I put new rims on my C5 and had the sensors transferred over and it seems like one of them won't take the magnet test? Is there batteries on these units or should I get all new? Also how can I turn off the sensors so the vette doesn't keep popping up warnings? I can install new when I get new tires.

I just put a set of these on my 2000 and they programmed just fine. The magnet works best if placed on the rim between the spokes, not around the stem of the TPS.


This is not an endorsement. You might find them cheaper. they are Regitar TX5028 for 97-00

Thanx. I tried all over the sensor with 2 different magnets but still no luck

I am in the middle of doing new tires right now and bought all new sensors. Once they are about 10 years old it is only a matter of time. I have had an issue on my Malibu where it is now losing a sensor once in a while, likely due to batteries teetering on the edge. I had the dealer look at it and they used a Tech II and got it to recognize the sensor immediately. It was short lived and the code came up again a day or two later. Since then I am living with the codes coming up until I put new tires on the Malibu.

If the batteries are low then you may not be able to program it. Not sure how to shut the system off. Best deal I could find on the genuine GM sensors was Rock Auto.

Yes there are lithium batteries in the sensors with an expected life of 8-10 years depending on use. If the sensor was working before they transferred it to the new rims it could have been damaged. If you were able to program the other three sensors with the magnet you're using, it was either damaged or the battery is dead.

There is a date code on the OEM sensors. It looks like a clock face molded into the plastic case. The arrow points to the month of manufacture and the two numbers in the center on either side of the arrow are the year. If you get new OEM sensors always check the date code to be sure you are getting new stock.

You can program the sensors before you mount them and mark the wheel they need to go in on each one.

No easy way to to program out the tire sensors. You need a Tech 2 scan tool and depending on the year of your car you may or may not be able to program out that option.

thanx for the info

My car is 17 years old, 116,000 miles and I have only had to replace one sensor. The batteries on the other 3 are still working fine- Pretty good quality I'd say!

Its like headlights...don't just replace one...if one tpm is dead the others are not too far behind...just get the GM TPMs and be sure to check the date...at first I got mine from the dealership and they were 4 years old and I said no way so they got me a fresh date...MFkers ...
don't be thrifty and buy crappy TPMs...new GMs will last about 10 years...

Wow....keep replacing one at a time if you are bored with nothing else to do ......dang bankers...all you do is think about money

I have done a bunch of them on several cars. I never had a problem with using the magnets to train them. Until I ran across one set that I could not get to train. I had done it enough times that I knew how it should work, but it just didn't. The sensors were brand new and a recent date, but I could only get the left front and the right rear to train about a third of the tries.

I got frustrated and bought a new magnet. I bought the strongest I could find. I got a 1" x 2" x 3/8" neodymium N52 magnet. It worked the first time on all four sensors.

Since I had done it so many times I wondered why people were having problems until I ran into the problem. I knew I was doing it correctly, but it just didn't work until I got a strong magnet.

I agree. Many people report problems on here about off brand sensors not being able to train or not work right.

The one exception to buying the GM sensors is Schrader. Schrader made the OEM sensors and they are exactly the same except the plastic body of the sensor is orange instead of black. Sometimes the Schrader TPMS are priced better.

8 to 10 years is commonly stated as the life for the batteries, however many people get longer than that. I think some of it is based on the car usage since they go into a power saving mode when stationary for a while. I had about 14 years on mine when the first one failed. Some people report even more than that.


Good luck.

Aug 2000 delivery date, 116k miles.
Right front is out - the other 3 are still working fine.

Mine is 1998 (not sure delivery date), has just 10,500miles and I replaced one sensor maybe 9-10 years ago and right now Im not for sure if need to replace another one bacause the DIC shows something like: (Check Tires sensor system rear right), the thing is that the one I replaced a few years ago, I took off the battery and Im sure that is only to replace it, BUT, I cant remember the polarity of + and -

What Greg_E mentions is some good advice.

New tires, new sensors. Works for me.

If you want to replacee batteries on these sensors yourself , these videos shows how to ( 4 videos) :

Anything like that for later C5s?
