I changed out tires wheels and installed new OEM sensors-- didn't need to do anything-- they picked right up and started working.

 

Negatory!!!

When you put in a new set of sensors, nothing automatic happens to automatically program them into the TPMS memory.

The TPMS "remembers" the last known tire pressures so when you start up the car and start driving you don't get alerts during the first couple minutes of driving until the sensors wake up when you go faster than 20 mph and they transmit your current pressures.

In your case with your new sensors not programmed in, the TPMS is remembering the old pressures last reported by your old sensors, and that's what you see displayed in the DIC.

You could do a couple things to confirm that your new sensors are not programmed in:

• Disconnect the battery and the TPMS will lose those last known pressures and the DIC will show "xx psi" all around. If the sensors are programmed in, when you start driving faster than 20 and the sensors wake up, after a couple minutes the DIC will get the updated pressures and display them properly. If the sensors are not programmed in you'll never get updated pressures - the DIC will stay at "xx psi"
  
  
• Put air in or let air out of a couple tires and note the pressures your handheld gauge shows. Go out and drive the car faster than 20 mph for a few minutes and if the sensors are programmed in the DIC will show the correct pressure and be about the same as your handheld gauge showed. If the sensors aren't programmed in the pressures in the DIC won't change
  
  
• Just go out and drive the car for 20 or 30 minutes. If the sensors are programmed in the pressures in the DIC will increase as the tires heat up. If the sensors are not programmed properly the DIC pressures won't increase

The sensors DO NOT program themselves in automatically. If they did, every time you parked next to another Vette the pressures in the other car's tires could be displayed on your DIC.

You must do the relearn procedure to program your new sensors or they won't be recognized any more than any sensor in any other car you park next to or drive near when going down the highway.

BTW, did you keep your old wheels/tires/sensors???

If so, and they're in your garage, and those old sensors are the ones that are programmed into your TPMS memory, those old sensors will update the TPMS when you park withi 40 or 50 feet of them. That way it may appear that your pressures are normal, but you could actually have a flat tire because the pressures are your old tires, not your new ones on the car.

So.....it's important that you get the sensors in the wheels on your car programmed in properly using a TPMS tool.

Thanks for the info

My dealer told me unless I got a warning displayed from the DIC- They are working. My car is about 20 minutes from the dealer- drove it twice since for about 20 minutes a clip-- no warnings yet

Will try the let air out / in scenario today when I get off work , very interested to find out what happens

Old tires and wheels with sensors are out back in shed 250ft away

Thanks again

Hey K

I looked in your profile, but only kinda sketchy info in there. I did find out that you don't like Gators!!!

But, I think you have a 2006, which will take about 1 hour of continuous driving (without shutting off the ignition) before you get a "Service Tire Monitor" DIC message.

The 2007-2008 is about 30 minutes, and the 2009 and newer takes about 20 minutes until you get that message.

So....for a 2006 you won't see any indication of a problem until you drive for approximately 60 minutes on one ignition cycle.

I don't know how far the sensors will transmit. I've tried it out to 85 feet and the TPMS in the car picked up the transmission from a sensor at that distance, but I quit at that distance, so it may be much farther - so I don't know whether it will pick up your old sensors 250 feet away or not. But your TPMS will remember the last known pressures anyway, unless you disconnect the car's battery.

If a dealership did the new wheels/tires/sensors for you I'm sure they must have programmed the new ones in.

Let us know what you find out!!

Bob

 

I just got new wheels & need to get this damn tool so this is not good to hear. Anywhere else that I can get it shipped today?

 

I just ordered a reset tool yesterday from Tire Rack. It was shipped from Delaware and will be delivered today. I ordered a model from Cub for $59.99, but they had other brands/models at various prices that were in stock also. I think if you call them soon enough you can get one delivered by tomorrow (if shipped from the Delaware wharehouse).

Bob

Thanks for all the input

It is an '06 base coupe

its raining out and will be a while before I get a chance to drive it for an hour-- but I will let you know when I get it out

Once again-- thanks for the input

 

Here's one for $62.33:

You can see that it says "call to order", so you can't order it online.

