and see if it works.
Thanks everyone for the feedback. Please keep it coming.

Tire monitors can and are easily damaged when installed incorrectly..it has happened to me and is a pita ....what you are describing is a bad TPM, when it is removed you probably see a crack where the epoxy meets the black plastic nearest the schrader valve. By the way expected battery life is around seven years.

I think your system just finally got around to telling you that the sensors are not working. Before I rebuilt my sensors, I ran the car without the sensors and my display was blank. After a short while, they all went to "XXX" just like yours did. But I agree with Cajun99, remove the sensors and train them again with the sensors in your hand. You have something like 45 seconds to train the sensor before the system times out. Hold the magnet steady to the sensor's sealed side, to one side of the valve stem. If the horn doesn't sound after 10 seconds, move the magnet over to the other side of the valve stem and hold it there for another 10 seconds. If it doesn't train that way, then it is bad. I hope this helps....

So I got an interesting call from my tire shop this afternoon stating that they needed me to bring my car in to double check my sensor installation. Of course I told them about the issues I had been experiencing from the time I picked it up though my current woes with my rears only. Hopefully they will get it figured out. I hope that the sensor is not broken. It just seems like a PITA to remove them, reprogram them and reinstall. But I will insist that they use the "pre-program" method prior to putting them back in my wheels.
