The o2 sensor sends data to the vehicle’s onboard computer to indicate the right mixture of air and fuel that enters the cylinders in your engine. Web the check engine light on your 2012 ford fusion will consistently shut itself off if the issue or code that caused it to turn on is serviced. The best way to clear the check engine light is to pull the trouble code, identify and fix the issue and then drive your fusion around until the module that threw the code recognizes that the problem is fixed.
