I rotated the tires a few weeks ago and didn't do anything with the TPMS. As far as I know, it only warns of low pressure, but not which tire position, so moving the tires is not an issue. But I could be wrong. The manual should have some info as well.
I confirm that.
Rotation will not do anything to TPMS. This system will warn you if pressure drops below 20 PSI (+/- 3 PSI).
Rotation will not do anything with that. Moreover, even if you loose pressure, and bring it back again - it still will be fine.
I agree. Rotating your tires will not affect the TPMS.
However, the TPMS more than likely knows where each tire is mounted. When there's a TPMS error, say sensor malfunction. The TPMS will tell the factory scan tool which tire it is according to 1,2,3, or 4. Depending on the manufacturer, the number one tire can either front left or right, or even back left or right. The service manual will tell which tire is where. That info is needed when the sensors have to be manually reset and programmed. Hence the funky TPMS reset tool that every tire shop and dealer now has.
On some new cars, resetting the sensors are done by taking a short trip above 15mph or so. Every vehicle model and manufacturer has it's own thing at times because of the introduction of revisions to the sensors.
I am currently intimately familiar with the TPMS on the rondo and can shed some actual knowledge. I just had my TPMS controller replaced under warranty due to constant illumination of the TPMS light when driving. Quick system description; each wheel has a sensor/transmitter that sends info about both pressure and temperature wirelessly to the receiver which is in the center console of the dash. It listens to all 4 transmitters and reports status. It receives actual data as to temp/pressure, but only displays the TPMS light if there's any (and I do mean any) problem with the system, and the tire light if there's a low pressure/high temp condition. Each sensor is told what position it's in, and then the controller is told which transmitter is in which position. Once again, however, the data is irrelevent to the system. As long as it receives all 4 signals you can rotate the tires wherever you want. If you have a problem with the system, however, they'll need to retrain it for troubleshooting purposes.
