MY right rear tps went out and I'm just geting XXX on the read out. The tire is fine and full of air. How much am I looking out, labor included, to have it replaced? Thanks.

 

I dunno!

And I certainly don't know why a sensor should be bad on a C6. Even the oldest 2005 C6 isn't anywhere close to the time period where sensor batteries should be running low on power. The sensors have a design life of 10 years, but I guess yours could be somehow be getting weak.

I'd be more likely to think the sensor had been damaged somehow. Have you done anything recently that would expose the sensor to being damaged - like mounting new tires???

New sensors are available from several forum vendors (Gene Culley, Bob's House of Wheels, etc.) for around $60 shipped.

Your profile shows you have a 2006, so you need a sensor with GM Part# 25758220 (or a compatible aftermarket one). Do an internet search for "25758220" and you'll find a bunch of sellers - including used ones on fleabay for around $30.

You'll have to go to a tire shop to have them break the bead to get the old sensor out and the new one in. That shouldn't cost more than $15. If they keep the tire from slipping on the wheel, no balancing should be required - just reseat the bead and set your normal tire pressure and stick it back on the car.

Then you'll need to have them perform a sensor relearn procedure to program the new sensor ID# into the TPMS computer in the car and you'll be done.

I'm not so sure about that 10 year life...I just replaced all 4 of my TPMS on my 2005. They were giving false flat warnings about once a month or so. I got tired of hearing them and replaced all four. No false alarms since then. The owner of the tire shop told me that the claim of 10 years is exaggerated. He is seeing the replacement life as averaging about 5 years. He did note that the newer TPMS (2008+) are supposed to have a longer life according to the technical reports that he is reading. Time will tell if that is true.

And before the question comes up.....the tire shop owner is a friend. He did not sell the TPMS to me. I provided the TPMS to him for installation.

Yes.....like with anything else, YMMV.

My 2005 is now owned by my brother-in-law. It was an early build '05 (Aug 2004), and the sensors are still working great.

The C5 sensors were advertised to be good for 7 years or 100,000 miles, but many owner's sensors are still working after more than 10 years.

BTW, the C6 sensors are all exactly the same for the 2005-2009 cars. Schrader didn't do anything different in the design or manufacturing process in 2008.

However, the 2010 and newer C6 uses a different sensor.

But.....that "new" sensor has been used on several other GM vehicles for several years now, so they're not really new at all, and they have the same design life as all other current Schrader sensors - 10 years.

Just to clarify....the comment from the tire shop owner regarding the newer (2008+) TPMS sensors lasting a bit longer was referring to all types of TPMS sensors...not just the GM version. At the other end of the spectrum...he showed me some very interesting BMW sensors that only lasted about 2 years on his personal vehicle.

My daughter's 2000 C5 has the original sensors, our 2002 also has the original's. I hope it will be a long time for our 2009 before it needs them....

 

I owned a 2000 C5 (purchased new) for 10 years, 2 months.

One tire sensor failed after 9 1/2 years, the other three sensors were still working when I sold the car.

 

With labor being free, then a new set of OEM sensors will run about $100. Hence if two of them have the batteries dead in them, the other two will be shortly to follow as well.

Once the new sensors are installed in the tires (get the tires re-balanced at the same time for nothing more than piece of mind if he will due such for free), the programming the new sensors into the car are a snap once you have your hands on a rest tool.

Notice the order of which you need to program each wheel back into the RCDLR once you have got the car into TPMS mode, starting with the drivers front tire first, then working around the car clockwise each tire to you end up with the drivers rear tire last for the double horn honk telling you that all 4 tire TPMS have been programmed into the car!!!!

To add, before you replace the sensor, try to reprogam then back into the car. Hence the RCDLR can glitch once in a while to forget a sensor or two, and if the sensors are still good (battery still has power in them), they should program back into the car.

Myself, I have a Cub pro-101 that I can take a quick reading of the TPMS to see if the batteries in them are still good before even putting the car into re-learn mode to program then back in.

And before you ask, yes there is a way to change out the batteries in the TPMS for about $10 total. The glitch is you need to have them out of the tires to dig the old battier out and solder new one in to start with. Hence $8 dollars for the batteries, and $2 for just new rubber grommets for the stems before you put the TPMS back in the rims.
