TPMS sensor error - sensor battery life ?

[dabangsta]

Generally the battery is good for ~10 years, so you might be at the end of life for one or them all.

 

I finally had an intermittent one in a 2010 Fusion, but so far they are still working in my 2012. Personally I buy very cheap sets off Amazon (for the 2010, for spare winter rims and tires for 2015 Fusion) and they work at as long as the life of the tires so far.

 

Is it a solid TPMS light indicating a low tire, or a blinking one and saying system fault? There are other reasons for faults, my 2017 Escape gave intermittent issues due to a dash cam, then due to a cheapo USB power point (also affected keyless entry distance, needed to be within 5 feet to unlock).

I've got a TPMS system fault showing on my 2013 Ford Edge Sport, its been sat for a while and this could be part of it... but the car is at an age where the sensors will go south due to old age. I am getting fault B124D:02 indicating 1-3 sensors are failing, however the service manual and Pinpoint Test G says it could also be the TPMS module itself under this code. Waiting on a TPMS wake/teaching tool coming, believe it can also be done with letting air out, I also understand that Forscan isnt as precise as the ford scanning tool for this but there are workarounds. 

I have tried pulling the tags on the oscilloscope and dashboard functions to help with pinpointing the issue, I am not seeing any sensors at all however. I have also tried changing the fuse (fuse blades were oxidised) and driving for 20mins, no joy. The screen grabs below are from my testing, leaning towards the TPMS module itself but wanted to check with the community to be sure I was on the right track. 

Please see below screen grabs, appreciate your feedback.

Your sensor batteries are failing. You're at the end of the 10 year lifespan. 

 

When I replaced mine, I used Motorcraft, but the cost is a 2x. Problem with aftermarket is they work when new, but have a reputation for failing after 6 mos or more. Then you're back to square one. Probably depends on brand. You pay more with Motorcraft but you know they will hold up for ten years.

The TPMS sensors installed one year ago in my Edge are working great, and so are the ones installed in my BMW motorcycle two years ago - both sets bought from the same country that made my 4 yo cell phone which is still working flawlessly.

Just had my first TPMS sensor die in my 2011 SEL.  I'm guessing it's a good idea to replace all of them  since they're 13 years old?. Any decent aftermarket brands out there????

I ended up ordering 4 Schraders on Amazon for $29.00 each. Looks like they were take-offs and were all manufactured around July of 2023.  Was gonna replace them myself but it was too cold so I had Discount Tire swap them out for $88.00.  Originals were manufactured in August of 2010 so just over 13 years before the first one died.

Yes.

Update:

 

One of the four TPMS sensors installed two years ago is failing.

I think I'll go with US sourced OEM sensors from now on, or the programmable Autel sensors like the ones I have in my wife's BMW X5.

Looking to get a set of four and pop the bead on one side and replace them all

 

I have a question - do you know if the metal stems can be used in place of the rubber ones that came with the 21" Sport wheels?

My 2015 Edge Titanium show this symbol:  --  on one wheel when I select the tire pressure screen. Other 3 tires show 35psi.  Clearly a new sensor is required but it got me to thinking -  these things must contain a battery and therefore being 10 years old now, should I be expecting the other three to go soon?  Is a dying battery the most common way for these to fail?

Battery, yes. 8 to 12 years is normal battery life.

 

I had a sensor fail, would fail and come back to life. On and off for a year or so. Finally failed. When I had it replaced I had all four replaced. Car was 12 years old.

 

Specified Motorcraft senders, dealer was used to supplying chinese and they sometimes fail after a couple of years. He had to check all over the country to find Motorcraft, so few requests for OEM. Finally found four in Louisville. He told me they had around a 20% failure rate, not right away, year or two in use. 

 

I replaced all four as I didnt want to get one fixed and turn around and have another one start. But if you only replace this one, its possible you'll get a year or two more out of the rest. Motorcraft will run around 2x to 3x more expense, but then I only use OEM. Dealer likes to use NAPA and that's just cheap junk in my opinion. Hate NAPA.
