If your 2008 Ford Focus's check engine light comes on, the first step is to safely pull over to the side of the road. After stopping safely, use an OBD II scan tool to retrieve the code from the engine. These codes can range from minor issues like a loose gas cap to more critical engine problems such as cam malfunctions. It is advised to check the code before resetting it, as a serious issue will likely trigger the light to come back on. It is important to address the underlying problems causing the check engine light to illuminate rather than simply turning it off.
