Thats is a great question. It may, and it may not. I am leaning towards not. There is one way to know for sure.
If it did generate a code, it would not be a "A" priority code, most likely would be a "C" or "D" priority, which would not illuminate the Engine light.
Great question. It would be handy to know the answer for sure.
