TPMS Sensor Training Concern
I recently bought a new set of Schrader sensors (#28006) from Tire Rack for my '98 Corvette.
I then wanted to check them out prior to installing, by attempting to train them, in place of current ones installed.
Was wasn't able to get any of the four to respond to the magnet I was using, yet the that same magnet works
with the current installed sensors.
Is there a problem with attempting to train with already installed sensors?
Is my magnet not strong enough for these newer redesigned sensors?
Is there a problem with my new sensors?
How do I very my sensors function prior to installing?
Thanks for any guidance or suggestions.

Are you sure you have the correct sensors for your car? The newer 2001-04 sensor's frequency won't work with a 98 (or any year prior to 01)
Looks like the 28006 is supposed to work with 98. When you enter the programming mode and hold the magnet near one, do you get any horn beep? Make sure you move the other three away from the magnet when you're programming one. Do the remote fobs still work?

#28006 appears to be the correct Shrader TPMS sensor for your '98.
By any chance, was the RF receiver in the car ever updated with the newer type
2001-2004 RF receiver?

No horn beep with any of the new ones. After many attemps with different locations (at the wheels and back by the receiver in the left rear) I finished by retraining the original installed ones. The car has not been updated with the 2001-2004 RF receiver.

Sensors
I have the 28006s. They have the following information on a label stuck on the actual sensor, that MAY help you determine if you have the correct ones:
328006 DC
315FM 63psi
ASIC No. 02073923
FCC ID:MRXGMG2R3FM
IC: 2546A-GMG2R3FM
MODEL: GMG2R3FM
Hope this helps.
You could also pick up one of these Schrader TPMS magnets. Worked for me:

I'm using a very strong disk magnet (1/2" dia x 1/4") that is also stuck to a magnet out of a hard drive. You need pliers to remove it from any metal objects. I've used it successfully in training the set of sensors I have installed now. It currently works on the ones installed on the car.
I'll check on the label info on the sensors this evening.
Maybe Bill Curlee can advise.
Thanks.

This is the 3rd or 4th thread I've seen in the past few weeks about people having issues training their 97-00 replacement sensors.
I'm wondering if there may have been some kind of batch error with the manufacturer?

I had a very similar issue with my '99 when I replaced the TPMS sensors with OE Wheels TPMS sensors. I used a hard drive magnet, then used the stealership TPMS tool only to settle for the old GM round magnet used back in the late 90s and it worked like a champ.
The vette tech went to his old faithful immediately when one of the other techs had tried for about 20 minutes using the standard electronic TPMS training tool. It was really amazing on how it worked the first time out. I even had him do it again because I thought it was a fluke. Yep, I was dumbfounded after trying so many flippin times. You might want to see if your local stealership has one. At one time, you could order them online. I really thought it was BS so never bought one, but I guess I was wrong. I would honestly give it another try with the GM round magnet if you can find one. Hope it helps brother, know exactly how you feel.

I found you need a really strong magnet to get new TPMS sensors to be recognized. I used an Engine Block/Oil Pan Heater Magnet that holds itself on the Engine Block/Oil Pan for subzero temperatures. It is very strong (Big Friggin Magnet) and hard to remove once it clamps onto ferrous metal. Placing that magnet at the valve stem works first time,every time. But I used stock GM replacement sensors on my 2000 vert, not the aftermarket sensors.

1) 02073009, 2) 02070507, 3) 02070232, 4) 02073890
Also here's the bar code numbers:
1) 5594575009023, 2) 55942330008784, 3) 55942330008144, 4) 55945750007453
And the mold date code on the body:
1) "J" 2/12, 2) "P" 7/11, 3) "L" 7/11, 4) "K" 2/12

Maybe the ASIC code is a unique number to each individual sensor-don't know. I would still try one of the "donut" type magnets. It gets closer to the rim and sensor. Additionally, when I bought a set of C5 Corvette System BBS LM wheels, it CAME with a BBS manufactured learning tool that is essentially two magnets and a fixture, that when assembled is a sort of "U" and the magnets can be placed directly on the rim on either side of the valve stem. Maybe it's just a proximety thing???

BBS LMs
Got the wheels from a member here who had bought them from someone else. Came with the tool and a brochure on the C5 BBS LM "System". Figured it was some sort of package deal they sold at one time?? Looked for a year and a half to find a set and got LUCKY. They're perfect, and back in the day, they were $1000/each wheels. No longer made by BBS Japan (all LMs are made there). Braselton had one front left in stock, and they wanted $800 after a hefty discount. Paid $1700 for the set-again LUCKY.

There's a place in PA, that an old racer buddy of mine found, that is a PROFESSIONAL wheel remanufacturer. Checked with them while I was looking for a set, and they charged like $150-200/wheel to disassemble them, check runout, and refinish them to "as new" with the correct BBS urethane finishes and clearcoats. My friend has had them do several sets of LMs (he's partial to them), including the set on his E55 MB. PM me if you need the information on the shop.

Success!!
I went to a tire store and ask if they could scan the sensors. They said a magnet was in the end of their scanner, but it didn't work.
Then I used my hard drive magnet (not moving it around this time) and their scanner read all four. Went home and successfully training all four.
The key was keeping the magnet stationary and it trained each within seconds. I did them all back by the receiver in the left rear.
So this what I've learned:
1) the sensors don't need to be mounted and installed on the car
2) the current mounted ones don't interfere with traing the new ones
3) they don't need to be pressurized
4) don't move the magnet around while the received is scanning for codes
(I guess it opens up the internal switch)
5) the tire store said most cars don't require a magnet, they train by just driving the car??
I can now feel confident these will all work when I install new tires later on this year.
Thanks for all the input.

Out of curiosity, where did you get the idea that you needed to keep moving the magnet around? All instructions just say to hold the magnet over the valve stem while training a sensor.

The above statement may be true on some cars, but it's definitely not true for any C5 Corvette.
