You need a special tool for that. Something like this.


And of course the programable sensors.


This set has 8 sensors

Sensors are fragile so having a shop do it is a safer bet.

Don't know how you are going to balance your wheel.
You do not need a $200+ tool to program them. The tool for Fords of that era was around $15, IIRC.


Granted it only does Fords (maybe Mazda too? IDK). You might find more info about the specific tool type in a Ford centric forum.

Briefly searching, that tool may not even be needed for a 5th gen explorer, only earlier generations. It looks like a '12 will relearn itself without the tool.


You might also want to check the above linked forum for lots of other issues related to your '12 Explorer, probably one of the most informative on the 'net... if a youtube video doesn't cover what you're looking for.

I am just going by standard practice, no idea about specific vehicle models. On some cars there is a button or menu option to relearn.

The 2012 Odyssey I had needed the programming tool to relearn on every seasonal change.

Ordered it.

Hopefully it works.

I have a 2012 car and have also had to replace a couple TPMS sensors. It's not uncommon and they're not expensive. Like $50-60 each at Discount Tire.

Might just be unique to my car, or Hondas in general, but if one goes dead, the computer stops reading the other three. No idea why, but I don't really know how the system works in general anyway. (Like, how it knows which sensor is on which tire.)

Every now and then I read of someone getting one with a bad battery... just something to keep in mind.

Got it today and it worked after figuring out the quirks.

Thank you, Thank you, Thank you!

You saved me quite a bit here with the correct info and what to do!

Thank you again.

P.S. Apparently have to hold the remote tool next to the sensor to program it.. can't be close enough to the center of the wheel.. and the programming code was tricky.

For Ford it was Brake Pedal press, release
On - Off - On - Off - On
Brake Pedal press, release
On - Off - On - Off - On - (Off - On) I had to do an extra one to get it to work.

I had a 2001 Toyota Highlander that I drove for about 10,000 miles over 15 years but it was becoming too expensive to maintain. Much cheaper with Ford or even older cars if you can still find the parts.

BTW as someone who has driven a 1983 Toyota Cresside, 1991 Corolla, 2001 Highlander.. the only feature that I would miss in those cars vs modern is the Back Up Camera. I don't know if it's possible to install it in older vehicles but if it is, that's worth it!
I could ask you to further explain your judgment of a Toyota SUV being too expensive to maintain. My brother and his wife dumped a perfectly good Toyota Camry because they didn't want to spend the money to fix a rear door window.

You can tell me whether I'm wrong about this. The annualized expense of buying a new or recent-model pre-owned vehicle is more or less equivalent to a year's worth of the 6-year car mortgage. If you're even spending $1,000 in a year to repair an old vehicle, it's going to save you a lot of money.

Of course, you can get a backup-camera or rear-view camera kit, which comes with the dashboard LCD monitor. I wanted something I could integrate with an Android tablet I installed on my dashboard offering Google Maps, voice-rec and voice-nav, a large music collection and player -- operating through Bluetooth to a receiver device in the 20th century digital receiver's cassette slot. So I found the right backup camera for my old Trooper, which communicates via wireless to the Android.

It all works nicely, but for a minor nuisance of touching the screen a few times to raise the app and connect it to the wireless signal.

I'm always skeptical of new gadgets, but these tire sensors and other features have been around for almost a couple decades. I'm just old enough not to relish new features or wanting to become familiar with them. If I eventually find my new/pre-owned RAV4 Prime in a year or two, I'll be forced to learn . . .
