TPMS sync tool and procedure

[Mooz80]

Hi,

I'm in the process of shopping for a winter kit (wheels, tpms, tires) for my Nautilus 2025. I can save around 500$ if I buy a kit pre-mounted, but I need to have the TPMS synched by myself.

All the TPMS tools found so far seems to advertise that they work up to 2023 models. Anybody went throught the same and has a working TPMS tools and procedure that works?

Some websites states that the car may recognize the new TPMS after driving for a while, some other mention that I need a tool and procedure. Don't know who to believe

Thanks,

Per the '24 Nautilus WorkShop Manual (WSM - '25 should be exactly the same for this), there's a series of in-vehicle button presses that can put the vehicle into TPMS Training Mode. Nothing too crazy.

Once in Training Mode you use a TPMS Activation tool to "wake up" each of the tire TPMS sensors, in sequence LF (Left Front) - RF - RR - LR, so the car learns which is the sensor for each individual tire.

The replacement OEM TPMS sensor for the '25 Nautilus is the F2GZ1A189G, a 433 MHz device. The part is listed as the OEM replacement on multiple Ford/Lincoln models as far back as model year 2015.

The OEM 204-D081A TPMS Activation tool is very pricy. There are TPMS Activation tools down in the $15 range that list as compatible with Ford/Lincoln vehicles I see listed for the F2GZ1A189G, so I would expect those tools would be usable for our '25 Nautilus.

Hi, thanks for the detailed replied. With a couple of research, I found the way to get the car into "training mode" without purchasing the Workshop manual.

I will buy the TPMS tool (TPMS 19 seems to be the model to go with) and try with the actual tires before purchasing new ones. That way, I will know for 20$ if the tool work before purchasing the kit.

Hmm. So does this need to be redone when rotating tires?

Not clear to me yet. Based on some other Ford/Lincoln models forum, once the car has learned the sensors, it would automatically update information after tire rotation. Driving a few miles above 20mph would be enough to update the new position

Have not tried it myself yet to confirm. But, I had 2 sets of tires for my 2023 Explorer and I had nothing to do when changing them in spring and fall. So I assume Lincoln will behave the same.

I have never noticed it in years but was curious. I would find it hard to believe tire shops would like it.

You do the retraining if you want to get the right mapping of which sensor corresponds to which of the four wheels.

"It is not necessary to train the sensors after a tire rotation on vehicles with the same front and rear tire pressures however, the BCM cannot recognize the sensor identifiers have been moved to different positions and retains the original position information for each sensor."

Some vehicles have the vehicle-side TPMS antenna in all 4 wheel wells, but many/most (Including, based on the WSM, the Nautilus) do not, so they need to be trained. Honestly, it's a pretty trivial activity, a couple of minutes total to put a vehicle into training mode and then run the LF-RF-RR-LR cycle with an activation tool.

• Vehicle (or TPMS Activation tool) sends out a 125 MHz "ping" to get the sensor to transmit. The Activation tool is purposely a low-power emitter, so it wakes up just the one sensor at a time.
• Sensor sends back sensor ID, tire pressure, and, for some sensors, temperature, on either 315 or 433 MHz (which TX freq. is vehicle model dependent)

There's also a Bluetooth Low Energy (BLE) TPMS sensor, but best I can tell it's only OEM equipment on 2020+ Teslas.

I had my tires rotated and after that I had a flat. The TPMS accurately identified the low pressure. The rotation was done at the dealer. I wonder if they retrained the TPMS?

I expect so, as it's an in-the-noise amount of time to do.

On our RX350 I got new tires/sensors a few years ago, one of the sensors hadn't stored properly (I noticed that when I started driving home). I drove back to Goodyear, the tech came out with his activation tool, redid the training sequence out in the lot. Less than 5 minutes from him coming out to me driving back home.
