TPMS - Troubleshooting, Repair, wheel sets, DIY

[ckreuth44]

Im new to owning newer cars, these things are rolling appliances / computers. I have a '22 Mach 1. Right on schedule 1 month after warranty, I lost a TPMS. I dont have an FSM for this car yet so is this likely the TPMS itself or is it possibly a pickup sensor?

What I mean is the car must have multiple car side sensors so it knows what tire is at which corner... I hate to keep dropping off my car at the dealer every year for something. What I WANT to do is take the faulty wheel off and bring it to them and have them replace the TPMS and re-balance.

But, what if it's the car side sensor? I assume I can flip the wheels side to side and see if the dead wheel "moves"?
Do I need some tool or Forscan to get the car to recognize and learn the new TPMS?

The dealers near me so far in CT are not great so I'm really not looking to keep leaving my baby with them. I'm very mechanical and steeped in technology but have owned older cars until recently. I feel the need to be as self sufficient as possible.

I plan to have a second set of tires and wheels for track and or colder weather so bring to the dealer for this crap is a non starter. What do I need to know?

Also, if anyone actually likes their local CT dealer service-wise or a reputable speed shop LMK, TIA!

The S550 has two antennas for the keyfob. One is in the trunk, which is the primary, and one is between the seats in the console. The one in the console is used for reading dead keyfobs that a driver places in the cup holder. The antennas are also used to read the TPMS. I never saw info antenna which is used for the TPMS and likely only the engineers deep in Ford know which is used for the TPMS. For your case, the TPMS is probably the issue because the other three wheels are providing data. One option is get a new TPMS, program it to the car to make sure it was the issue, then take the wheel and TPMS for install.

In the rear of the car, associated with the parcel shelf, is an antenna. This antenna receives signals for two purposes: 1) Tire Pressure Monitoring System wheel sensors and 2) your key fob, for door and trunk access. Both TPMS and the fob operate on the same frequency.

That you lost only one wheel indicates it's a problem with that one wheel.

Check the placard in the door jamb. Ensure all four tires are set to the pressure referenced. The vehicle is programmed to that pressure. Any one tire with a pressure too high or too low can alarm the system.

If there are other sensors within 3 feet / 1 meter of the vehicle, remove them; these could be confusing the car. For example, if another set of tires with sensors or another vehicle in close confines, the car might not know which wheel is associated with the vehicle. Three feet is the minimum standard. I prefer keeping them at least 10 feet / 3 meters away.

The car will auto-sense the tires and their sensors, often within a few hundred feet of driving.

Yes, you could try flipping the wheel to see if the problem moves.

Tire shops do have tools which can illuminate the sensors, setting them off and confirming their operation. IDK if one would do a courtesy check for you on that one wheel or not. You could drive the car up, get a check and an estimate.

You're out of the bumper-to-bumper warranty, but within the powertrain warranty. I think most people would agree a sensor should last more than three or four years. Some dealers are better than others. It might be worthwhile to locate one and chat them up.

I removed my factory wheels and replaced them with and aftermarket set. On the second set, I installed Ford Performance sensors. If you do confirm one sensor has died, it might be worthwhile to replace all of them. It's OK to replace one at a time. Maybe it's just the one. Maybe a bad batch. If you replace all four, I've found the following to work well.

While I had a shop install the sensors and tires on the wheels, I then took them home and installed the wheels in the garage. Within 100 yards / 90 meters of driving, all four sync'd up. They've been working great for the last four years.

Edit,

Specific to TPMS, each wheel has its own sensor. These sensors transmit radio signals in all directions. The receiving antenna in the rear parcel shelf will pick those up, digitize the information and send it to the car's Body Control Module. There are four sensors, one inside each wheel. And then there's the antenna. There are no other sensors associated with TPMS.

That TPMS continues to work for the other three tires and you're not having issues accessing the vehicle with your fob clears the antenna, wiring and programming in the BCM.

Ford TPMS sensors for the last several years have been auto-sensing. There's no need to train them to the vehicle. Driving for a short distance should activate the sensors in the wheels. Once lit and transmitting, the vehicle should recognize them and add them to the display.

