I will be replacing the tires on my 2013 GS. I have no issues at this time, but was wondering if it would be a good idea to replace the sensors? The tires are original so I know it hasn't been done yet.

Thanks for the help, Don

Original sensors?

DonRMac

Yes. The car has only 16,000 miles on it.

Figure that the tpms should be good until at least 2020.


If you get 00 readings for the TPMS's in the DIC, then chances they just need to be reset to car and the batteries are still good in the TPMS's.

When the batteries in the TPMS go bad, then you will get XX reading for that sensor in the DIC (even after trying to reset it).

For what it is worth: Mine's a 2007 Z06, 44,000 miles. TPMS are fine.

My 05 60,000 miles still has the original rear sensors, last year replaced the front, when one tire was giving me XXX pressure, decided to do both sensors.
If you like to spend money, go ahead, be my guest.

If they aren't broke, I wouldn't fix them.

Original sensors in my 144K mile '08. I have one getting weaker that has an occasional communication issue, so maybe I'll swap them out on the next tire change.

With only 16K miles on the OP's car, I'd be happy to accept his old ones.

Original sensors still in my 2007.

Go to the tire shop and if they have the right tool they can check them and let you know if the battery is good, bad or where they are. I have a 2011 GS with 22K on it and just replaced the rear tires and he scanned them and said they are good.

yep, I agree, have the sensor battery checked if you are worried, because most TPMS issues are caused my cell phone or charger interfere. My 2011 is still on originals, 5 sets of daily and track driving tire sets later

Thanks for the replies guys. I appreciate all the feedback.

Cheers! Don

Those sensors are pretty robust, and are generally thought to be "life of the car" items.

The rubber seals where the sensors mount on the wheel, and the valve core in the stem, however, should be replaced every time the tires are replaced.

If you buy your own parts, you can usually find "TPMS Sensor Service Kits" on Amazon or RockAuto.com for a buck or two each. A really good tire shop will stock the parts and recommend replacement. Most national chains, and most local tire places don't know to replace those parts.

The owner of the C6 I've been driving/supporting just got new tires (third set for this car at least), and I think the TPMS sensor have never been serviced. The shop she went to to get the tires put on neglected to do that part of the job. One valve core leaks sometimes after you put air in. You have to "jiggle" it to get it to fully seal.

I plan to replace all the cores myself, and if that resolves all the issues, I'll let the seals at the wheel holes go until the next set of tires.

I really don't want her to have to take it to the shop I actually recommended, and have them remove the tires from the wheels, properly service the TPMS sensors and remount the tires.

Hey man this is pretty much a copy and paste on another thread where I answered the same question I have links to the sensors and batteries should you choose to replace them. I wouldn't replace them unless you have to. Again, this is a copy and paste from another thread I replied to so some of the stuff in there might not make sense because I kinda diagnosed the problem but your answer should be here best of luck brother!
The trick to this is keeping an eye on the problem for a day or two to see if the reading changes (which in your case it did). The two most likely culprits are either bad sensor(s) or the batteries going bad on them. When a sensor goes bad you will see "XX" on the display and it won't change at all which isn't your case. When a battery starts to go out the signal becomes weaker and sometimes doesn't reach the computer just like with any dying battery. If I were you I would try replacing the batteries first as it is a relatively easy DIY project. The battery is the same diameter as the C5 batteries but are thinner in our models. The model number is RENATA CR2450N. It is a 3volt lithium battery. This link SHOULD work: http://www.renata.com/pdf/3vlithium/DBCR2450N.04.pdf. There is also a thread here that shows you how to replace them found here: https://www.corvetteforum.com/forums...-tutorial.html should the batteries now work then (which I doubt) then I'd personally buy the sensors because the price for the dealership to tell you the problem alone will be expensive. You have to be very careful when buying the sensors as changed from early in the C6 production years to the later years. The OEM GM supplied sensors for a 2005-2009 C6 are GM Part# 25758220 and black in color. The OEM GM supplied sensors for a 2010 or newer C6 are GM Part# 15268606 and are green in color. You can Google them and find different brands I personally went with AC Delco. I would post a link to them but I'll leave deciding the brand/price up to you. I will also say that if the signal were interrupted it could cause the same symptoms you saw but that is very unlikely. I do know of cheap car chargers or magnets in the car causing that issue so keep that in mind if those apply to you. I'll also add that Walmart charged me just $10 to replace the sensor. To program it just put the car in accessory mode where the little orange light on the engine start button is on and press the lock and unlock button simultaneously until you hear a honk from there the person programming it should know what to do. Best of luck brother!

Thanks Racer X. Good to know about the seals. I'll ask the tire place about them before I have the tires mounted.

Most good tire shops can change tires without disturbing the sensors. Some, including Discount Tire, will try to sell you what they call a sensor rebuild at $20 per tire. Their "rebuild" consists of a new O-ring and a new nut. Although, I've seen tire guys re-using the nut.
My Vette is on the 5th set of tires (145K miles) and the wife's Caddy (exact same sensors) on the 3rd set (100K miles) have never had the sensors changed, moved, rebuilt, etc.
If you remove the nut and don't properly clean the sensor stem and both the inside and outside of the wheel, you run the chance of a future leak.
This is a case of "If it's not broke, don't fix it."

DonRMac

Gotcha.

Same here!

Until yesterday when I replaced the 11-year old OEM tires and TPMS sensors on my '06 Z06, the sensors were still working fine but I replaced them anyway (at the advice of the Corvette Tech) since I didn't want to have the tire(s) broken down again sometime in the near future just to replace and relearn a new set of sensors. Your call.

I installed my 4th set of tires at 86K miles on my 2006. All 4 of my sensors were still working fine, but since I use non runflats, I decided to replace all 4 with new sensors. I got a great deal on them at $29.00 a piece shipped.
I'll keep the old sensors, and maybe when I'm bored, I'll dig out the old batteries from the sensor body, put new ones in and use those sensors in 10 years time
