Driving home the engine just stopped. The engine yellow light came on on 2006 Mercury Mountaineer

I looked in the book and it said something about the emission control. When is it located and the possible cost of repairs

If it wont run, have it towed to a repair shop for diagnosis! Way too many possibilities!
There is no single part of emission control. It's the system that the engine runs by.
