HOW TO: Retrain your TPMS Sensors (2008-2011)

If you have new TPMS sensors in your wheels and want to teach your car's computer to relearn which sensors to be looking for, this is how you can do it. Note that I'm going to go over the method that I know works (because I did it), and then the methods that I was told would work, but didn't. I only mention that because they MAY work for your 2008-2011.


Tools you'll need:
1. Generic Ford TPMS Reset Tool (Part number 8C2Z1A203A)
2. A set of TPMS sensors that your car is not currently linked to


Process:
1. Get in your car
2. Close the door
3. Release the parking brake
4. Place the key in the ignition
5. Rotate the key forward to the ON position, then back to the OFF position THREE TIMES. When in the ON position, wait about half a second before going back to off.
6. On the THIRD time you rotate the key to ON, leave it there.
7. Press the brake pedal, then release it
8. Rotate the key to OFF.
8. Repeat steps 5 and 6 (OFF to ON another three times, staying at the ON position on the third time)
9. If you've done this correctly, you'll know you're in RELEARN mode because your car horn will chirp once.
10. The odometer message block will inform you that you are now in sensor relearn mode.
12. You will now be going to each tire on the car to tell the TPMS sensor to broadcast its code to the computer. You MUST do them in a specific order, which is:
  • Driver side front
  • Passenger side front
  • Passenger side rear
  • Driver side rear
13. Starting with the driver side front wheel, place the TPMS reset tool against the tire where the sensor is, and press the button. You should be aiming the reset tool directly at the sensor through the tire's sidewall.
14. If you placed the reset tool in the correct location before pressing the button, after about two seconds your car horn will chirp, letting you know that it has accepted that sensor.
15. Once all four sensors are accepted, you can turn the car off and let out a sigh of relief. You won't have that annoying error on your dash anymore

I know that not a ton of people will run into this problem, but as the batteries in your sensors die in a few years and you need to get them replaced, I hope this helps (and saves you money)...especially since Ford told me I'd be charged $80 for them to do exactly what I outlined above. Seeing as I have two sets of wheels (winter/summer) with two DIFFERENT sets of sensors, knowing how to retrain the car's computer is VERY helpful when the seasons change.

Now here are the methods that I haven't confirmed, but are rumored to work:

1. Instead of using the TPMS reset tool you may be able to use an industrial strength magnet. When walking to each wheel, place the magnet on the sidewall of the tire next to the valve stem (or location of the sensor). I am not sure if this will work for the band-style sensors.
2. I was originally told a different method of getting into the relearn mode, which was moving the key from OFF to ON 8 times then tapping the brake. This didn't work for me.

Please note that the style of TPMS sensor CHANGED starting in 2010 models. All 2008-2009 Foci have the band-style sensors, and all 2010-2011 Foci have valve stem-style sensors. I was told that the sensors are incompatible, but I know for a fact that both transmit at the same frequency (315 MHz), so you MAY be able to train 08/09 sensors to a 10/11. Until I test it myself and know for a fact that they are incompatible, I'm going to leave the possibility open.

Uh one of my sensors broke (band style) so when I got tires I just had them all removed. I dont like random stuff inside my tires anyway. And a tire pressure gauge and a bike pump work just fine.

How much is the TPMS tool vs the cost of 4 new sensors? Or can you just replace the batteries in them? We have a tire machine at work so breaking the bead to get to the sensor is no issue for me, I don't need a dealer to do it.

-The TPMS Reset Tool cost me $43 including shipping from Tousley Ford.
-Four (4) new stem-style sensors cost me $213 including shipping from Tousley Ford.

You can't replace the battery on the sensors, so if there's anything wrong with them, the only solution (other than trying to re-sync the sensor) is to buy a new one.

FYI if you get into an accident and it was cause by your tires and the insurance see your TPMS is faulty for any reason, you will be at fault no matter what. It also may cause you to not be able to get your vehicle fixed

Ah, I see. I would honestly prefer my car has no sensors. I didn't even realize it had them until I did my tires.
