Just had another thought -- are these lights indicating a mechanical failure has already happened that needs attention or

is a mechanical problem brewing that may result in greater expense if not taken care of soon or

is it likely a sensor problem and can be ignored for a while.

I've read a couple of threads on this issue and have no experience/knowledge to guide me here.

What is a tone ring. What does it do?

Bad sensors light up the same ABS/4WD lights as a bad tone ring?

Any particular problem more likely with a 2007, 30,000 mi Escape?
