I just mounted a set of Mountune/OZ Racing Alleggerita HLT rims with the OEM Bridgestone Potenza RE050A tires in 205/40/17 size on my 2014 Fiesta ST. The tires and wheels had TPMS sensors installed from Tire Rack.

I also purchased a Ford Trigger TPMS tool from Tire Rack and followed the following procedure for calibrating the TPMS sensors:

If your vehicle has push-button ignition:

"1. Make sure all tires are inflated to the vehicle specifications.
2. Make sure ignition button is OFF then press and release the brake pedal.
3. Hold the ignition button down for 2 seconds, release it, and then tap the button once. The vehicle should be OFF. Hold the ignition button down for another two seconds, release it, and then tap the button once.
4. Hold the ignition button down for two seconds again. The vehicle should be in RUN mode, engine off.
5. Press and release the brake pedal.

6. Tap the ignition button once so the vehicle is OFF.
7. Hold the ignition button down for 2 seconds, release it, and then tap the button once. The vehicle should be OFF. Hold the ignition button down for another two seconds, release it, and then tap the button once.
8. Hold the ignition button down for two seconds again. The vehicle should be in RUN mode, engine off.
9. The horn should sound letting you know the vehicle has entered into TPMS relearn mode.
10. Place the top of the FORDTRIGGER on the sidewall of the driver's side front tire in the location of the valve stem.
11. Press the button of the FORDTRIGGER tool. The vehicle's horn will sound letting you know the sensor has been learned.
12. Once the horn sounds, move on to the passenger side front tire and repeat the process. Each tire should only take 30 seconds or less.
13. After the passenger side front tire has been learned, continue on to the passenger side rear tire and finishing with the driver's side rear tire.
14. You may now turn the ignition to OFF. If the horn does not sound, the sensors were learned successfully. If the horn sound twice, then the process must be repeated because there was a malfunction."

I am able to get stage 9 in the above procedure so that the central nav display in the car says something like "Calibrate or Learn left front TPMS sensor. I quickly hop out of the car and hold the TPMS triggering tool with the arrow pointing toward the sidewall of the tire near the valve stem. I hold the green button down and a little red light comes on for a few seconds then disappears. However, the car never honks once to indicate that the TPMS sensor has been learned by the system. I try holding the button down multiple times with no luck until the car honks twice to indicate that the procediure was unsuccessful.

Any ideas on how to resolve this short of taking it in to the dealer? As background info, I have removed the OEM rims and winter tires with their TPMS sensor far away from the car and tried driving the car for over 20 minutes. Interestingly, I have yet to see a TPMS warning light go off in the dash display even with the new rims and tires.

Thanks for any advice you can give me.

I put the head of the trigger tool just towards the outside of the wheel right next to the valve stem (still on the rim before the sidewall). So in other words, you have the center of the wheel, then valve stem then head of tool then sidewall. That usually works for me. Also, I bought the more expensive tpms trigger tool from tirerack.... The ateq vt15. For that one, I just need to turn it on then press the left button once when placed above the valve stem. Car will honk in about 3 seconds for driver front tire and then almost immediately for the rest.

When i forgot to reset the sensors, the tpms light did not come on for at least 100 miles

have you tried a different wheel/tire? It's possible you have a bad sensor. The car doesnt know which corner you are on... Try a different one and see if the horn beeps. I put a set of wheels and tires on my car with a new set of sensors and one was bad. I initially mounted it on the right rear so it was easy for me to figure out the sensor was no good because both sensors in the front worked for me.

edit: Stupid Swype!

Thanks, I'll give that a try.

Dang it. Tried all of the above suggestions to no avail. On the plus side, starting the "learn" mode on the right front--as opposed to the left front--tire did not have any different outcome so I am hoping this means the TPMS sensors themselves are not the issue. Will take it into the dealer to see if they can resolve the issue. Thanks again for the feedback.

Let us know what they figure out!

 

[rcl4668]

Will do.

Any update on this old thread? Having the same issue.

You didn't mention if you had remembered to have the doors closed. .. there has been much discussion, about this... but basically when I did mine i did it without those delays... so..... shut door... hit the brake, on, off, on, off on. ... hit the brake pedal. then turn the car off... then on, off, on, off, on... the horn should sound....go to the driver side front.. use the tool.. you get a beep? all good... if not... ?????... then work your way clockwise around the car...

do all this without pushing the clutch pedal.. you don't want to start the car, just turn the dash on and off..essentially the ACCessory postion of car without a fob thingy...

TPMS calibration was eventually done at the Ford dealership. It took a few tries but it worked. Now, the tires and TPMS sensors work fine and I have been able to recalibrate at home using my own Ford Trigger tool.
