Answers :

The check engine light will come on for more than just a engine problem but usually something else on the car isn't functioning properly. I had a car with a low fluid level in the transmission that would not read but the check engine light came on.
\015\012It is a warning and if it doesn't scan check the rest of the car for what isn't functioning since for sure it is connected.
\015\01250% of the time a check engine light comes on it is a loose or bad gas cap. Check that first. The oxygen sensor is next but it will read on your reader.
I dont know why but try a different part store or dealership
