The other day all 3 lights went on. This has happened before, usually after being in snow for awhile. Putting the ignition on position 2 and pressing the run flat reset button has always taken care of it. Well, there was no foul weather and while the button turned them off, they kept coming back on. Now the button won't even reset them. It's probably a bad or blocked sensor but I really don't know much about them. Can anybody offer any troubleshooting advice?

The only change I made to the car was putting on aftermarket wheels when I went to summer wheels from snows. But the lights didn't come on until almost a week later so I don't know if it is related.

Do a search for "trifecta" or "ABS, DSC andTire Pressure light" and all your questions will be answered

well anyways it's probably a wheel speed sensor.

just got this replaced at the dealership 2 weeks ago.

This is what I've ascertained. Not having anything to pull a code is there a way to determine what wheel it would be in the event I do it myself?

When it happened to me there wasn't a code.

From what I heard its usually a front sensor, and usually the passenger side. YMMV
