Default tire rotation and tpms

So I was wondering, should the tpms sensor be re-sync'd when a tire rotation is completed?

I do realize that there is no easy way to re-sync the sensors and that the vehicle doesn't actually tell one what wheel is low on air. I ask because from reading retraining instructions for other vehicles they are sync'd in a specific order and to a specific location on the car. Once a tire rotation has been completed then the tire wouldn't be in the location that it was trained to.

Now the only way I could see this being a concern is if a sensor fails, would the computer when checked report the location?

I have also read that many sensors are self learning. Case in point, a friend of mine put a set of factory wheel on his Focus ST and never did anything else, and the tpms light never came on. Also on the Focus it is incredable easy to re-sync the sensors. Just turn the ignition on and hit the hazard light button 6 times, then follow prompts to train each wheel by either letting air out of the tire or using a trigger tool.

I also as as at some point I may a set of winter wheels, I want to be able to handle to TPMS system to keep it functional.

just to let you know, there is nothing in this thread that could not have been answered with a simple search and this so did not need its own thread.

1. it does not matter where you rotate the tire the computer does not care nor does it need to be resynced, the sensors in the wheel transmit back the data to the tpms receiver in the car, when the threshold is reached for low tire pressure the light illuminates. The computer would be aware of the updated location when it receives a signal however it does not have the capability to display that location as the vehicle is not equipped with a display to show that info and may require other updates to the receiver. When you scan a tpms sensor you are able to see the tire pessure and other information. The cars ability to know of the tire pressure and etc is simple an economic decision because spending extra money for the display for the consumer can add up the same exact way that the car does not display temperature of engine and other information.

Luxury vehicles generally come with the ability to display the exact location and pressure of each tire. Most manufacturers are now moving to put this on their regular vehicles but it will be a while.

here is a pic of what it looks like

In terms of self learning, American cars, german cars and a few other easily self learn their tpms sensor ids by hitting a button, japaneese cars however require the codes to be in the computer. At times the self learn system can forget the tpms information and joe consumer then panics and brings the car in. I am assuming due to this japaneese opted for a system that would not forget the tpms ids so easily or be prone to electrical interference.

In terms of updating tpms info and switching from summer to winter wheels
