New OEM TPMS not working

[diymirage]

So for the guys who installed them and just drive for a bit and they became synched…..how does the truck know which sensor is in which tire?

And that’s literally all you had to do? Just install and drive? No special reset button, no key turn sequence, etc?

Yes sir, just like that

Ive bought used wheels online with TPMS, bolt them on and the car knows exactly what wheel goes where

Ive also bought brand new aftermarket ones with generic sensors...same deal

What brand were the $46.79 ones? (Was it each, or that price for all 4?) was it something like this….aftermarket ones….Do you think something like this would work?

They were OEM Mopar sensors from local Ram Dealer, purchased them from their online store. Was free shipping.
Price was each.

Check with site vendor Benny on this site, for his prices. If they are on sale, the OEM sensors are price reasonable and work better than Off-brands.

Hey guys,

So I’ve searched and I’m finding conflicting answers, so thought I’d describe my scenario and hopefully help me!

So I have a 2013, and the tpms were showing a correct number for one tire, and nothing for the other 3 (I’m assuming those 3, the batteries were dead since those sensors have been in there for at least 5 years) — so this must mean that my receiver or RF hub or whatever is working, right?

So then when I got new tires and wheels, I purchased 4 brand new sensors (Mopar #56029398AB) — which they said was compatible with my vehicle.

From everything I researched, since these were genuine OEM sensors, I should have been able to simply drive the truck for a while, and the system should have picked them up, no?

Well that didn’t happen for me….it simply shows “- -“ for each tire now.

What did I do wrong/miss?
-Did I actually need to do some programming?
-Could the sensors I got have been dead?
-Was I given the wrong part number?


It’s been months since, and still nothing is displayed — so I guess the “just drive on them and they will eventually show up” hope is out the window now lol

Anyways, I’m getting my winter tires put on soon, so thought it would be a good time to get new sensors installed while the tires are off.

If the only solution to getting the OEM sensors working is to go to the dealership…..I might just buy some aftermarket ones on Amazon….then I will definitely need a programming tool that works with whatever specific aftermarket brand the sensors are, right?

Can any of this be done in Alfa OBD?

Also: before swapping the sensors (when only one was working), the TPMS warning light would be on the dash. Now since replacing them, the warning light is no longer on.

Thanks guys!!

On my 2014 Laramie they were programmed by installer and drive a few mles to register location on truck. When rotated they register new location after a few miles also.

I had to get one of these:

https://www.amazon.com/gp/product/B0BQ31D4J9/

to program mine on my 2011 1500. Not cheap but cheaper than buying 4 genuine OEM sensors, and the machine works on all my other cars too.

For those who are consistently having issues with the TPMS either blanking out or not registering one or more of your wheels, I found a solution that solved my problems and it involved relocating the TPMS module to a different location in order to be able to effortlessly receive the signals from each wheel. I made a video explaining what I had to do and this was over a year ago and have not had any issues since. I had put 4 new Mickey Thompson Baha Boss LT 305/55R20 tires on Fuel wheels with 4 brand new Mopar TPMS sensors on my 2013 Tradesman 4WD. Within 2 miles of leaving the shop, all 4 sensors came online, then they went out completely after another 2 miles. I tried reprogramming and they kept going out over and over and over again. The problem turned out to be that the wheel sensors were not being picked up by the module because the signal(s) were not strong enough penetrate all the metal mass between the wheels and the module... Moving the module to a location that ensured a strong signal to each wheel was the key...

Here is the video that I made and I hope it helps a lot of you out...

They’re SUPPOSED to learn automatically.
You can manually program them individually with the alfa, but you need the sensor ID off of each one.
The only way to get that is to have them in hand, or read them through the tire with a TPM-RKE analyzer.

Just a bit of clarification. OEM sensors are pre-programmed. Aftermarket, including Schrader, Bartec, ATEQ, Continental to name a few sell what’s called a programmable sensor. Meaning, the sensor is common to many makes and models, however it requires a programming tool to configure it to communicate with your vehicle. Your vehicles tpms module will re-learn the sensors. If you want to understand more, here is a source with several articles https://tirereview.com/category/service/tpms

Someone mentioned the possibility that the BCM actually communicates with the 4 Wheel Sensors to register Wheel Position
Do they communicate by wire or Bluetooth ?

The sensors transmit data via radio. For our Rams, they are UHF 433mhz.

According to GPT AI, TPMS sensors transmit the following data to the car's TPMS module:

Tire pressure: The pressure level of each tire
Tire temperature: The temperature of each tire
Sensor ID: A unique number that identifies the sensor and its location on the vehicle
Acceleration: The acceleration of the vehicle
Direction of rotation: The direction the wheel is spinning
Battery life: The status of the sensor's battery


As to how the TPMS module determines which sensor is in which wheel, the sensor location is recognized by comparing the wheel pulse data from each of the individual ABS wheel speed sensors to the acceleration values of the individual sensors. The TPMS module does a learn cycle each time the tpms sensors wake up, so any time you rotate your tires, the locations should update after driving awhile.

I purchased a Tester/Programmer just to keep ahead of these sensors. Not to expensive.

Just an update Guys: I ended up purchasing these random sensors off of Amazon because they would arrive same day, otherwise I was planning on purchasing the Scrader ones from Rock Auto (but they would have taken a few days to arrive, and this weekend was the only free time I had to get my tires installed)

Went to my local tire shop to have my new tires installed, and got them to throw in these Amazon sensors.

I drive about 10 mins, the TPMS light in the Dash flashed a couple times and now BOOM! working sensors!!!

I can’t believe the “Mopar” ones I purchased on eBay before (for double the price) never worked, and these random Amazon ones worked. I guess I never even thought that people would counterfeit car parts too.

Thanks for all your help Guys!!

Interesting. Not real sure how many TPMS systems actually transmit all of that information. On some vehicles maybe they do. However each different parameter requires an additional type of electronic device built into the sensor. So you would need a pressure sensor, a thermocouple for temperature, and an accelerometer. Not sure why you would need a separate sensor acceleration or direction of rotation. You already have wheel speed sensors for rotation, and almost all new vehicles have accelerometers that are required for the stability control systems to work. Also not sure why you need tire temperature? Just having the pressure sensors will basically tell you this since pressure and temperature are directly correlated. The ECM could do a calculation on how much the tire pressure increases over a period of time and compare that the ambient temp sensor (again, that almost every new car has).

Glad the new ones worked out ! My guess the E Bay ones were fake or used w/dead batteries or old ones sitting on a shelf several years
