New OEM TPMS not working

[kayla02110]

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!!

Try your local repair shop or tire shop, They have a tool to program the TPMS !
I am not sure but I do not think your 2014 or my 2015 self learns !
So I am curious on to see the replies you get

The sensors auto program if they are TRUE Mopar sensors. Everything from 2009 to 2024 for 1500 & 1500 classic models. Even though the sensors for 09 thru 12 are different than 13 up

This part number shows it fits, however, I'm curious to know where you purchased them and are they pure mopar or counterfeit. As you can see these are expensive sensors. At 101. 62 dollars each.

Might be an issue truck side, I have never had a vehicle have issues recognizing TMPSs

Stock, used or aftermarket

Where did you buy them? Many of the "Mopar" TPMS sensors sold on Ebay and Amazon are counterfeit.

I replaced mine (2013 Ram Sport) with Schrader 29093 sensors from RockAuto for 22$ each. It recognized them within a mile after leaving the driveway.

Thanks for all the replies, guys!

Hmmm I bought the sensors on eBay lol. So now I’m leaning towards them perhaps not being genuine…

Since my old sensor was working properly, I’ll rule out an issue with the truck, or receiver for now.

I went to a local tire shop, and they said they could sell me new sensors that they could program….for $90 each.

I think I’m going to try the Schrader sensors from rock auto….

 

[GTyankee]

Do you have a Discount Tire or American Tire in your area

They have a hand held device that they hold close to the tire to program it.
They move from one tire to another to set them.

The last time, they told me to drive a bit to sync them, but i had to return to the store & they used their tool again

I believe that the TIPM have a wireless connection with the BCM,
( Body Control Module )
The BCM is located just in back of the Drivers Side Head Light
The plastic inner fender conceals it

On occasion the BCM get enough mud on it & that messes with the wireless signal.
In that case, it needs some cleaning

I do not think that is your issue

These are the ones I used. They were pre-programmed, so I didn't have to do anything other than install them.

I'd connect with Benny @AllMoparParts.com a forum vendor here. Give him your vin and he will give you the correct part number even if it's been updated.

Last OEM sensors I purchased were around $62 per sensor. That was about a year ago

As it was mentioned if everything in the truck is working correctly. Real working OEM sensors don't need to be programmed.

I purchased bunch for different trucks(Ram) I own. On Sale in Canada was
4 $ 46.79 Tire Pressure Monitoring System Sensor

That is Canadian money, few months ago. Think about 1 1/2 years ago I paid $60 CA for each.

Turned the truck on, starting driving, 10 minutes they were synced and working.

 

[kayla02110]

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?

Hmm yeah I went to a local tire shop, he told me the tool he had wouldn’t work with the Mopar sensors I had, and that I’d need to go to the dealership for that.

He said the tool he had would only work with one specific brand of sensor — he could sell me those sensors and have them synched…..but say, if I bought other aftermarket ones online, and asked him to synch them, he couldn’t do that because they were a different brand.

Was what he said right? Or was he just saying that to try and sell me new sensors?

Is there anything I can do with alfaOBD to do the same thing a room would? Or a specific tool I can buy myself to have, and use whenever I wanted?

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?

 

[Bigskyroadglide]

The tpms computer portion of the truck is located on the Frame in front of the left (drivers) front tire. It receives the RF signal from each tire and knows where the signal is coming from. I'm not certain where it detects tire location, however I know if you move a tire it knows the tire has been moved. I assume it's based on the distance from the tire to the rf hub.

I'd recommend to you to go have a discount tire replace the sensors you have and have them make certain they work before you leave.

Mopar branded sensors last about 10 years. Aftermarket sensors last between 6 and 8.

I believe you, unknown to you, purchased counterfeit sensors from a less than honorable seller.

Attached is the updated mopar part number and price from a mopar dealer

That is correct.

I used a scissor jack under my trailer hitch to break the bead, then I big C clamp to pinch the tire out of the way.

After I installed all 4, the Schrader 29093, they were working in less than a mile.

As to the "how does it know".

My understanding of the system is, because there is an abs wheel speed sensor at each wheel, the PCM "learns"the sensor locations when you are driving based the rotational speed difference between the wheels. Supposedly, it relearns a lot quicker when you make turns than if you drive strait.

 

[Ken226]

I knew there would be a video on YouTube for this. I thought, surely someone else has thought of it.

Easy ways to break a tire bead at home using simple tools! DIY

This video documents a few easy DIY methods for breaking a tire bead off of a rim using some simple tools. I use a scissor jack, a bottle jack, my truck and ...

youtu.be

But with my 305/55r20 MT's it was a bear clamping the rubber back far enough to access the sensors on the inside, to remove the screws so I could remove them.

Next time, it's going to a tire shop.

So this stuff it says on the item detail page, about the “OR Relearn Procedure” requiring a TPMS tool to write the ID’s to the computer, etc shouldn’t apply to me? Just plug and play?

Yea, I was worried about that too.

I was pleasantly surprised later that day, when I went to the store and they started all working.

I guess the key word in the 3rd sentence under relearn. "may". Mine didn't.

In the 1st bullet point up closer to the top, it says "pre-programmed". So, in my case, they started working on their own.

 

[Ken226]

If you don't want to wait for it to learn on its own, I believe you can program the sensor ID#s with Alpha.

This page, I'm pretty sure.

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.
