Default TPMS Learning

is it possible to perform TPMS Learning at 0 PSI or does the sensor have to be under pressure for the learning process?

Training can be done at 0 pressure.

Some people even try training them before they mount new sensors in the wheels to make sure they work. It is also easier to get the magnet on them when they are held in your hand. If you mark each sensor for which position you trained them for, you can mount them on the correct wheel tire for that position and when you put them on the car they are already trained.

I've been trying perform the learning process but haven't been having much luck. I've been using a 15 lb "pick-up" Neodymium magnet like this one:


Do I need to use a horse-shoe magnet like this instead?

the parts dish didn't work either. I think the batteries are dead.

If I buy new ones, are 25648293 and 25773946 interchangeable?

Just ordered New tires (non run flats) and 4 new TPMS (delco) as my exisitng sensors are 10 years old but still work. Before I mount the tires I wanted to program/learn the new sensors. Turns out, one would NOT learn so it is defiective and I had to order a new one. A good reason to program/learn those suckers before you get them installed on the rims and it is a lot easier to do the learning/programming while you are just sitting in the drivers seat.

What is the actual procedure your doing here?

Please explain how you program each, for each wheel position on the car.

You absolutely want to train before install. You would hate to install them just to discover one wont work and have to unmount the tire all over again. I just used a silver sharpie to mark them and train all 4. The handed them over to the tire shop who mounted the tires.

Those donut magnets aren't easy to find at local stores / hardware places and anyone that works on their own car has at least a basic socket set or can borrow a socket. Works like a charm and puts a magnetic field around and over the entire valve stem, not just the sides.

You don't need a donut magnet that goes around the valve stem. I just use a square ceramic magnet and the sensors program fine.

Question regarding the magnet. I assume the ring/donut magnet is recommended in order to get a sufficient magnetic field around the sensor. Would a powerful rare earth magnet (like out of a dead hard drive) work if just placed adjacent to the valve stem?

Just get a regular plain old magnet from around the house as long as it's small and sufficiently strong, then put it on ratchet end side of a steel socket from a socket set and you've got your circular magnet. Works perfectly and no need for a special 'donut' magnet. Start at driver left front and go clockwise and wait for horn sound as you do each sensor. 45 seconds per wheel = plenty of time.

Hard drive magnet works fine.

I read somewhere that the absolute correct magnet was this one:

So...if the TPMS learning procedure fails, as in no horn beep from magnet at LF sensor, no DIC change from "LEARN L FRONT TIRE" after 45 sec, I assume that means the LF sensor (or its battery) is dead?

So, instead of LF as the DIC asks, just use another wheel? I guess the computer has no idea which wheel is actually being reset. I tried magnet between stem and wheel, outside of stem, and with socket as suggested earlier. Will try another wheel.

What do most folks do when getting new tires, BTW--just assume that their current TPMS sensors are good and don't need replacing? Bring another set and replace batteries in old set for the next time new tires are put on?