Click on the "How To Order" link at the top of that page and you'll see their phone #.

How fast they can ship it, I dunno!?!?

Bob

 

Bob's right. Same as my 05 Vette my 2012 GMC Acadia Denali and Denali HD truck still have to be reprogrammed every time I switch wheels around. Could be self programming may be in the future but who knows.

 

They ship pretty quick, mine made it in about a week if I recall. Even though it said 'call to order', the guy on the phone said it could still be done online, plus I tried it before I called at the time for grins & it looked like it would have went through. I called anyways after that because it said 'call to order'. Plus, by calling you can see if they are in stock or on backorder. Not too long ago on another forum, people mentioned that they had to wait as they were out of stock. Now that all the newer cars need some sort of tool like this, they are in high demand.

 

BTW, anybody reading that has a 2010 or a 2011 that was built before January 2011 (and some other GM vehicles) the tire pressure sensors can be triggered by changing air pressure in the tires - you don't need a TPMS tool.

That only applies if you have your original factory installed sensors - which are a green sensor, part# 15268606.

Starting in Jan 2011 they changed to a different sensor (black in color) that can only be triggered by a TPMS tool.

The 2005-2009 uses one model sensor (gray in color), and the 2010 and newer have a different TPMS that will recognize either the green or the black sensor.

Bob

 

After I posted I saw the Tirerack.com tool. I ordered it & it will be here tomorrow.

 

OK Bob:

Took the car out on a trip this past weekend-- sho-nuff , 45 minutes in got the alarm.

Went to the dealer this morning and they reset it. The guy said lots of them reset on their own-- hard for me to believe that now!!!!

Thanks

K

 

I went that route too. The ATEQ VT15 I think it is....Mine showed up in two days. Works great.

 

I bought one of these:

http://www.tirerack.com/accessories/...toring+Systems

Worked fine, BUT it took a couple attempts for it to finally register. I think that had to do with the older TPMS in the wheels I was running than the tool, though.

 

Do you know the color/part # of the early 2005 sensor?

 

Of course!!!

I had an early 2005 (built in Aug 2004). The car is now owned by my brother-in-law, and the sensors are still working great!!

You will only have these sensors as OE if your car was built in about Sept 2004 or earlier.

The part# on my b-in-law's sensors is 10354988, and they are square and black, rather than the peanut shape of the current sensors. Here are some pics I took when I owned the car. You might be able to make out that part# molded into the case:










These sensors were also used on the 2005 XLR, and I believe the 2004 XLR had a different (but compatible) sensor with part# 10306573. I believe that sensor was also square and either black or gray.

If you put both of those part#'s into a GM parts site you'll see that they both come up as superseded by the current 2005-2009 C6 sensor: 25758220 - the gray peanut shaped sensor.

Here's a video I made several years ago when I still owned the 2005, and I trigger the sensors with both a magnet and a tool:




Occasionally I see some of those sensors on eBay, but they're getting pretty old and have only a short battery life remaining.

Bob:

Super video!!

I have the sensors that look like the other ones on the concrete next to the black ones(grey)-- can I reset them with my FOB and a magnet like the black ones??

Thanks

K

 

Hi K

If yours look like this:




Then you have the OE sensors for a 2005-2009. You might be able to make out the GM part# 25758220 molded into the case.

The 2010 and 2011 built in Dec 2010 or prior have that same peanut shape, but they're green.

Starting in Jan 2011 C6's came from the factory with a peanut shaped black sensor.

The gray and black ones require a radio frequency transmission from a TPMS tool to trigger them.

The green ones could be triggered by a tool or by changing air pressure.

Only those very early square black sensors could be triggered with a magnet. All C5 sensors are triggered with a magnet as well.

So.....if you have the gray sensors you need a TPMS tool in order to trigger them to send out their data during the relearn/programming procedure.

Bob

 

Yep-- I have the grey ones-- OH well--

Thanks
