It's solid on the top, no place to put the sensor "inside".
Tire shop is closed today, I'm gonna do some watching of these vids after work and see if I can go by tomorrow and use his scan tool. Small town shop, I was using it when I was there. I just don't think he's ever had to do this before. (I know the tool was loaned to him from his brother in law). Besides, I need to get my hands on the old sensors if at all possible to confirm the part number on it regardless.

 

I also don't think these are any of the programmable sensors listed.

 

That tool can also do the insertion operation, from other vids I looked at.

I think the metal inside the rubber stem acts like an antenna.

From what I have seen all of the numbers that have appeared in this thread are applicable, I was unaware of the programming needed for blank sensors.

 

Interesting.............

Do you know the Mz of the sensors ?
When I replaced mine they were AC Delco #20925924 w/315Mz. These have metal valve stems for alloy wheels. I programmed them by doing the tire air pressure procedure.

 

315Mz

 

Here is the part # off of my old ones.
25920615

 

 

So, the correct replacement should go in with no programming though, correct? Plug em in, go through the relearn and move on right?
