TPMS sensor?

[Tycoon]

Checking the part number, those appear to be the correct type:

If that is the actual package of the units you installed, I have a concern: they were bagged in 2017.

TMPS sensors have two primary bits: an accelerometer and a battery.

As the wheel spins and the accelerometer becomes active, the battery is used to power the sensor, the wheel alerting the car.

Just like a bag of batteries of the shelf, I'm worried those units, if eight years old, are nearing end-of-life, or, have already lost a good bit of their power.

If bought on-line from a third party, it would not be unusual they picked them up from somewhere else, from an old inventory purge or stale inventory, and sold. If they don't work, hopefully they have a return policy.

If bought from a dealer or the shop that installed the wheels, save the receipt.

Very useful comments. This is one of the actual bags. I did not know about the date. I will reply with observations.

Do anyone know if you need to reprogram the car to accept the new sensors ? Or just install them and done ?

I just did wheels and tires 3 weeks ago and the wheels had non OEM TPMS sensors pre-installed. The car recognized them immediately and I did not have a problem whatsoever.

I bought aftermarket ones and they would not connect them went Ford and was fine plus very accurate.

Good points about date.....I did buy a couple Koni Active Struts that turned out to be made in 2019....

Okie dokie. Info: recall mentioned the wheel swap a few years ago and the automatic syncing. I remember that when I did that, it took a few days to sync. During that time the digital readout on the dash was displaying pressure numbers but they were all random and changing. In the recent case, with only the front two tpms sensors replaced, there was no indication that they were not working, but the digital display was showing 39 for one wheel and 1 for the other. After a few days, the malfunction light came on and these numbers changed to --. I bought this programmer from Amazon for a few bucks and used it. Took about 2 minutes. No light and all sensors are synced now.
Interesting that takeoffs synced sua sponte and new sensors had to be programmed.

The ones I bought from American Muscle sinc'd to the car on their own. No programming, nothing

I think some have to be hit with an electromagnetic pulse before they start transmitting. Some don't. I do not understand the mechanism of activation.
