Most cars after the C5 used the different programming method and most cars did not have TPMS before 2007. Technology improved pretty quickly. Not to mention most sensors were still working so they weren't replaced.

 

At least GM vehicles have what I would call a "proper" TPMS system, with actual pressure readouts being available. many (most?) do not, merely sounding an alarm if any tire is out of limits. The approach from those manufacturers seems to have been, how do we meet this requirement at the minimum cost? Even a friend's current model 5 series is this way.

 

When I reprogram sensors I don't hold the tool on the stem I place it against the tire by the wheel were the sensor sits.

 

 

This post was not needed. Posted twice already!!

 

It was for you, since you were doing it wrong.
Just trying to help.

 

Thanks for the help. The way I do it does work!! I'm sure you have heard the saying, there is more then one way to skin a cat!!

 

It's best to give the right advice on forums like this.

 

Sir, for you to make a statement like that about what I have to bring to this forum is no more then antagonistic and improper.

 

I'm not taking sides here, but Frank, please learn the difference between then and than.

 

Giving bad advice helps no one. If I do it, I would expect you folks to correct me and I will take no offense. It's not a contest.

I am done here.

 

Read my earlier post - no room to get a magnet next to the valve on my wheels. Wiggled it against the inside of the wheel from behind the wheel. Worked perfectly. You just have to be close enough - no exact placement needed.

 

You'll find that JR is always right, and never done. He'll be back.

 

Guys, this thread is very fitting as it will keep me from having to start a brand new one.

The back story: I discovered that I had several punctures in my left rear tire that couldn't be repaired. As it happened, I already had two good tires I could use as replacements. I had a local tire shop switch out the tires and all seemed well. It was a couple days after I had the tires replaced when I got on the freeway and all of a sudden a "traction/active handling" warning came across the DIC. After some experimentation I discovered that this happened as soon as I hit 60mph. I can defeat the problem just by pressing the traction control button but I would rather have things working correctly instead of masking problems. I also discovered that when the tire store mounted the tires, they had put the left tire on the right wheel and right tire/left wheel.
I thought that was the source of this mysterious traction warning. I also thought that if I retrained the sensors, my problem should go away. I followed the above video and got a horn honk on all four tires but the car does still go into traction/active handling as soon as I hit 60mph. Any thoughts on what I can do to solve this once and for all?

 

Your problem is unrelated to the OP's concern, so you're justified in starting a new thread. That said, what size tires are you running, front and rear?

 

Are you getting good tire pressure readings on the DIC? If so, I would have to assume that the TPMS system is working OK.

 

 

Got mine from Lowes in a pack of 3 - pretty cheap as I recall. Any hardware type store should sell magnets.

 

Interesting. I didn't think of that. The tires were take-offs from a c6 Z06. I think they're 285/35-18. I know they're one aspect ratio smaller than the factory tires.
Yes. Both rears read 33 pounds.

 

Need to know both front and rear tire sizes, exactly, no guessing. As 8VETTE7 mentioned you need a difference in overall diameter between the two. If all tires are the same size (or very close to it), then that's your problem.
