Uh-oh!! Expert????? I don't know 'bout dat, but I have been dealing with these things on the C6 for a couple of years now. I have an early '05 and ran through my first set of tires by about May '05. I got good deal on a set of wheels/tires/sensors another forum member had taken off a new car for aftermarket wheels and that's when I ran into the sensor problem.
I was going on a road trip in 2 days, jacked the car up and swapped my old wheels for my new wheels that already had the tires and sensors mounted, and thought I'd just take it by the dealer and they'd do the 2 minute relearn. Well.....they said bring it back the next day, sit in the service line for however long until they got to me, pay them 10 bucks, and they'd do it. I didn't have time to do that.
I went to another local dealer and was told the same thing, except that it would cost $49.95 for the 2 minute job.
I went on the 1,000 mile trip without resetting the sensors and had DIC messages and warnings numerous times. It never caused a problem because I didn't need to turn off AH, but with the stiff sidewall runflats you just can't tell if you get a flat like you can when a normal tire loses air while driving - so I was checking my tire pressures all the time with my pressure gauge and came to appreciate having the DIC display of pressure and the warning if you lose pressure.
I got back from the trip and started learning about the sensors and the TPMS. I got a tool from eBay not even knowing if it would work on the C6. It did, and I reported about it on the forum. A number of other forum members asked if I got any other tools to let them know. I told several about eBay auctions going on, but most of the time they told me "I don't do eBay, so can you get it for me?"
That started me getting tools whenever I saw good deals, so I could pass them on to other forum members at cost + shipping. A lot of guys don't know what tools are available, how much they should cost, if they will work on a C6 (or your other vehicles), and they don't like doing the bidding thing or PayPal on eBay.
Whew......All that said, the Bartec Trackside rays06c6 mentions in post# 2 above from Wright Tool for $140 (about $150 with shipping) is the best price I know of. That tool is designed to only work on the C6, or probably any other vehicle whose sensors are triggered by a simple continuous wave transmission from the tool.
There are many sensors out there used on all the different makes/models of vehicles, and every 4 wheeled vehicle under 10,000 lbs. will have to have sensors and a TPMS starting this month (2008 model year) by federal law.
Because there are so many different sensors, many require a sort of morse code pulsed transmission (instead of the continuous wave required by the C6) from the tool to trigger them during a relearn procedure.
If you want a tool that you can use on your other vehicles, you may want to spend an extra 70 bucks (at least for a couple tools I've got available, and a couple hundred more from most sources) and get something that can trigger your other vehicle's sensors when you rotate your wife's tires, for instance. Some sensors (I think Jeep/Chrysler) still only require a magnet (except, possibly, the Viper). I think Toyotas may need a Toyota tool something like a GM Tech 2. And some reset themselves automatically.
Take a look at:
http://ktipst.com
http://www.ateq.com/T.P.M.S/ATEQ_Pro...vice-cent.html
http://bartecusa.com/products.html
All of those tools are completely universal - designed to work with all sensors that require a radio transmission to trigger/excite them for diagnostics or for resetting the TPMS (the "relearn" procedure after a wheel swap or new sensors are installed).
The KTi, or the identical TIPS tool, can be upgraded as new sensors with new triggering protocols come out, but it needs a PIM (Programming Interface Module - about $180) and a $49.95 per year subscription (1st year is free) to upgrade the software. These are available on eBay for $300 and up (actually there's a very good deal on a tool plus a PIM for about $310 right now on eBay). I have a couple of PIMs and can do a package like that for $300.
The Bartec Tech 300 is the 2nd tool listed on that Bartec websit above (the 1st tool is the $150 Trackside you can get from Wright Tool). The Tech 300 is a much more capable tool and can be upgraded for free. It doesn't have a screen, like the ATEQ, but you can hook it up to your computer and see some info from your sensors - ID#, battery strength, and there are fields for tire pressure and temperature but I haven't ever gotten a readout for those. The Bartec Tech 300 can usually be found on eBay for around $300.
I don't know much about the ATEQ except that I have had several VT50 tools and it works great on the C6 and is apparently upgradeable, but I don't know how. The really neat thing is the screen that shows you sensor ID# and tire pressure. You can get a very accurate readout of tire pressure to the nearst 0.2 psi without even taking your valve stem caps off.
I've got a couple KTi/TIPS tools, an ATEQ VT50, and a Schrader 21210 (Schrader makes our sensors, and this tool is exactly like the Bartec 300 except it has Schrader markings on the front). All these tools are available for $220 shipped ($300 for a KTi plus PIM and a holster).
The official GM tool is the Kent-Moore J-46079. Do a search on eBay for "46079" and you'll find one listed. GM Techs usually snap these up on eBay because they can get them cheaper then from their tool supplier, but if you really want the official GM tool be ready to pay well in excess of 300 bucks - but maybe you'll get lucky!!!
Well.....that was a lot of info, but I hope it helped you figure out what you might want/need in the way of a tool.
BTW, all of the C6 models and model years use a dark gray "peanut" shaped sensor with GM Part# 25758220 (at least all U.S. and Canada cars - cars built with European specs need a different one). If you're getting a set of new sensors for a second set of wheels, you also need the retaining nut. Forum vendors sell 4 sensors and nuts for about $220. A set of used sensors will probably have the nuts and have been going for around $150 for a set of 4. If you're remounting used sensors, take a good look at the rubber grommet at the base of the valve stem and replace if at all concerned - Schrader and GM say replace them, but I've remounted a couple sets with the old grommets with no problems.
Questions, give me a holler!
