? On Reprogramming Sensors
I got new wheels and the shop that mounted them did not mark where they strapped them in.These are not the original sensors so I do have to reprogram them.Does it matter where I hold the magnet or just putting it next the tire in general is okay.

Yep, you've got a slight problem that may end up requiring you to open the tires back up to mark the location.

Also - if they're not the original sensors, they HAVE to be 01-04 sensors, as they changed, and are not compatible with the older style sensors.

You can remove the wheels from the car (keeping them close to the car and get into the TPS programming mode and slowly run the magnet around the inside of the rim until the program picks up the sensor. Give that a try. let us know how it turns out.
The strapped in sensor shound be towards the center portion of the rim

I'd make the shop mark the location of where the sensors are. They really should have done this in the first place. Good luck with the reprogram.

Well I put the wheels on anyways.I did nit even try to reprogram the new/used sensors.The dash read 29 psi.Shouldn't it prompt me to program the sensors?I drove it about 25 miles and it is still reading 29 psi.Are the sensors transmitting or is it still showing the pressure from the original sensors?I guess I will have to let the air out of one of the tires and see what it reads.Has anyone put new/used sensors on and not had to go thru the relearn procedure?

If your sensors are the original ones that were programmed at the time they were dismounted they will still transmit. Be careful, they may no longer be on the same place on the car that they were programmed to ie left front sensor in the LF position ect ect...

Well,I started the car today and the dash read service tire mont. system.The place that mounted the rims is out of state so having them remount is out of the question.I guess I will have to remove tires or put on lift and run a magnet around inside of rim and hope it works.What size magnet do I need.Is the bigger the better?I tried wtih a small fridge magnet tonite by sticking my hand in between the spokes but no luck.Do I need a bigger magnet?

Programing Tire Pressure Sensors
Southview, you're going to need a large, strong magnet, a fridge magnet won't work. Usually a strapped on sensor is placed 180 degrees from the valve. There's no telling where your guy placed it unless you speak to him. Can you call him? The programing steps are in your owner's manual or perhaps you can run a search on this forum. There was a step by step do it yourself post, but I can't find it. You may be able to move the magnet around and listen for the horn to honk, but you're best off following the instructions in the owner's manual before you do anything that will just waste time. The manual's instructions are really simple and the only thing that you need to do (not mentioned in the manual) is hurry and program the sensors in the correct order. If you take too much time the programing won't work.

An excellent place to get a magnet is out of a disgarded microwave oven. The magnatron has two KICK *** magnets. I use to repair microwaves and have a whole pile of them.
Radio Shack has a great selection of magnets. Give them a try.
If you have a friend start the Tire sensor monitor program and tell you what tire to go to, you should have loads of time to slowely run the magnet around the inside the rim until the horn beeps. That indicates that that sensor is programed.

Interesting thread and situation. A magnet that I have is called an earth magnet and is the strongest magnet I've seen. I wonder if these are the magnets that are used in a microwave. Whatever the case let us know how you make out.
