A lot of people want the check engine light to go off.
I am doing some research for school and I want it to come on. Does anyone know some simple problems or faults I can create with a vehicle in order to make the check engine light come on?
These would be faults that the car can run with (not necessarily drive with) without causing permanent damage, hopefully.
I am trying to develop software for a school project that can track Error codes going on and off over time.
I understand that any advice you give is for educational purposes and don't hold anyone here accountable if something goes catastrophically wrong.
