[C5] TPMS

[2Vettes]

The rear tires are reading xxx on the dash. There has been no work done on the wheels/tires. I read how to reset the computer but I don't know where to buy the round magnet with the hole that fits over the valve stem.
Can someone please tell me where to look?
If all else fails I'll take it to the shop but I wanted to do this myself.
Thanks in advance!

Here's a magnet for you -> http://www.ebay.com/itm/OTC-3833-4-T...041#vi-content

But if you know the diameter of the hole you need for the magnet to fit over the valve stem, one of these might be cheaper.

This video shows the procedure. Looks pretty easy to do...

Any relatively strong magnet will work. I use one out of an old stero speaker.

So, does the magnet have to be round like the one in the video?

Never done it myself, but I've heard that any magnet that is strong enough to trigger the reed switch inside the sensor will work.

Many of the newer rare earth based magnets should be plenty strong enough. I've got some small, less than dime sized, magnets that are incredibly strong for their size. If you put two of them together you have a devil of a time separating them.

So you can try any magnet, I guess, and if it doesn't work, then you simply have to find a stronger magnet.

Of course, you COULD go all out and get something like this......

Which is probably severe overkill...........

Most TPMS only last 7 years.

Hey Linda,

Nice to hear from you. Typically when the dash reads xxx for one of the tire pressures, your tire pressure sensor has gone bad. I had to replace them on our Navy Blue '01 a couple years ago. I also installed them on my Z06 when I got it. I purchased the sensors from GM Parts House because they were reasonably priced and the shipping took place very quickly. I had Estero Bay Chevrolet replace the units after they arrived and I have not looked back since. The sensors run around $40 a piece for your year Vette. But if the rears have gone, the fronts are not too far behind them. Just replace all four.

Here is a link to the parts, the guys are easy to deal with by phone. Good luck.

I'll second what Rich said about GMPartsHouse. Gene has done right by me, every
time I've ordered anything from him.

Well, here's a question for you guys. Are these things fixable? I'm guessing it's just a battery of some sort in the sensor that depletes over time.

Reason I ask is because if these sensors are specific to the C5 model, then certainly GM is going to stop providing them. If there is no aftermarket source, then what?

I seem to recall reading somewhere that people were having trouble finding C4 tire pressure sensors, but I can't recall when or where I read that.