Where in Connecticut are you? We have plenty of speed shops here.

The display tells you which wheel it is. Driving the car will typically reset it if its lost signal. Just buy the training tool and try reprogramming all of them. Or...just buy one new TPMS and have a tire shop replace it.

It's pretty easy to swap out the sensor in a wheel. Take the tire off, release all the air, break the bead and then push the tire down at the stem and remove the old one and insert the new one. YT has a bunch of video's on how to do it.

I use this tool below(12 bucks) to make the system quickly re-learn them when I rotate tires or install new ones etc. You can also do it by releasing air in the tire and the system will recognize that corner and beep the horn when learned, but then you have to re-air up the tires when you are done.

Search FORD TPMS on YT, you'll have mucho info about how the system works and the different ways to re-set or have the system learn each corner.

Just be warned, some of the video's tell you incorrectly how to get into "learn" mode.

Hold the brake down firmly and release
Hit the on/off button 5 Times where you end up in accessory power on
Then hit the brake again and cycle the on/off button 6 times and you'll end up back in accessory power on and the horn should beep telling you that you are in TPMS learning mode and then follow the direction in the info screen in the center of the display

Here's a good video that shows it

All my fords just need to cycle the key three times.
Press and release the brake, cycle the ignition three times and leave the key in the on position on the third cycle, press and release the brake then cycle the ignition three more times again, leave the ignition in the on position and the horn will chirp, you are now in the learn mode and you can use your scan tool to reset each sensor starting with the drivers front (1) passengers front (2) passengers rear (3) drivers rear (4) if all four chirped as you were doing this you are done and your TPMS light should be out. You should be able to replace the bad sensor without removing the tire and as new as your car is you should not have to replace all four sensors. If you don't have access to a tire changer this is not an easy process, so, take it to a quality tire shop and let them install the sensor. Bring it home and reinstall the wheel torque the lug nut and redo your relearn process and you are done. I order all my Motor craft sensors from Rock auto .com, the cost is around $45.00 each.

I just had an independent auto repair shop close to home replace a faulty TPMS on my mom's Buick. $77 parts and labor. Hardly worth any effort on my part for that little.

Dealerships and tire shops will have a tool that can check the status of the TPMS sensors. For a 2022 car, assuming it’s the original sensor, it’s probably close to being end of life. The battery only lasts so long (5-6 years is what most shops have told me over the years). Could also have a sensor that has gone bad. It happens. Pretty inexpensive to replace and any decent shop can do it. If you don’t have a good dealership to go to, find a reputable tire shop of your choice (Discount Tire, Belle Tire, etc).

Ford claims that the Motor craft have a battery life of ten years. I put new tires on my 2015 that I bought last year. It still had OEM sensors, and they were still working but I bought all new sensors, Motor crafts, as long as I was putting on new tires, I didn't want to take a chance of the sensors failing. I bought them from Rockauto,com for $180.00 for the set. I have my own tire changer and balancer and did the assembly myself. All is good.

I also got 10 years out of my original TMPS. They will typically all go bad around the same time. All 4 of mine went out within a couple months. I had the OEM Motorcraft replacements installed.

Yup lifespan about 10 years for sensors. Got a ‘15 GT and first sensor died after 9 years 11 months. I then waited for the 2nd to die which was 10 months after the first. Bought Ford sensors and training tool from CJ Pony parts for $104. Tire shop DID NOT demount tire from rim. Simply break bead at the sensor push out old sensor and push in new one. No need to rebalance. Use supplied training tool to sync to vehicle. Bada-bing, bada-boom!!

My 12 Edge just had sensors last year.
My 14 Fusion is still on originals.
Costco did the ones in the Edge for $200 otd. They sync and work fine.

Lots of good info thanks for the replies. I took it to the dealer for an oil change and this. Giving the new dealer a chance to not annoy me. They did not offer to cover it but whatever moving on with life.

Guess we'll see if I need to re-train when I inevitably end up with a new set of tires/wheels
