My 2000 coupe needs new tire press sensors. From what I have gathered so far, I need a sensor that:
1. Uses ASK mode data transmission
2. Uses clamp-in mounting?? Still have orig factory wheels that have always had a slow leak on rears with 3 different sets of tires so far. (Prefer metal valve stem as opposed to rubber but if the pop-in rubber type seals better, will likely go that route)
3. Needs a 100khz signal to trigger sensor to transmit data
4. Transmits data on 315mhz
5. Comes "pre-programmed" Not sure if this means that it's capable of ASK and FSK modulation but will be pre-set to ASK mode on 315mhz??
Appears the magnet method to trigger sensor is no longer used. If I do find a magnetic type sensor, it's likely to be very old and batt is likely abt gone.
Looks like I will need a 100khz transmitter from Amazon (~$8) for relearn.
My suggestion would be to go to the Schrader web page, look up your car, and purchase what they suggest. Schrader is the OE supplier, so whatever they recommend, will function properly. The main reason I suggest their applications page, is because over the years, their part numbers have been superseded by new numbers, and you want to obtain the newest (and freshest) parts. They also sell (at least they used to sell) the proper magnet that triggers the sensors.
The smaller magnet, next to the Schrader magnet, is a Stanley Tools magnet, that I bought at a hardware store. I was the first magnet I used to program my sensors. It worked sort of OK..........
I read that "Everything TPMS" thread. That's where I learned abt the freq's, modulation modes and was steered towards the Moresensor brand.
The ASK VS FSK modulation was what I was hung-up on. Pretty much none of the sensors I found even mentioned it.
Also learned in the process, that the pop-in version is speed rated to ~115 MPH. Clamp-on limit is 155 MPH. Not that I ever go that fast, but someone else might.
Ordered the Schrader 29178's from the rock. $100 delivered.. Not too bad at all..
Will order the $8 learning tool off the big A since I'm planning on taking the wheels in "loose". I'll definitely be testing them first..
I bought the programmer tool direct linked in that thread from the BIG A and the car did not respond to it what so ever. Of course it was past the return window to send it back. Thankfully it was cheap.
Busted out the mechanics magnet on a stick and NOTHING.
Then busted out the welding triangle and perfect success was had.
This will be the third set of sensors for this car. Prev versions were all "learned" with a big magnet. I keep seeing posts where they report the same thing you are. Confusing for sure. Guess I'll find out next week..

Good point. Apologize for the confusion.
I am using Schrader 28006s which are becoming harder and harder to find.
If I had to do it all over again I would try the 29178s.
I believe the Schrader 28006's are the same as the ones I ordered from Amazon in May of 2021 (GM# 25981210). (Don't remember them being $100 each at the time)
Didn't even get 4 years out of one of them. The other 3 are still working OK but one is slow to report. The dead one was slow to report before it quit completely so I'm thinking it's on it's way out. May have been old stock. Didn't know how to read the date code at the time.
